Pro­jec­tors in home the­ater sys­tems are rec­om­mend­ed to be equipped with a UPS, as their micro­proces­sors are designed to smooth­ly turn off the cur­rent.

It is impos­si­ble to imag­ine the life of a mod­ern per­son with­out a vari­ety of elec­tri­cal appli­ances that sur­round him lit­er­al­ly at every step. How­ev­er, the obvi­ous ben­e­fits of progress come at the price of increas­ing reliance on cen­tral­ized pow­er dis­tri­b­u­tion sys­tems.

The own­ers of many coun­try man­sions are forced to solve the prob­lem of an unsta­ble sup­ply of elec­tric­i­ty to their homes. It affects every­one, includ­ing own­ers of cot­tages locat­ed in the most pres­ti­gious vil­lages. Any inter­rup­tions in pow­er sup­ply dis­rupt the usu­al course of life of the pop­u­la­tion and are per­ceived as an emer­gency. Cit­i­zens are lit­er­al­ly cut off from all the ben­e­fits of civ­i­liza­tion: the TV, tele­phone do not work, “glob­al warm­ing” in the refrig­er­a­tor has a detri­men­tal effect on the prod­ucts stored there … Even short-term pow­er fail­ures can lead to unpleas­ant con­se­quences. This is espe­cial­ly true for com­put­ers and oth­er devices that may suf­fer from a sud­den “dooms­day”. There are cas­es when, due to pow­er out­ages, the proces­sors of wash­ing machines and dish­wash­ers failed. In gen­er­al, the more com­plex and expen­sive the equip­ment, the more like­ly it is that due to the whims of the ener­gy sup­ply, it will be hope­less­ly dam­aged.

Anoth­er prob­lem that own­ers of cars, garages and sub­ur­ban areas espe­cial­ly often face is that the pos­si­bil­i­ty of con­nect­ing to the main pow­er sup­ply net­works does not exist every­where. Mean­while, some­times there is a need to con­nect elec­tri­cal appli­ances in the “field” con­di­tions. How to be in a sim­i­lar sit­u­a­tion?

The sim­plest option that will help once and for all solve the prob­lem of ener­gy sup­ply,- dupli­cate the oper­a­tion of the pow­er sys­tem with per­son­al pow­er sup­plies. These devices will help out the own­ers when it is nec­es­sary to orga­nize the work of elec­tri­cal appli­ances in places where there are no pow­er grids. BUTThe most advanced unin­ter­rupt­ible pow­er sup­plies (UPS) will pro­tect com­put­ers and house­hold appli­ances dur­ing an emer­gency pow­er out­age. Oth­er advan­tages of such devices (com­pared, for exam­ple, with gaso­line and diesel gen­er­a­tors) are small size, envi­ron­men­tal safe­ty and ease of use. So, UPS do not pol­lute the air with exhaust and oper­ate silent­ly. The cost of portable mod­els with small capac­i­ty bat­ter­ies- 1–1.50 $, and the prices for pow­er­ful and sta­tion­ary UPSs can reach sev­er­al tens and even sev­er­al thou­sand dol­lars.

Here is what the block dia­gram of an unin­ter­rupt­ible pow­er sup­ply looks like. Tomains, an invert­er (1) is con­nect­ed, which pro­vides a sta­ble out­put volt­age of 220B. It feeds the house net­work (2). Toa bat­tery pack (3) is also con­nect­ed to it. For all pow­er sources, bat­ter­ies are used, which are char­ac­ter­ized by the out­put volt­age, capac­i­ty and oth­er para­me­ters (they will be dis­cussed lat­er). In addi­tion to bat­ter­ies, devices may include an elec­tron­ic con­trol unit that allows the device to oper­ate as a UPS in auto­mat­ic mode, an out­put volt­age sta­bi­liz­er, and an auto­mat­ic charg­er.

When choos­ing a source of ener­gy sup­ply, clear­ly define the range of tasks that you are going to solve with its help. If you need it to con­nect pow­er tools in the gar­den, as well as a pow­er source for emer­gency light­ing and start­ing cars or snow­blow­ers, then a portable UPS, such as the MP series, is suit­able. P4 PRO (MOBILEN, Europe), EFOY (SFC, Ger­many). These mod­els dif­fer from each oth­er in bat­tery capac­i­ty, max­i­mum start­ing cur­rent, gen­er­at­ed cur­rent volt­age, weight and full charge time.

Bat­tery capac­i­ty. The amount of charge that the bat­tery can give dur­ing oper­a­tion. Mea­sured in ampere-hours (Ah). The larg­er the capac­i­ty, the longer the devices con­nect­ed to the bat­tery will be able to work. Large capac­i­tance is espe­cial­ly impor­tant when con­nect­ing pow­er­ful devices that require a lot of ener­gy for a long time. This applies, for exam­ple, to cir­cu­lar saws, elec­tric weld­ing andt.n. If the device is used to pro­tect com­put­ers and sim­i­lar equip­ment from pow­er fail­ures, the capac­i­ty of the bat­ter­ies is usu­al­ly not too impor­tant.

The max­i­mum val­ue of the start­ing cur­rent. It is mea­sured in amperes (A). It is tak­en into account if you are going to use the device to start car engines. Portable pow­er sup­plies are capa­ble of gen­er­at­ing an inrush cur­rent of 200‑1400A. Iif the cur­rent is 200And it is suit­able for start­ing engines of gar­den equip­ment, motor­cy­cles and small cars, then a cur­rent of 1400And it is suit­able for engines of trucks, includ­ing diesel ones.

Mod­el MP 747 (MOBILEN) has a mass of only 7.1kg
Weight. An impor­tant indi­ca­tor for portable devices, espe­cial­ly con­sid­er­ing that some of them weigh 15–20kg.This heav­i­ness is due to the design of bat­ter­ies intend­ed for indoor use. ATIn such cas­es, lead-acid bat­ter­ies with a sealed case and a gel elec­trolyte are used. They cost more than acid-based alka­line bat­ter­ies, but they have many advan­tages. First­ly (and most impor­tant­ly), such bat­ter­ies do not emit harm­ful gas dur­ing oper­a­tion. There­fore, they can be placed indoors with­out risk to health. These bat­ter­ies are con­ve­nient in that they can work in any posi­tion (not only when installed ver­ti­cal­ly), are resis­tant to low tem­per­a­tures, do not require elec­trolyte top­ping up and are easy to main­tain. But safe­ty comes at the price of increas­ing the mass of the device. There­fore, if the device is sup­posed to be used “a lit­tle, but often” and in dif­fer­ent places in the gar­den, it may make sense to choose a mod­el with a small mass (4–5kg).

Out­put volt­age. Most mod­els give a direct cur­rent volt­age of 12C. Elec­tron­ics and appli­ances require AC 220 to pow­erB. To be able to con­nect them, you need addi­tion­al devices- invert­ers, or cur­rent con­vert­ers. Their main char­ac­ter­is­tic- rat­ed out­put pow­er (from tens of watts to sev­er­al kilo­watts).

For online security

Unin­ter­rupt­ible pow­er sup­plies are used when the pow­er sup­ply is unsta­ble. Such a device remains con­stant­ly con­nect­ed to the net­work, and devices sen­si­tive to pow­er fail­ures are con­nect­ed to it, in turn. With nor­mal mains volt­age, the invert­er works to recharge the bat­tery or “in the back­ground” (in this case, the ener­gy con­sumed by it is min­i­mal and amounts to 20–50Tue). But as soon as the sup­plied volt­age drops below a crit­i­cal lev­el, the invert­er auto­mat­i­cal­ly starts to com­pen­sate for the lack of pow­er at the expense of the bat­tery resources.

Desk­top Back­up Sys­tem BK325-RS (APC) Unin­ter­rupt­ible pow­er sup­plies are also used to com­pen­sate for peak loads dur­ing pow­er con­sump­tion. If, for exam­ple, the in-house sys­tem is designed for a con­sump­tion of 2.5 kW, the simul­ta­ne­ous con­nec­tion of sev­er­al pow­er­ful devices can lead to the fus­es (plugs) being turned off. The UPS mon­i­tors these fluc­tu­a­tions in con­sump­tion and, if nec­es­sary, com­pen­sates for the lack of elec­tric­i­ty with the reserve accu­mu­lat­ed in the bat­ter­ies. Among the man­u­fac­tur­ers of house­hold UPSs on the mar­ket, the most notable are APC, XANTREX, STATPOWER, HEART, EATON (all- USA) and “IRBIS‑T” (Europe).

ATDepend­ing on the design of the elec­tron­ic con­trol cir­cuit, two types of UPS can be dis­tin­guished: Offline and Online. Devices of the Offline type, which are sim­ple in design, switch to pow­er sup­ply from bat­ter­ies only when there is a pow­er out­age or a sharp drop in mains volt­age. Online type devices pro­vide an AC out­put with opti­mum fre­quen­cy and sine wave­form char­ac­ter­is­tics. This tech­nique pro­vides the best pro­tec­tion for the devices con­nect­ed to it, but it is also not cheap. The aver­age cost of a sys­tem with a capac­i­ty of about 1.5 kW, designed for a day of autonomous oper­a­tion, is 700 $ FROMAs pow­er increas­es, so does the price. For exam­ple, the SW 4548E (XANTREX) (4.5 kW) pro­vides pow­er for 16h and costs about 200 thou­sand rubles.

Unin­ter­rupt­ible pow­er sup­plies for coun­try hous­es are often made in a sta­tion­ary ver­sion, and there­fore take up a lot of space. The bat­ter­ies in them have a large capac­i­ty, which allows you to main­tain the sup­ply of elec­tric­i­ty for many hours.

An impor­tant para­me­ter for a UPS is the time it takes to auto­mat­i­cal­ly switch pow­er from mains to bat­ter­ies. Offline-type house­hold devices pro­vide switch­ing in an aver­age of 30–40ms (mil­lisec­onds) and the Online UPS reduces this time to 2ms. A per­son­al com­put­er is usu­al­ly able to with­stand a “pause” of up to 50–100ms, so that most UPSs can ensure its per­for­mance.

For autonomous pow­er sup­ply for a long time, a com­bined sys­tem con­sist­ing of a UPS and a gas gen­er­a­tor is often used. In the event of a pow­er out­age, the UPS begins to con­sume bat­tery life. If the pow­er sup­ply is not restored with­in the set time, the UPS will auto­mat­i­cal­ly start the gen­er­a­tor. Such autonomous sys­tems are able to work until the fuel in the tank runs out. The cost of the com­plex- from 1200$. (half of the amount will be the cost of the gen­er­a­tor). If nec­es­sary, you can increase the capac­i­ty of the com­plex by adding addi­tion­al bat­ter­ies.

There are oth­er, more promis­ing options for autonomous pow­er sources. For exam­ple, a set of a sta­tion­ary UPS and an autonomous source of elec­tric­i­ty (solar bat­tery, wind gen­er­a­tor andt.P.). Hav­ing once paid for a set of autonomous equip­ment, the own­er of the house saves him­self from reg­u­lar com­mu­ni­ca­tion with the sup­pli­er of main elec­tric­i­ty, the steady increase in its cost, inter­rup­tions and pow­er surges. Sim­i­lar projects have already been imple­ment­ed and are work­ing quite suc­cess­ful­ly not only abroad, but also in EU. We plan to talk about them in one of the next issues of the mag­a­zine.

bat­tery of bat­ter­ies

Electric bins “SOLAR TECHNOLOGY” A seri­ous prob­lem for many own­ers of sta­tion­ary UPS is the weight and dimen­sions of these devices. Suf­fice it to say that in some cas­es the total mass of such UPSs reach­es sev­er­al tons! Per­haps, for their place­ment, it will be nec­es­sary to make a sep­a­rate foun­da­tion, such as, for exam­ple, for a stone oven. To store bat­ter­ies, it is best to use a room with a con­stant pos­i­tive tem­per­a­ture and low humid­i­ty (for exam­ple, a warm and well-ven­ti­lat­ed base­ment). Some­times they are placed in a sep­a­rate util­i­ty build­ing. Most mod­ern bat­tery mod­els tol­er­ate cool­ing down to ‑20 quite well.C, worse- Damp­ness, espe­cial­ly mois­ture con­den­sate that forms, which leads to cur­rent leak­age and rapid bat­tery dis­charge. For their stor­age, spe­cial­ly made met­al racks are most often used that can with­stand the nec­es­sary load.
