Switched-mode power supplies

БЖ03

General-purpose AC/DC converter.

Uin: AC – 85...265 V; DC – 120...370 V;

Uout regulated 3...24 V; 3 W,

for PCB mounting (44×33×22) mm.

БЖ100

General-purpose AC(DC)/DC converter.

Uin: AC – 176...265 V; DC – 250...370 V;

Uout regulated (5, 12, 15, 24, 27, 36, 48, 60) V; 100 W,

DIN-rail, 70 mm wide.

БЖ400м

DC/DC converter.

Designed to supply static and dynamic loads with a regulated 220 V DC output at a continuous 400 W, from a 110 V DC source.

Can be used to supply vacuum circuit breakers and other loads of a capacitive nature.

БЖ600м AC(DC)/DC converter. Designed to supply automatic vacuum circuit breakers and other loads with a capacitance of no more than 4700 µF.
If a capacitor bank larger than 4700 µF is used, a 25 W, 47 Ω wirewound resistor must be connected in series with the bank to limit the charging current.

БЖ1000 AC(DC)/DC converter.
Designed to supply static and dynamic loads with a regulated 110 V or 220 V DC output at a continuous 1000 W, from a DC, rectified or AC source. It limits the maximum current drawn from the source to 5 A.
Uin: AC – 176...265 V; DC – 250...370 V.
Can be used to supply vacuum circuit breakers and other loads of a capacitive nature.

ЭПРА SOX 18-12

Electronic ballast.

Designed to drive SOX-E 18 W low-pressure sodium lamps in street lighting luminaires equipped with a solar panel and a battery.

Supply voltage (10...15) V

ИПС1

Power supply for high-brightness LEDs

Supplies luminaires using Luxeon LXHL-type or equivalent high-brightness LEDs from a ~220 V mains supply.

Designed to supply backlight modules, traffic lights, interior lighting units, exterior lighting modules, signal and decorative lighting, RGB LED drivers and flat display panels; it can also be used as a general-purpose DC source or a battery charger.

Emergency trip unit designed to trip (6-10) kV vacuum circuit breakers using a de-shunting scheme on an AC control supply.
The energy for charging the capacitor bank and issuing the trip command comes from the secondary winding of the current transformer during a short circuit in the main circuit.
The emergency trip unit charges the capacitor bank of the vacuum circuit breakers and issues a trip command once enough energy has been accumulated to open them.
Can be used in vacuum circuit breakers, protection and automation schemes, and other equipment.

Emergency supply unit
The БАП is built as an electronic module housed in a plastic enclosure.
Nominal input voltage when supplied from the mains (from the transformer
auxiliary services), V — 220
Permissible deviation from nominal supply voltage for the БАП
from the mains, % 65-120
DC output voltage at nominal mains voltage
and with a vacuum circuit breaker connected, V — 290
Pickup voltage of the trip-enable relay, at a voltage on
capacitor bank, V — 187 +2%.
БАП load capacitance, max, µF — 2000
Nominal capacitance of the built-in capacitor that closes
of the breaker when supplied from the mains, µF — 4700 µF
The time needed to prepare for tripping, while charging the capacitor bank built into a ВР1 vacuum circuit breaker, as a function of the current in the relay winding of the current transformer, is given in Table 1 (typical values).

ПП110М
The converter is designed to supply ВР series automatic vacuum circuit breakers and other loads with a capacitance of no more than 6800 µF.
If a capacitor bank larger than 6800 µF is used, a 25 W, 47 Ω wirewound resistor must be connected in series with the bank to limit the charging current. The converter can be used stand-alone or as part of a vacuum circuit breaker.
The converter is built to climatic category У, placement category 2 per ДСТУ ГОСТ 15150-69, and is designed to operate at temperatures from -25°C to +55°C, relative humidity up to 80% and atmospheric pressure from 650 to 800 mm Hg.
The converter is intended for operation in a non-explosive atmosphere, free of gases and vapours in concentrations that attack metal and insulation, and free of saturated water vapour and conductive dust.
Permissible vibration: 1 to 35 Hz at an acceleration of 4 m/s².
