Uninterruptible Power Supply Unit ABP-230-50 for Critical Load Applications

The single-feeder UPS is designed to create an uninterrupted three-phase network with voltage 230/380 V, frequency 50 Hz to supply especially critical consumers. Power supply is carried out from three-phase AC network with voltage 380 V, frequency 50 Hz, with the possibility of organising bypass. Voltage formation is provided by means of static converter I-TTPT-150-220-50-B.

Uninterrupted operation is provided by means of the AB cabinet. The device ABP-230-50 provides: -galvanic isolation of the output power supply circuits from the input power supply circuit by means of transformer TC3M-63-OM5 380/400 D-Un1, as well as signalling circuits from the power supply circuits; -accumulator support by means of lead-acid batteries; -protection of the output feeder, in case of: presence in the output power supply circuits of overload currents from 1.1 Inom to 1.2 Inom with duration not less than (12 ± 2) s; short-circuit currents in the output circuits of the power supply exceeding 1.2 INom with duration of at least (12 ± 2 s)...
