UPS 400-24

About

The equipment is designed to ensure uninterruptible power supply for the equipment with operating voltage 24 V.

The equipment may be applied as emergency/standby DC power sources 24 V for various equipment (including shipborne).

Description

The equipment is designed for operation with three-phase four-wire AC network, frequency 50 Hz and voltage 380/400 V (if N is absent, the scope of delivery includes a transformer 400/400 Δ-Y).

To ensure power redundancy, the equipment may be powered by two lines (main/standby). A built-in automatic transfer equipment provides automatic transfer to standby power and vice versa when power mains fails.

The equipment automatically switches over to built-in lead-acid batteries in the event of input power failure.

Features

• Main and standby power indication
• Signal output to alarm warning system (AWS) in the event of faults (dry contact)
•  AB protection against deep discharge, overload and short circuit
•  Automatic power transfer to AB in the event of power mains failure and vice versa
