The PS-203-40А and PS-203-60А power supply units with a rated power of 1000 and 1512 W are designed to operate with 110/220VAC and convert the input voltage into a regulated 24VDC. Both power supply units have an input for a standby storage battery (24 VDC), which switches over automatically in the event of a power supply failure.

A power failure actuates the closing of the built-in dry relay contacts. The units are suitable to supply shipboard equipment, which is sensitive to input voltage surges and peaks. The PS-203-40А (60А) can be used in a dry environment (IP22). The units have galvanic isolation of input/output feed circuit, overvoltage and current overload protection.
