PS-3x-1
Product model withdrawn from sale

Switch-mode power supplies are designed to supply elements of gas detection systems (control modules, detectors, warning boards and signalling devices) with a nominal supply voltage of 12 V DC or 24 V DC.

They have a possibility of automatic power backup from an internal gel battery (or a pair of batteries) type AKU.

Features

• output voltage separated by galvanic separation;
• possibility to back up the power supply from the internal maintenance-free battery (ordered separately) in case of mains voltage loss;
• output protection against overload and short circuit;
• limit of the battery charging current;
• optical indication of the presence of input and output voltage;
• optional: module with relay outputs to indicate mains failure and presence of output voltage PS-MR.
