Backup power supplies in the cover

Backup power supplies in the cover


Backup power supplies 75PS13V8 K40/5A and 1PS13V8 K40/10A are designed to power device that require a continuous supply of direst current voltage 13,8 Vdc, respectively 12 Vdc.

They are designed for connection of backup accumulator with a capacity from 17 Ah to 40 Ah. The acumulator is connected permanently to the power supplies. Is maintained fully charged circuit and there is no danger of accumulator overcharging.

Also the circuit ZOM.01 ensures compliance with the set charging current.

The power supply is placed in a metal cover with ventilation holes, it is equipped with a mechanical lock and two tamper contacts. One indicates a opening of the cover and second a removing of the power supply (machanical cover) from assembly place.


> Cover with space for accumulator up to 40 Ah

> Accumulator protection against deep discharge

> Optional accumulator charging rate, depending on the set charging current

> Check accumulator voltage every 1 second

> Visual indication of the state - 4 LED diodes

> Signaling unconnected accumulator when connected network 230V/50Hz

> Lockable cover with protection contact of opening the cover

> Protection contact with indication of removing from assembly place

> Electronic overload protection

> Adjustable charging current value

> High efficiency according to applied switched supplies

> Compact design for wall assembly
