Power Supply with UPS Electronics
ZD12UPS / ZD24UPS 60VA
The device is used for continuous power supply of process stations, telemetry, and GPRS systems.
It operates using 15V (24V) / 50Hz power from a standard 230V mains transformer.
The output is stabilized DC voltage 12V (24V) and auxiliary, unstabilized voltage 20V (32V).
In case of mains power failure, the output is electronically switched to a backup maintenance-free battery 12V (24V).
The system operates in emergency mode and the device informs with a logic level about the loss of mains voltage. The power supply electronics ensure control of the output voltage and automatically disconnect the battery when the voltage drops below the limit value (battery undervoltage protection). When the mains voltage is restored, it correctly recharges the battery and keeps it in a charged state.
