DC power supply backup relay type PZ-1
Application
The PZ-1 relay is used for the automatic supply voltage switching. In case of the basic voltage Up loss the relay switches the system to reserve voltage Urez. supply. When the basic supply voltage is back, the relay re-switches the system. The relay is used for switching the DC supply voltage.
