Guards of automatic switching on a reserve of AVR (ShchAP)

Guards of the AVR (ShchAP) series are intended for automatic switching on back supply of electroreceivers in case of disappearance of the main power supply with the subsequent return to an initial state at recovery of the main power supply of electroreceivers.

Schemes of guards have two options of execution:

• with the time cut-out on each input (are established on the panel with the equipment)
• with the rotary switch on each input (is established on the guard panel).
