The 11RT G2 1-3 kVA relay card is a relay card specially developed for the PowerValue 11RT G2 1-3 kVA UPS system. This card enables smooth integration of the UPS systems into existing systems and allows remote monitoring of the UPS system. Messages from the UPS system can be transmitted via potential-free contacts, for example to a control system, which allows the operator to react quickly to faults or critical states of the UPS system.
