DWA01 and PWA01 are precise over or under cos ϕ monitoring relays.

The relays monitor their own power supply voltage and the current of a balanced 3- phase system.

For current measure direct connection, 5A standard current transformers and MI CT can be used.

The LED’s indicate the state of the alarm and the output relay.
