Model: Customized

In order to meet some special requirements, we can integrate frequency monitoring functions into voltage monitoring relays or current monitoring relays.

Mainly inclusive of the following:

1. Three-phase monitoring relays + frequency monitoring function (40 ~ 70Hz)

2. Single-phase monitoring relays + frequency monitoring function (40 ~ 70Hz)

3. Current-monitoring relays + frequency monitoring function (40 ~ 70Hz)
