Monitor DC, AC and 3-phase AC networks up to 690V for undervoltage and overvoltage and thus protect consumers from damaged caused by deviations in the supply voltage.

Devices is an OR circuit detect when a current flows in one of up to 12 monitored lines.

Current relays is an AND circuit monitor whether current is flowing in all 3 monitored lines and signal e.g. failure of a phase or a customer.

With integrated evaluation electronics for current detection yes/no, without auxiliary voltage.

Simple detection of the operating status of an AC or DC consumer. Evaluation directly with the digital input of a PLC or a current relay for flow detection.

As measuring relays for monitoring DC and AC flows.
Currents of practically any magnitude can be monitored with external shunts or transformers.

In conjunction with the appropriate transformers monitor fault currents in earthed networks.

They signal insulation faults before major damage occurs and help to avoid shutdowns.

Optimize self-consumption of self-generated energy.

Monitor the frequency in the range of 10-500Hz in 20-830V AC networks.

The version with transducer provides an isolated 0/4-20mA or 0-10V output signal corresponding to a freely selectable frequency range.

Install 2/3 more generation capacity than the grid connection allows.

Certified monitoring of the contractually agreed effective connected power Pav,e.

Monitor voltage, frequency and vector shifts on generation plants.

Grid and system protection in accordance with VDE-AR-N 4105 and others.
