RCMS150CH Differenzstrom Auswertegerät

The six-channel RCMS150 residual current monitoring device is intended for measuring DC and AC residual currents in earthed power supplies that can arise due to insulation faults on loads with six-pulse bridge rectifiers or half-wave rectifiers with smoothing. The device is able to measure residual currents up to a level of IΔ = 500 mA in a frequency range of DC 0...2 kHz. Two separately adjustable response values can be used to differentiate between pre-warning and alarm.

The device has an RS-485 interface via which the measured and alarm values are transmitted. Parameterization is also possible via this interface.

Main features:

- Alternative to iso-testing in accordance with DGUV V3

- All-current sensitive measured value acquisition type B

- Pure DC fault evaluation

- Can be used in the smallest of spaces

- RS-485 with BMS Data can be visualized

Functions and features:

- Permanent residual current monitoring in accordance with DGUV regulation 3
