Features
- Monitoring of asymmetrical insulation resistances for unearthed DC systems
- Measurement of the system voltage (r.m.s. and DC) with undervoltage and overvoltage detection
- Measurement of the system DC voltages to earth (L+/PE and L-/PE)
- Configurable adaptation to the system leakage capacitance up to 5 μF
- Selectable start-up delay, response delay and delay on release
- Two separately adjustable response value ranges of 1…100 kΩ (Alarm 1, Alarm 2)
- Alarm signalling via LEDs (AL1, AL2), a display and alarm relays (K1, K2)
- N/C operation or N/O operation of the relays selectable
- Measured value indication via multifunctional LCD
- Fault memory can be activated
- RS-485 (galvanically isolated) including the following protocols:
– BMS interface (Bender measuring device interface) for data exchange with other Bender components
– Modbus RTU
– IsoData (for continuous data output) - Password protection to prevent unauthorised parameter changes
Applications
- Simple battery systems
- Conveniently sized DC control voltage systems
- DC lamp circuits
