ISOMETER® isoEV425 with AGH420
- Insulation monitoring device for AC 690 V and DC 1000 V IT systems
- Monitoring of DC charging stations for electric and hybrid vehicles
- Settings in accordance with IEC 61851-23
- Parameter settings by the customer not required
Currently there are no microcontrollers available for the isoEV425-D4-D+AGH420. Please use the isoCHA425HV-D4-4+AGH420-1.
The ISOMETER® of the isoEV425 series monitor the insulation resistance of unearthed DC-charging stations for electric vehicles (IT systems) DC 0…1100 V DC from the charging station to the motor (AC 0…793 V).
Due to a separate supply voltage de-energised systems can also be monitored.

Features
- Monitoring for DC charging stations (mode 4 acc. to IEC 61851-23) for charging of electric vehicles
- Measurement of the mains voltage (r.m.s.) with undervoltage and overvoltage detection
- Measurement of DC voltages system to earth (L+/PE and L-/PE)
- Automatic adaptation to the system leakage capacitance up to 5 μF or 20 μF
- Automatic device self test with connection monitoring
- Selectable start-up delay, response delay and delay on release
- Two separately adjustable response value ranges of 1kΩ …500 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
- DC charging stations for electric vehicles according to IEC 61851-23
