ISOMETER® isoCHA425
- Monitoring the insulation resistance for DC charging stations according to CCS or CHAdeMO
- Detection of asymmetrical insulation faults in the DC system voltage range between 50 V und 400 V within 1 s
- Detection of symmetrical insulation faults within 10 s
- Measurement of the system voltage (true RMS) with undervoltage and overvoltage detection
- Measurement of DC system voltages to earth (L+/PE and L-/PE)
The ISOMETER® monitors the insulation resistance RF for DC fast charging stations according to CHAdeMO standard or according to Combined Charging System (CCS) for nominal system voltage ranges between DC 0 V and 400 V.
Asymmetric insulation faults are reported with a response time ≤ 1 second. Symmetrical insulation faults within 10 seconds. The maximum permissible system leakage capacitance Ce is 5 μF.
In order to meet the requirements of applicable standards, customised parameter settings must be made on the equipment in order to adapt it to local equipment and operating conditions.
Please heed the limits of the range of application indicated in the technical data. Any use other than that described in this manual is regarded as improper.
