Electrical safety monitoring device ISOMETER® isoCHA425

for medical IT systemsmanual

Monitoring the insulation resistance for DC charging stations according to Japanese charging standard 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 of DC charging stations according to the Japanese charging standard CHAdeMO for voltages between DC 50 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 2 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.
