ISOMETER® isoCHA425

• 根据 CCS 或 CHAdeMO 监控直流充电站的绝缘电阻
• 在直流系统中，可以在1秒内检测到电压范围介于50V和500V之间的不对称绝缘故障
• 可以在10s内检测对称绝缘故障
• 在欠电压和过电压检测的情况下，测量系统电压(真实有效值)
• 直流系统对地的电压测量(L+/PE和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 C_e 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.
