直流绝缘控制器 ISOMETER® isoCHA425

RS485ModBUS RTU

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 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. 特点 符合日本充电标准CHAdeMO的绝缘监视仪，监视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400V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) 自适应系统泄露电容，可高达2 μF 可选启用延迟、响应延迟和延迟释放 2组独立可调响应值，其范围为5…250 kΩ（报警1和报警2） 通过LED灯(AL1、AL2)，显示屏和报警继电器(K1、K2)发送报警信号
