Insulation monitoring device for unearthed DC systems (IT systems) DC 50 V up to 400 V Suitable for the charging of electric vehicles acc. to Japanese charging standard CHAdeMO Product description 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...

The ISOMETER® uses the serial hardware interface RS-485 with the following protocols: • BMS The BMS protocol is an essential component of the Bender measuring device interface (BMS bus protocol). Data transmission takes place with ASCII characters. • Modbus RTU Modbus RTU is an application layer messaging protocol and it provides Master/Slave communication between devices that are connected altogether via bus systems and networks. Modbus RTU messages have a 16-bit CRC (Cyclic Redundant Checksum), which guarantees reliability. • IsoData The ISOMETER® continuously sends an ASCII data string...
