The ISOMETER® isoCHA425HV in combination with the AGH420-1/AGH421-1 coupling device monitors the insulation resistance for DC fast charging stations according to the CHAdeMO standard or according to the Combined Charging System (CCS) for nominal system voltage ranges between DC 0 V and 1000 V. ■ Switchable between CCS (Combined Charging System) and CHAdeMO ■ Detection of symmetrical and asymmetrical insulation faults ■ Electrically isolated Modbus RTU interface ■ Display of the fault location (DC-balanced) ■ Only one device for use in all regions and applications ■ Compact design for optimum...

Can be used worldwide thanks to international approvals Optimised and accelerated testing and approval processes for UL-certified charging stations High flexibility and low variant diversity thanks to switching between CHAdeMO and CCS mode ococ OOQO A high level of electrical safety is a priority for DC charging stations. In order to minimise the risk to the user, the ISOMETER® isoCHA425HV fulfils all the important requirements placed on the insulation monitoring device by the standards and regulations.

■ Detection of insulation faults up to 2 MQ ■ Maximum allowed system leakage capacitance ■ Active measuring method can detect symmetrical and asymmetrical insulation faults ■ Voltage measurement with overvoltage and undervoltage detection ■ Automatic device self-test with connection monitoring ■ High system reliability ■ High availability of the charging station ■ Ideal for e-bus charging applications etc. thanks to high permissible leakage capacitance

Most compact design in the market: Flexible arrangement of insulation monitoring and coupling device Push-In wire connectors ■ Optimum utilisation of the available installation space within the charging station ■ Time savings during production thanks to fast wiring The demand for elegant and compact fast charging stations is on the rise. The ISOMETER8 isoCHA425HV supports this trend with its compact design.

“With the isoCHA insulation monitor from Bender, our charging systems are safe and fulfil the current charging standards. With its high, permissible system leakage capacitances, it makes it possible to charge large electric vehicles. ” Dr. Raoul Heyne, ADS-TEC Energy, Senior Expert Chargin

▪ RS-485 ▪ Modbus RTU ▪ IsoData ▪ LC display ▪ Password protection against unauthorised parameter changes Benefits: ▪ Q uick and easy integration of the IMD in the charge controller using standard protocols ▪ S imple troubleshooting on site by me

In fast charging stations with dynamic load distribution to two charging points, one IMD often has to be disconnected from the grid to avoid interference as long as the maximum power of a charging station is only made available to one vehicle. The new AGH421-1 coupling device in combination with the ISOMETER® isoCHA425HV enables disconnection from the grid without the installation of additional switching units. Benefits: ▪ C ost and space savings within the charging station by eliminating additional switching units ▪ R educed wiring effort during the production

Both IMDs are active Link voltage Charging voltage Vehicle battery voltage Variable DC/DC converter Galvanically Isolated Variable DC/DC converter IMD 2 disconnected from the system to be monitored Link voltage Charging voltage Vehicle battery voltage Variable DC/DC converter Galvanically Isolated Variable DC/DC converter The entire available power is used for charging one vehicle. IMD2 must be disconnected to avoid interference
