To satisfy new standards including IEC 62752 and IEC 60364-7-722, the charging of electrical
vehicles requires residual current sensors to avoid hazardous situations in cases
where the vehicle battery (DC) is connected to the home power supply (AC). Generally,
AC/DC-sensitive residual current sensors can be used where direct current and alternating
current circuits are directly connected and therefore AC/DC leakage currents can occur.

• IEC 627582 and UL 2231 version available
• Frequency range DC to 2 kHz
• Full load current up to 80 A rms (1-phase) or 3 x 32 A rms (3-phase)
• Switching output for 6 mA DC/30 mA rms (IEC) or 5 mA rms/20 mA rms (UL2231)
• Error output (Integrated self-monitoring and test functions)
• Measurement resolution 0.2 mA

• Using a VAC/Bender DI sensor integrated into an IC-CPD or wall box
