FAQ of Leakage Sensor:
Q1:what is this?
A:It's an EV type residual current monitor, providing leakage protection for Mode2/Mode 3 charging
and complying with the requirements of the relevant standards for leakage protection in the European
market for charging posts
Q2:How does this work?
A:Smoothed DC residual currents can occur in certain power electronics applications. Smoothed DC
residual currents can prevent conventional AC-type and type A residual current protection devices (RCDs)
from functioning properly, with RCD inactivity or normal operation malfunction in the event of an electric
shock. EV charging is a typical load that can generate a smooth DC residual current component and for
effective personal safety protection, the IEC 62955 standard provides for the protection of possible smooth
DC residual currents from EV charging. It effectively eliminates the loophole of AC 30mA residual current
protection caused by smooth DC residual components and effectively disconnects the conductive part, making
it far safer and more reliable than the combination of residual current monitoring module and relay on the charging
post board.
Q3:Why do AC charging posts generate smooth residual currents?
A:The main reason is that the insulation of that part of the DC/DC inside the OBC is broken, which can be caused
by driving the car for a long time, bumps and bumps, careless maintenance, etc., and then smooth DC residual
current will be generated.
Q4:Why choose it?
A:This product combines 6mA DC monitoring, detection and 30mA Type A residual current protection in one device.
It offers the following advantages: Safe and reliable Integrates multiple protection against short circuit, overload,
residual current (sinusoidal AC, pulsating DC and smooth DC faults) in one device; the neutral pole can be opened
and closed to cut off both the fire and zero wires in the event of a fault, making the charging process safer.
