The HE-V relay is a miniature power relay that can conduct and cut off high DC voltage or high currents which is ideal for the rapid shutdown system. Using a 2FormA contact arrangement, this relay is capable of both positive and negative line cut-off on the DC side of the inverter. Using a blow-out magnet mechanism and serial contact connection, the electrical arc is dissipated upwards along the insulated walls of the relay. This relay helps system efficiency by achieving a low coil holding voltage to minimize the power consumption. The design is also intended to maintain a 3.8 mm contact gap and the necessary creepage and clearance distances to meet the required IEC regulations for the rapid shutdown application.
