Product Details

As an important part of the solar power generation system, the photovoltaic inverter can convert the DC current output generated from the photovoltaic panel into AC current, which can then be incorporated into the commercial grid or other off-grid power systems. In the grid connection interface, the electromagnetic relay on the AC side of the inverter plays a key role as a switching device to provide the necessary safe "open circuit" function.

IM-NE801A is a two-pole PCB power relay for new energy power generation(EV Charger, Solar Inverter, Energy Storage System). It features a high-capacity resistive switching load rating of 40A@277VAC for 50K cycles (@32A 230VAC) or 20K cycles (@40A 230VAC). The relay also features a mirror contact structure (compliant with EN60947-4-1) which uses a 2 Form A contact arrangement. IM-NE801A has a normally open contact gap of 3mm, which makes this relay VDE0126 compliant with European photovoltaic standards and meets the 4kV surge breakdown voltage between contacts required to be compliant with the EN61810-1 Industry standard.

Compared with other power relays on the market, the main advantages of lie in 3mm conntact gap:

Its contact distance can be up to 3mm, and the contact spacing of the general relay is about 0.8mm or 1.5mm.In some ways this feature made contact between medium pressure can improve a lot, the higher the withstand voltage value, and also solve the problem of contact resistance increase rapidly, etc, under non-operation status it can avoid wrong operation or damage caused by external factors. which improves the tensile arc resistance of the contact and prolongs the service life of the relay.

Relays Used in Solar

In solar application, for safety cut off the AC side, Relays are used for safety cut off on the grid(power network). The relay must cut off the circuit to prevent abnormal currents that occur from affecting the commercial poer supply. Power relays are required as safety measures to protect the power supply system.
