High capacity PCB relay from Finder

10 November 2013

For applications where high current loads need to be switched but power is limited, Finder’s 67 Series 50A, high capacity PCB relay efficiently minimises coil power dissipation.

The relay has a high continuous current contact rating of 50A, and peak current of 150A (5ms), providing two and three pole NO double break contacts.

Developed for inverters with DC inputs up to 1500V and AC outputs up to 690V, and with a 3mm or 5.2mm contact gap according to VDE 0126-1-1, EN 62109-1 & 2 regulations, the 67 Series satisfies the arduous requirements of equipment designed to meet the increasing demand for solar energy, particularly in remote locations and at high altitudes (up to 4,000m above sea level).

The relay is also suitable for use in photovoltaic inverters, battery-operated or portable systems, domestic appliances and for 3 phase motor loads up to 7kW.

The Energy Saving Mode feature allows for coil operation in ambient temperatures up to 85C with minimum holding power of just 0.17W

The added air circulation provided by the 1.5mm stand-off between the relay and PCB aids temperature regulation.
