Relay features 'arc blowout' for higher dc voltage switching

13 March 2012

Willow Technologies is now supplying the DG38L PCB power relay from Durakool. Featuring a magnetic arc blowout, enabling the relay to switch 50% higher dc voltage than similar relays (in excess of 24V), the DG38L is able to deflect the arc away from the contacts as the relay opens, thus extinguishing the arc. Moreover, the shielded fast-on blades for power terminals avoid the the PCB from having to carry high currents and voltages.

Typically, this style of relay is only able to switch 30A at 24Vdc/240Vac. The DG38L can handle voltages up to 80Vdc (as an option) or 45A at 28Vdc as standard.

The relay measures a compact 32.2 x 27.5 x 28mm and is suitable for switching dc motor loads, such as winches, stair lifts, CNC machines, garage door motors and solar energy controllers.
