Song Chuan Relais 110/510 for Solarinverter

The 110 series is a new, innovative, powerful single-pole miniature relay with one NO contact and a contact gap> 1.5 mm. The compact design (dimensions: 21.5 x 16 x 20.6 mm) saves 35% board space compared to comparable relays. The max. switching current is 26A / 250VAC at 70 ° C and 22A / 250VAC at 85 ° Celsius.

The Series 510 (Dimensions: 51.5 x 35 x 39 mm) is a two-pole power relays for high contact currents. The maximum switching current for version 510 is  2 x 35A / 250VAC at 85 ° C. The version 510H (High Power) is designed for currents up to 2 x 54A / 250VAC at 85 ° C. The contact distance is in the range 510> 2mm. A contactor relays can be replaced with the series 510.

To meet the marketexpection, the holding voltage could be reduced by 100ms by more than 50% of nominal voltage for both series.

Both series have a new contact material with a smaller, used throughout the life of stable contact resistance. Thus the self-heating of the relay is reduced. This is a great advantage for the manufacturer of solar inverters, since the temperature of entire unit is reduced.
