NB90-12S-S-A Applied To Photovoltaic Small Size High Sensitivity 12V 50A Relay
12V 50A Relay Introduce:
The relay is an electrical control device, which can give a specified input quantity and keep it for a long enough time so that the controlled quantity will undergo a predetermined step change in the electrical output circuit. When the input volume drops to a certain level and maintains for a long enough time, it returns to the initial state.
12V 50A Relay Features:
1. High load switching capability: 40A;
2. 2500VAC&4000VAC is available for dielectric strength between contact and coil;
3. Coil insulation grade Class F;
4. Contacts forms NO, NC&SPDT;
5. Dust-proof&Sealed type;
6. Complies with RoHS-Directive.
