irhapsody Relay 200A, 12V Continuous Duty SPST 4-pin High Power Relay
- Our coil power is 1.8W, and coil resistance is 80ohms. It is more reliable than 2.4W (60 ohms) and 4.8W (30 ohms) relays on the market
- Large capacity, high current carrying capacity, heavy-duty make/break relay. But never go beyond its capabilities, try to stay 10 to 15% below what the rate is for
- Rated voltage: 12vdc; Pickup voltage: 8v; Dropout voltage: 1.2v; The size of the round stud terminals: M6/6mm
- Matching specifications: The coil voltage and contact current must be consistent with the circuit (for example, a 12V relay should be used with a 12V circuit)
- Overload protection: The load current of the contacts must not exceed the rated value of the relay; otherwise, it may cause the contacts to burn out, stick together, or even catch fire
