Overview

Our Dc Power Relay is widely used in various scenarios, such as air conditioner, water heater, rice cooker, computer, fax machine, etc. Its shell is made of high-quality materials with good thickness and smoothness. The contact is made of composite silver material, which makes the suction more accurate and has a longer service life. It has all copper enamelled wire, exceeding the national standard full turns, all copper enamelled coil, more stable current transmission and safer use.

Our company is the source relay manufacturer with strong strength and quality assurance. The produced relays have served thousands of partners in China, and have been successfully sold to foreign markets and won wide praise. Our Dc Power Relay plays the role of automatic regulation, safety protection and conversion circuit in the circuit.
