Wuxi Gold Control Technology Co., Ltd., was founded in 1992, has been a private high-tech manufactory, specializing in the research and production of PCB mounting solid state relays, AC/DC SSR, SSR heat sink, voltage regulation controllers, etc. Most products have passed international certificates such as NSF, UL, CE, CUL, RoSH, ans so on. Our various types of heat sink can meet all your requirements. For example, we have solid state relay in one heatsink like omron, dual output, as well as three phase SSR like Crydom.

The SSR is a series of single-pole, normally open, solid state switching devices with no moving parts, capable of tens of millions of cycles of operation. A control signal causes the heat sink to switch the AC load ON or OFF just as a conventional mechanical contact switch does but with none of the problems associated with moving contact relays, such as corrosion, pitting, arcing, radio frequency interference (RFI) and bounce. Therefore, the solid state relay is able to sustain a much longer life.

Our SSR solid state relay heat sink is designed around a pair of SCR's mounted on a heat-spreading metal base to eliminate thermal fatigue failures. To dissipate the heat developed naturally in a solid state relay due to a nominal voltage drop across the device, it must be mounted on a Finned Heat Sink (FHS), or on a metal plate of adequate size.
