Compared with the traditional EMR (electromagnetic relay), Solid State Relay, briefly SSR, is a relay without mechanical movement and no moving parts. An SSR is an all-electronic circuit combination component that relies on the semiconductor devices and the electrical, magnetic and optical properties of electronic components for its isolation and switching functions. Solid state relays have the advantages of long endurance life, fast speed, low electromagnetic interference, shock and vibration resistance, etc., and are widely used in control applications in various fields of industry.
Xiamen Kudum Electronics Technology Co., Ltd. is a professional manufacturer for solid state relays and related modules. Kudum's KSA series could replace OMRON's G3MC series and Panasonic's AQG series, which are widely used in home appliances and industrial small load controls, such as air-conditioning indoor, refrigerators, refueling guns, etc. The installation holes of these three product series are the same, and the main parameters are compared in the following table:
Parameters | KSA | G3MC | AQG |
Load voltage range | 24~280VAC | 75~264VAC | 75~264VAC |
Rated load current | 2A | 2A | 2A |
Control voltage | 5/12/24VDC | 5/12/24VDC | 5/12/24VDC |
Max. output voltage drop | 1.5VAC | 1.6VAC | 1.6VAC |
Dielectric Strength | 3000VAC | 2500VAC | 3000VAC |
Ambient temperature range | -30℃~80℃ | -30℃~80℃ | -30℃~80℃ |
