Solid State Relay, load current 25A, 70-280V AC to 24-480V AC, with LED indicator, zero-crossing switch, built-in RC, especially suitable for frequent switching occasions and other harsh environment like corrosive, moist, dusty, etc.
|On-state voltage drop
|Off-state leakage current
||2500V AC (1min)
||500МΩ with 500V DC
||Install heat sink or fan for cooling.
Tips: Solid state relays' advantages and disadvantages
Solid state relays work reliably and have a long life, no noise, no spark, no electromagnetic interference, fast switching speed, strong anti-interference ability, and small size, impact resistance, vibration resistance, anti-explosion, moisture proof, corrosion resistance, compatibility with logic circuits such as TTL, DTL, HTL. They can directly drive high-current load with tiny control signals.
The main disadvantage is the existence of on-state voltage drop (corresponding cooling measures needed), off-state leakage current, common use in AC and DC conditions, fewer contact sets, as well as poor indicators including overcurrent and overvoltage and voltage rise rate, current rise rate, etc.
