Crydom solid-state relays are UL 508 recognised for motor-control applications
Crydom
Lifeplus ED solid-state relays
Crydom’s Lifeplus ED series of AC and DC output-pluggable solid-state relays are UL 508 recognised for general-purpose and motor-control applications such as motors, solenoids, heaters and lamps, and are compliant to IEC 62314 LC-A resistive and LC-B inductive application requirements.
According to the company, the relays can be used by electromechanical relay users as a direct replacement for traditional 12 x 29mm EMRs with Crydom’s Solid State Relay Technology.
Crydom claims that solid-state relays offer substantial performance advantages over traditional EMR switching solutions in many applications, including greater life expectancy (more than 100 million operations), contactless high-speed switching eliminating contact bounce and resulting electrical noise, precise logic-compatible control inputs, acoustically silent operation and high vibration resistance.
AC outputs incorporate Crydom’s Back-to-Back SCR technology, while DC outputs utilise high-efficiency FETs, both technologies resulting in the lowest possible on-state power dissipation and high surge-current ratings, the company claims.
