EXPLANATIONS OF TERMS
• SSR (Solid State Relay)
Composed only of semiconductor parts, SSR is free from arc discharge or chattering which is typical with electromagnetic
relays. It features excellent characteristics against vibration, physical impact or other environmental conditions.
• Zero-Cross Function
SSR with zero-cross function turns on when AC power voltage is near zero, creating delay of switching when input is provided in
the middle of an wave cycle, thus limiting transient switching noise voltage and rush current.
Specifications are subject to change without notice.
