UNIT SSR Solid-state relays are different from traditional electromagnetic relays in that their switching life are much longer than that of electromagnetic relays. With integrated MOC3043M optocoupler isolation and zero-crossing detection,It supports input 3.3-5V DC control signal, and control output single-phase 220-250V AC power.
UNIT SSR are controlled by power semiconductor devices, with microsecond on/off speed and built-in over-current protection. Extensively used in lighting control, CNC machine tools, etc., where frequent on/off lines and fast response are required.
Note:
1. Please be careful when using high voltage AC loads, and do not operate with electricity.
2. This relay is for AC loads only.
Advantages over mechanical relays:
1.Faster on/off speed and no physical contact wear.
2.Completely silent operation.
3. No electrical sparks for use in complex environments.
4.Long lasting
5 .Compact size
