SCP Solid State Relay | Emtech Solution

SCP SSR

SCP Solid State Relay

Salient Features :

Advantages :

Contac less Logic Relay with Switching Function Performed by Semiconductor Device.
True Zero Voltage turn ON/OFF.
Input Output Isolation 2500VA.
Virtually Free Electromagnetic Interference and Radio Frequency Interference.
No Moving Contacts So No Acoustic Noise.
Dustproof, Immunity to Humidity, No effect of Alkaline / Acidic Atmosphere.
High Speed And High Frequency Switching.
Shock And Vibration Resistance.
Longer Life Due to Infinite Number of Switching.

Precaution :

For Load Current More Than 3Amp External Heat sink is Must.
Apply Heat sink Pest On the Base Plate of the SSR Before Mounting it on External Heat sink.
Fast Acting Fuse Require For Protection Of SSR.
SSR Rating Should Be More or Equal to Maximum Jerk Current of Load.
For Additional Transient Over Voltage Protection Add MOV.
Do Not Check SSR by Meter OR Continuity Tester. Otherwise, It will Always Shows OPEN.
