dc_to_ac_solod_state_relay

DC to AC PANEL MOUNTED SCP SSR


Salient Features:

  • Panel mount with short circuit protection solid state relay
  • Opto isolation 2500 VAC
  • Gets protected against load short circuits
  • Zero voltage turn on
  • Reverse voltage protection
  • TTL compatible (sink mode)
  • Out put NO configuration
  • Inbuilt snubber
  • Chassis mountable
  • Higher load cycle resistance
  • Higher thermal cycling capacity
  • High fusing current
  • Normal/ Fault indication
  • SSR PROTECTED Without M.C.B
  • We are make all type of short circuit protection SSR

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.
