DC TO DC Solid State Relay
 

DC TO DC Solid State Relay

dc to dc solid state relay

Product Specification

DC to DC Up to 40 AMP PANEL MOUNTED SSR

Salient Features:

  • RDS (ON) Has positive temperature co-efficient which aids in paralleled power MOSFET device And Negative temperature co-efficient of trans conductance. So less susceptible for thermal Runway.
  • Power (PD) increase with case temperature increase.
  • Junction temperature increases with rDS will increased.
  • Switching speed are inherently faster.
  • No need to derating power handing capacity.
  • Turn ON/OFF time more than 10 mili second than
  • Across the load suppression diode require for inductive load.
  • Input LED indication/Output off led indication
  • N/O configuration only.
  • Input-output-body lsolation2.5KVA
  • Glass filled nylon

Advantages:

  • Contac less Logic Relay with Switching Function Performed by Semiconductor Device.
  • 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.
  • 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.

Application

  • Microprocessor Based Control.
  • Traffic Signal Controls.
  • ON / OFF of Solenoid Valve.
  • CNC Machine Control.
  • Switching of Contactors. 
  • Medical Equipments.
  • Business Machines.
  • Primary Transformer Control. 
  • Photography Process Equipments.
  • Automatic Vending Machine.
DIFFERENCE OF POWER MOSFET AND TRANSISTOR
POWER MOSFET TRANSISTOR
High speed on/off (high frequency) Low speed on/off
High power capacity Low power capacity
Voltage drop across power MOSFET is less Voltage drop across transistor is more
Size of heat sink less Size of heat sink more
