Variable power supply 3/2A

Variable power supply 3/2A

DC Adjustable Power Supply: This is a 24VDC / 12VDC / 10VDC /5VDC linear regulated adjustable power supply and consists a step down transformer. Output is adjustable by preset on the PCB. External potentiometer can be used for adjusting the output voltage. The output is almost ripple free and can drive resistive and inductive loads. The power supply do not induce any noise. This power supply is ideal for PLC,encoder, controller, sensors, Embedded systems, proximity switches etc. The output is having short circuit and thermal overload protection. This linear power supply is very cost effective. Available in different current ratings as 3Amps/2Amps. The power supply can be used as a 7 AHr battery charger.

Comparison between SM & Linear power supply

Sr.No SMPS Power Supply Linear Power Supply

Output Contains ripples

Ripples are almost absent

2 More components hence more chances of failure

Less components, no chance to fail is rare

3 Complex design so very difficult to diagnose problems even for specialist

Simple design so even ITI /technician can easily repair this

4 Failure of power supply may sometimes lead to damage of costly equipment connected on to it In case of failure the o/p voltage is bridge voltage and that do not exceed o/p Volts+5%

Other voltages (28.0V, 15.0V, 18.0 etc) on demand

  • Due to continuous product development the product supplied to you may look different than the product image in the pdf file.
  • If power supply is to be used as battery charger then customer should inform Q-Log controls about application.
