This is bench power supply circuit for multi purpose usageā¦
This bench power supply features three solid-state DC power supplies. The first supply gives a +1.5 to +15 volts at 1 ampere. The second supply gives a -1.5 to -15 volts at 1 ampere. The third has a fixed 5V at 3 amperes. All? DC supplies are fully regulated. A special IC circuit keeps the output voltage within .2V when going from no? load to 1 ampere. The output is fully protected from short circuits. This supply is ideal for use in school labs,? service shops or anywhere a precise DC voltage is required.
Take a note that based on the diagram, this circuit require 120V AC to 17V AC Center Tapped Transformer. If your country use 220V AC home electric, you MUST change the Transformer 220-240V AC to 18V AC Center Tapped Transformer.
Power Supply Specification:
Output Voltage : 1) 1.5-15VDC @ 1A (at 120V input) : 2) ?1.5 - ?15VDC @ 1A : 3) 5VDC @ 3A Output Regulation : 200mV each supply Line Regulation : 100mV each supply Ripple : Max 5mV RMS Current Protection : 1A limit 2-15VDC : 3A limit 5VDC Short Protection : 1A limit 2-15VDC : 3A limit 5VDC Output Impedance : .025W each supply
