Power Supply source +5 Vdc +12 Vdc

July 28th, 2012 by psu | No Comments | Filed in Regulated Power Supply

12VDC & 5VDC power supply sourceThis power supply circuit shows a steady source of continuous power supply combined with an output of +5 VDC and +12 VDC to ground, it is estimated for designing a current of about 900mA Max, enough to power any digital circuit with a relay output,that must be taken into account is the cascade design makes total consumption is the sum of the currents provided by the two outputs. Please note that the regulator should be equipped with a heat sink.

57V variable power supply up to 1.5 A

May 10th, 2012 by psu | No Comments | Filed in Regulated Power Supply

57 V variable power supply circuitIn each workshop you must have a source that is able to provide each current and voltage in a quite acceptable range of possibilities. This variable power supply device goes beyond the conventional power supply source (which rarely exceed 24V output) gives the maximum 57V with 1.5A current.

35V adjustable power supply 1.5 A

April 28th, 2012 by psu | No Comments | Filed in Regulated Power Supply

One of the most needed instruments in electronics lab is adjustable power supply, allowing you to feed each circuit is tested or constructed for the required voltage and current. 35V power supply adjustable 1.5 A
The adjustable power supply circuit shown here is just a linear power supply, a bridge rectifier and filter capacitor that it attach series voltage regulator. Furthermore, here was provided by a pair of fixed instruments that allow us to know at any time the voltage given in the output and load current used.

15 ampere adjustable power supply

April 24th, 2012 by psu | No Comments | Filed in Regulated Power Supply

This adjustable power supply circuit provides an output voltage source which can be adjusted between 1.5 and 15 volts and give 15 amps current.15 A adjustable power supply
As is shown in the wiring diagram the 15 A adjustable power supply provides similar amount of current through the parallel work of four power transistors, which must be mounted on a good heatsink. The voltage adjustment is performed in integrated LM317, which also must be dissipated mechanically.
