Power Supply source +5 Vdc +12 Vdc

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

Dual 12 V 5V power supply 300x135 Power Supply source +5 Vdc +12 VdcThis 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 variable power supply circuit 300x100 57V variable power supply up to 1.5 AIn 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.

Variable 4 A/25V Power Supply

May 2nd, 2012 by psu | No Comments | Filed in Regulated Power Supply

All workshops or laboratories must have a power supply for general purpose that can supply voltages and currents.
adjustable 4 A 25 V power supply 300x123 Variable 4 A/25V Power SupplyThis time we get a adjustable power supply with output voltages between 1.2 and 25V the maximum current of 4A.  This is very useful for laboratory power supply or workshop power supply.

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 300x78 35V adjustable power supply 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 300x166 15 Ampere 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.

Symmetrical regulated power supply and variable 0 to 30V 2A

April 11th, 2012 by psu | 2 Comments | Filed in Regulated Power Supply

Symmetrical regulated power supply schematic 300x220 Symmetrical regulated power supply and variable 0 to 30V 2AThis Symmetrical regulated power supply and variable power supply 0 to 30V 2A circuit does not require further explanation, which is a controlled variable symmetric source, can deliver up to 15V per line (-15 and +15), or up to 30V as a whole, for the consumption of up to 2A, but with some changes could be modified to provide up to 5A ** (or more). Transistors Q1 and Q2 should be installed on a heat sink, as well as integrated LM337 and T LM317 which is in the TO-220 package.

DC power supply 3-30V 3-30V 3A stabilized

February 27th, 2012 by psu | 2 Comments | Filed in Regulated Power Supply

3 30V power supplply 3 A circuit diagram 300x173  DC power supply 3 30V 3 30V 3A stabilizedThis DC power supply circuit diagram is designed as an additional or as a permanent power supply for all general circuits based on a stable DC voltage between 3 and 30V provided that current consumption does not exceed 3A. Of course, this DC power supply can also be used to other purposes. By replacing the trimmer by a potentiometer, it can even be used as adjustable supply unit. A good quality heatsink must be used.
