Power Supply 0-300V DC Adjustable

Power Supply circuits | By: Diagram mania

This is circuit high voltage Power Supply DC Adjustable Voltage 0-300V 100mA max. It is a simple circuit which can provide an adjustable voltage source of 0 to 330 Volt.. The supply is short-ciruit proof: the current is limited to about 100mA. 0-300V power supply schematic: To prevent my high voltage experiments to go up […]

Circuit Power supply Low Volt Regulator by LM317

Power Supply circuits | By: Diagram mania

Circuit 5V Power supply Low Volt Drop out Regulator by LM317 When want 5VDC power supply but the level is voltage input low 5.1V just. Be possible difficult that can we come to see this circuit Circuit Power supply Low Volt Regulator by LM317. Be character circuit low Volt drop out regulator have Volt drop […]

48 VOLT PHANTOM POWER SUPPLY By TL783C

Power Supply circuits | By: Diagram mania

This is a simple 48 V regulated linear power supply design that will provide up to 60 mA of current. This circuit is based on the Texas Instruments TL783C high voltage adjustable linear regulator IC, because this device will provide short circuit protection for an input to output differential voltage of up to 125 V. […]

Power supply regulator for Bicycle

Power Supply circuits | By: Diagram mania

This is a regulator for a 6V/3W bicycle generator system. The purpose is to switch to rechargeable batteries when the generator is idle. In addition, the device limits the voltage across the bulbs when the generator operates at a high speed. As you can see, the circuit is purely electrical. In the presented design, the […]

Charger battery Lithium Variable current up to 2A by L200

Power Supply circuits | By: Diagram mania

This is circuit Charger battery Lithium Variable current up to 2A by IC L200. I’ve always wanted a fully adjustable current DIY lipo charger (and recently higher output). The L200 datasheet has an LM741 op amp design to achieve this. It works well but has a very non-linear action (worse with a log pot). So […]

Simple DC-DC Converter

Power Supply circuits | By: Diagram mania

Have you ever wanted to build a circuit to run off a single 9 Volt battery only to find you needed levels like +12 and -12 Volts? The thought of multiple batteries might have put you off. Why not use a simple DC to DC converter?Just to prove a point, here’s a DC to DC […]

Converter 3.2VDC to 9V-12VDC ( For Solar Charger)

Power Supply circuits | By: Diagram mania

If you require 9v to 12v output, you will need to add the four voltage-regulating components shown in the diagram below. The voltage-regulation components added, the circuit produces a 9v or 12v output. This arrangement is only suitable if you have a constant, reliable, source of sun as any clouds will reduce the output to […]

Power Supply A fixed Voltage of 6, 9 or 12V, max output 1A.

Power Supply circuits | By: Diagram mania

Power Supply A fixed Voltage of 6V, 9V or 12V, max output 1A. When see the circuit that me will advise this. As a result may think back go to many year , because of the equipment and model old circuit is exceedingly. But I believes in that many you may like. Because be the […]

Simple Fuse Monitor Alarm

Power Supply circuits | By: Diagram mania

  It came to me in a flash. A simple way to see if a fuse has blown without removing it from its holder. Its not often you can design a circuit using just two components, but with just one resistor and an LED this circuit provides visual indication of when a fuse has blown. […]

Linear Regulated Dual Polarity Power Supply by LM317 and LM337

Power Supply circuits | By: Diagram mania

The circuit is fairly standard of a linear supply, and the function of each part can be described as follows: TX1 is a center-tapped transformer which converts the line voltage from 120 or 240VAC to a lower value which can be managed by the filter circuitry. See note 1 for more details. Diodes D1-D4 rectify […]
