 Regulated DC power supply variable output 0-60V 1A

Friday, December 7th, 2012

This 0-60V variable voltage regulator power supply circuit is designed to supply the output voltage to zero volt, without a transformer with a secondary winding two coils. We can use the well-known IC is LM723. Or if you want to pressure is higher, use a number L146. Although is known less. But enough buy them. […]


 0-70 Volt 2 Amp DC variable power supply

Tuesday, September 18th, 2012

When you want to adjust the dc power supply circuit voltage up to about 70V. But the “Cheap adjustable 0-30V 2A Laboratory DC Power Supply” project can fine maximum voltage is 30 volt only. We need to add more 40V. You do not look difficult. We can adapt very easily, with the addition of just […]


 Stabised Current Battery Charger by LM723

Saturday, November 1st, 2008

Normally battery Charger Circuit, will use the way gives Stabised Current or stable current. For this circuit also the integrated circuit LM723 and electronic parts a few with follow the circuit appraise R1 = 11ohm for fix current at 60mA. We can seek the value R get from R = 700/I and The transistor 2N3055 […]


 Variable Regulator 0-30V 5A by LM723,CA3140,2N3055

Wednesday, October 3rd, 2007

This is circuit Variable Regulator power supply,Output voltage 0-30V and Current 5A max. Use IC LM723 is a voltage regulator designed primarily for series regulator applications. By itself, it will supply output currents up to 150 mA I so use Transistor 2N3055 X 2 for Booster current to 5A. IC CA3140 for Control Current and […]
