 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 […]
