100v／10mA regulated voltage power supply circuit

Published:2011/4/20 1:17:00 Author:muriel | Keyword: 100v, 10mA, regulated voltage power supply circuit | From:SeekIC

Thecircuit has two functions that areno-load protection and shorttime short-circuit protection. If you want to allow short-circuit fora long time, it must increase the PCM of theresistance R1 and R2, such as R1=1.2KΩ, 20W; R2=220Ω, 4W. The main technical data: output voltage:U2=100V output current:I2=10mA input voltage:U1=120V~180V Radiator thermal resistance:Rthk=20grd/W output voltage variable quantity: When input voltage U1=120V~180V and nominal load, ΔU2=1V When input voltage U1=120V~180V andno-load, ΔU2=1.5V When output current I2=0mA~10mA (U1=constant), ΔU2=1.5V ambient temperature θu=0°C~60°C, ΔU2=150mV/grd
