Quick response and high accuracy regulation attributable to using of linear
One-key recall for 9 different voltage and frequency
Optional GPIB and RS-232, RS-485 interface
Over voltage, over current, over temperature and short circuit protection
Constant power mode
Numeric key for data setting
Under output rated power, voltage and current can users freely combine the required settings; Constant voltage and current
output depends on the setting of output voltage and current, size of resistance. As shown in the following: Curve1 and
Curve represent two resistances of different load, when Curve1 and Curve are intersected, power supply is working under
constant current(CC) mode, yet Curve2 and Curve intersected, it under constant voltage(CV) mode.
Users can judge the status of resistance by simple calculation.
If Vset=Setting Voltage, Iset=Setting Current, then Rset (Setting resistance)=Vset/Iset;
If there is real resistance RL=Vo/Io,
RL>Rset, power supply works under constant voltage.
RL<Rset, power supply works under constant current.
