Product Introduction:
The economic program-controlled DC electronic load series can measure up to 360V, which can be widely used in non isolated LED driving power supply, power transformer, charger, switching power supply, battery and other industries, such as online testing and laboratory testing fields.
The display of the instrument is intuitive, comprehensive and easy to operate. Its perfect functions of constant voltage, constant current, constant power, constant resistance, remote measurement, short circuit test, battery test, dynamic test and upper computer software control enable you to obtain the multi-purpose benefits and convenience of one computer.
Main features:
■ Maximum 360V test voltage to meet the test requirements of non-isolated driving power supply
■ Fixed Current, Fixed Voltage, Fixed Resistance, Fixed Power Mode
■ Dynamic measurement mode
■ Battery Testing Mode
■ List Automated Test Mode
■ Standard RS232C interface
■ Remote Testing Function
■ Over Voltage, Over Current, Over Power, Over Temperature Protection
