1. The symbol on an instrument indicates that the user should refer N to the operating instructions located in the manual About IT6720 With widest voltage and current range IT6720digital DC power supplies are applied in many fields With max power 100W and output adjustable in 60V 5A auto control voltage current slew rate power rate up to three times rapid than other similar products a unit can replace three models 60V 1 6A 32V 3A 20V 5A reduce your repeat investment Example When you set the output voltage as 60V because the max power of IT6720 is 100W so the max output current is 100W 60V 1 6A Power When you change the output voltage to 30V 100 the output current is 100W 30V 3 2A y Calculate according to the above way when the output voltage is 20V the output current should be 5A but as the max rating current of IT6720 is 8A so the final max output 1 2 3 4 5 current is 5A IT6720 output curve Function E Fully digital control E High resolution 10mV 1mA in Full range E Low ripple and noise E Software calibration E Bright and easy to read display VFD Constant current and constant voltage output E Selectable remote control keypads E High reliability OVP OCP OTP protection E Output on off control Best performance price ratio E Storage for 4 100 pre2. mode set the voltage current value to be stored CursorlAl D will wink together Press to save it In the normal working Press any key in Recall operation IT6720working in the shortcuts mode Press any key in recall the preset voltage current value which has been stored When the power supply is on recall operation that mea parameters from the store group Press any key of E recall the stored parameter When the power supply is o they only can be used with function CC are disabled to exit recall call operation key Press Faulty disposal If the outputs is disabled 1 Check whether voltage and current settings are zero if so reset voltage and current value 2 Check whether the indicator OFF is lit on if so press outputs 3 Check whether the indicators are lit on if so please reset according to the mentioned OVP OCP OCP means If the keypad is disabled check whether the indicator is lit on if so unlock the keypads as the above means 6 Specifications _ Specs Specifications Output Rating Load Regulation Line Regulation Programming Accuracy Read back Accuracy Ripple Dimension Weight Voltage Current Power Voltage Current Voltage Current Voltage Current Voltage Current Voltage Current W H D Net T6720 0 60V 0 5A 100W lt 0 01 3mV lt 0 01 3mA lt 0 01 3mV lt 0 1 3mMmA lt 0 05 10mV
