Cause sterility new New design, simple and versatile electronic load! Automatic memory function with all parameters, is well suited for automated assembly of the power adapter aging cabinet The latest version, slightly larger size and upgrade the fan into the 5020 high speed dual bearing fan, higher cooling redundancy, more suitable for long hours! Note: This product is a professional testing equipment, requiring the user must have some basic electronic (example: Users should understand what is the meaning of the voltage and current capacity Ah , etc. ), or you may be unable to properly use the device, possibly mishandled cause unnecessary damage caused by the test device loss! PPower supply requirement: DC12V voltage ( actual voltage 11-14V) current is not less than 0.5A of power, the power be displayed inappropriate Err6 Note: The default power adapter is not included Operating modes: single mode constant current (CC) Discharge current : 0.20-9.99A stepper 0.1A or0.01A Discharge current maximum error : 0.7% -0.01A The maximum capacity test error : 0.5A 2.5%, 2A 1.5%, 5A and above 1.2% Offline ( termination ) Voltage Range : 1.0-25.0V stepping 1V or 0.1V Discharge voltage : 1.00-30.00V The maximum voltage measurement error : 1% + - 0.02V it can open 9.99A 6V and 20V maximum at the only open 3.00A) Highest battery test statistic : 999.9Ah or 9999Wh, achieve value stop testing (first value to those who stop condition) Board size: 60W 100mm x 70mm x 57mm (fan prominent board about 12mm) Positioning hole locations : 60mm x 88mm, diameter 3.2mm 5mm pedestal already installed Fan control : intelligent fan control (according to the radiator fan can be infinitely variable automatic temperature) Protection: Overheat protection "otP", transient overpower protection "oPP", overpressure protection "ouP", reverse polarity protection, power supply voltage abnormal protection colour: as shown Material: PCB Package Contents: 1 x Capacity Tester Only the above package content, other products are not included. Note: Light and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
