Feature: 1. Multi-Information Display: 2.8-inch TFT LCD display many information at the same time. Such as voltage (output voltage set value and actual output value), current (output current set value and actual output value), actual output power, cumulative execution time, channel Output status. When the actual current exceeds the preset current value,the power supply automatically switches to CC mode to protect the circuit. 2. Multiple conservation functions: DC power supply is High quality. Multiple protections include limit current conservation, thermal conservation, voltage overload conservation, short circuit conservation, over power. This considerably improves its efficiency and durability 3. Convenient USB port design: The power supply can not only be used as an adjustable power supply, but also has a 5V/1A USB output port that can charge your mobile phone and a back USB device communication port to update firmware and PC software controlled. 4. Adjustable Power Supply: Constant power design, wide application range, provides flexible con figuration of higher voltage and cur rent within the rated power range. Programmable Power supply with Memory Key which have 4 groups of Memory shortcut parameters for quick output.List waveform editing output editable 10 groups of timing output. 5. Compact and Lightweight: The measures of the variable lab power supply is only 3.2*8.9*5.6 inch and the weight is only about 3.5 pounds, which saves more space on your workbench and is convenient for you to carry when you need it.
