The blue-screen high-precision programmable linear power supply uses a 122 x 32 LCD display, which can comprehensively display the status of the power supply, high resolution and high accuracy, resolution: 0.1mV/0.1mA (5 digits), 0.01mV/0.01mA (6 digits) ); using high-quality pure copper toroidal transformer with small ripple and high stability; using high-quality pure copper toroidal transformer with small ripple and high stability; standard 2U height chassis, which can be installed side by side in the cabinet. Convenient and fast operation and setting interface, high-speed adjustment knob and digital key input; built-in buzzer as a reminder or warning; 100 sets of setting storage and recall functions, which can store/recall 100 sets of voltage and current data; remote sensing The voltage drop of the load line is compensated, and the precision is higher. Overload, reverse polarity protection, overvoltage protection, overcurrent protection, overtemperature protection, one-key lock function, effectively prevent misoperation; standard RS232 interface, support SCPI and MODBUS programming instruction set; widely used in product aging maintenance, Battery charging, experimental testing, production testing, electrolytic plating and other industries.
