High-Precision Programmable AC Power Source with Four Output Modes: AC/DC/AC+DC/DC+AC

High-Performance Design:

• Manufactured using Linear methods, featuring remote voltage feedback to ensure the test point voltage matches the set value

• Strong impact resistance, capable of easily driving motors, compressors, and other same-power impact loads

• 4-digit LED display for measuring voltage, current, frequency, power, or power factor

• Adjustable voltage and frequency during output state

• Lock key function, quick key input, knob operation

• Standard with RS232 communication interface, optional RS485/GPIB communication interface or analog control method

• Features power-off memory function, automatically remembering the last output parameters

• Automatic high/low voltage switching: 0-150V, 150.1-300V auto switch, or lock at 1-300V high range

User-Friendly Design Highlights of the Frequency Conversion Power Supply:

• Test data security with digital password lock, preventing accidental modification of important test data

• Humidity and temperature detection function, intelligent cooling and dehumidification design, providing a safe and comfortable working environment for users

• Real-time monitoring by multiple sensors on the machine, displaying normal operation codes and fault codes on the screen for comprehensive control of machine status

• Parameter calibration is completed through open-source software, different from other power supplies that require adjustment of potentiometers and adjustable resistors on the circuit

• Wide voltage and frequency adjustment range, using a rotary encoder combined with shift keys for adjustment, independently displaying three-phase phase voltage and line voltage

• Large 7-inch touch screen displaying various parameters including voltage, frequency, power, power factor, current, peak current, temperature, battery level, time, phase angle, impedance value, and real-time current/voltage curve graphs
