2.3 Performance characteristics
☆ Specification: Output voltage 0-rated voltage, output current 0-rated current
☆ Voltage and current preset: The panel comes with preset buttons that can preset voltage and current values
☆ Stable voltage and current: The voltage and current values are continuously adjustable from zero to the rated value, and the stable voltage and current are automatically converted
☆ Overvoltage protection: The overvoltage protection value can be set, and the output will automatically turn off when the output voltage reaches or exceeds the overvoltage protection value
☆ Memory function: With memory function, it can save preset voltage, current, overvoltage protection values, etc. when turned off
☆ Intelligence: RS-485/RS-232 communication interface, using MODBUS RTU protocol, can achieve remote control of computers and PLCs
☆ Voltage compensation: Connect external voltage sampling lines to reduce voltage errors caused by long output wires, and achieve flexible switching of voltage sampling signals (optional)
☆ Analog signal: 0~5V, 0~10V, or 4~20mA analog quantity can be selected to control the power output signal and read the power output signal (optional)
Protocol format
1. Serial port
Data bit: 8 bits, stop bit: 1 bit, check bit: none, baud rate: 9600, default value.
2. MODBUS protoco
This device uses MODBUS RTU communication format.
This device supports instruction codes: read multiple writable register instructions (0x03), read multiple read-only register instructions (0x04), write multiple register instructions (0x10), and write single register instructions (0x06).
Reading and writing multiple registers can only read and write registers with consecutive addresses at once. If you need to write a register, you can use the Write Multiple Registers instruction and write the number of registers to 1
The register address is a number with a length of 16 bits per word, as detailed in the table below.
The register content is a number of 16 bits per word, which is unsigned by default.
This device only supports fixed point numbers, and the data related to voltage and current actually represents the number of words according to the displayed resolution. Customers need to change according to the displayed decimal places. Please check the display on the panel after the power is turned on for the decimal places of voltage and current. The decimal places are generated according to the power specifications and cannot be changed after leaving the factory.
For example: 50V300A power supply, displayed in 4 digits, with 2 decimal places for voltage and 1 decimal place for current. Voltage 5000 represents 50V, current 3000 represents 300A; 1000V10A power supply, 5-digit display, 1 decimal point for voltage and 3 decimal points for current. A voltage of 500 indicates 50V, and a current of 3000 indicates 3A.
