Product introduction of [High Power Programmable DC Power supply]

150V100A forming power supply is a voltage-stabilized and current-stabilized switching power supply. Advanced high-frequency pulse width modulation (PWM) technology is adopted to realize voltage stabilization and current stabilization by adjusting the pulse width of the conversion circuit. This power supply has the functions of high stability, low ripple voltage, long continuous time, over-voltage, over-current, overheating, and phase-lack automatic protection to cut off the output function, so that the output voltage and current can be kept reliable and stable under any circumstances. The whole system is controlled by Panasonic PLC Programmable Logic Controller (FP-X C38AT), which is measured by PLC self-embedded two-way A / D conversion module and two-way D / A conversion. All the parameters and the working state of the instrument are displayed and set on the 10-inch color touch screen (MT6103iP) in Taiwan. All kinds of parameters are cut off and memory, and the user-friendly interface is easy to operate.
