Feedback AC power supply A7000 series

Brief Introduction
? A7030 is a feedback AC power supply, with an input of three-phase AC 380V, 50Hz power supply and an output of voltage L1-N-L2: 0-300V, adjustable frequency 47-63Hz. It has the characteristics of high voltage stability, strong load capacity, high efficiency, and small size.
? The power supply uses ARM+FPGA as the control core, directly synthesizes SPWM waveforms, and is inverted by power IGBT and coupled output by transformer. Built in voltage and current compensation circuits, fast response speed. The voltage and frequency can be accurately set by digital buttons. The output parameters are directly A/D sampled and processed by the internal circuit.
? The 4.3-inch LCD screen can display parameters such as frequency, voltage, current, power, power factor, etc. Output high-speed acquisition calculation output parameters, can export output data and waveforms.
? 5 sets of fast storage memory functions, which can quickly call commonly used voltages and frequencies. It has a built-in universal programming loop function, which can set 35 different voltages and frequencies for sudden and gradual change tests according to the set time, and can loop 9999 times. (Optional)
? Rich interface configuration, RS232, RS485 and other interfaces, as well as a comprehensive command system, multiple baud rates or address options, make it easy to control multiple power supplies with one RS485 port. GPIB and CAN interfaces can also be optionally selected for application in special fields.
