RS-485 power supply unit PADS

The energy feedback type programmable AC/DC power source with energy feedback unit equipped functions of voltage adjustable, frequency adjustable, harmonic controllable, low voltage ride through simulation etc. The programmable AC&DC power supply unit is an ideal tool for research and development of photovoltaic/storage inverters, converters, rectifiers, DC power supplies, DC-DC converters, UPS/EPS, motor/generators, power transformers, chargers/piles, batteries, electronic products, etc. It can be used in the production commissioning, factory inspection, laboratory electrical characteristics testing, authoritative organization identification testing and other fields. ● With energy feedback function, it can provide 100% rated power recovery ● Output frequency 0-100Hz, step size 0.01Hz ● Internal waveform synthesizer, can realize any sub-harmonic superposition function (up to 50 harmonics at maximum) ● Equipped over-current, over-voltage, over-heat, over-load and short circuit protection etc. ● A variety of communication interfaces, including RS485, RS232, and Ethernet ports. ● Can be connected by shielded twisted pair cables and network cables, Modbus protocol is available. The power supply output is controlled by the host computer software, and the software can run on Windows XP and Win7. By adjusting the amplitude and phase of the output voltage, voltage disturbance, frequency,disturbance, harmonic disturbance, three-phase unbalanced disturbance, fluctuation and flicker disturbance performance can be tested.
