Programmable DC Power Supply

With high precision, high dynamic, and wide-ranging output of general programmable DC power supply, the ActionPower PVD series products can be used in photovoltaic inverter testing, solar panel simulation, and common electrical power testing. This photovoltaic simulator has a built-in independent high-precision voltage and current measurement system that is easy to program and takes DC voltage supply test instruments to the next level.

Features

1.High Dynamics

The solar panel simulator PVD model delivers dynamic performance in the order of 500μs to 1ms, capable of simulating

field abnormal conditions in the lab.

2.High Accuracy

//Up to 6½ digit measurement system; voltage and current accuracy up to mV/mA level.

3.Digital matrix parallel system

The solar array simulator PVD model is equipped with a matrix, high-speed fiber-optic digital parallel system that can

combine up to 100 units into a complete system, creating a total power of up to 3000 kW. After parallel installation,

the performance of the system is still equivalent to the standards of a single machine.

4.Function Generation

All models of PVD series can superimpose sine, triangle, pulse and square waves on the DC output; the frequency

resolution of the expected waveform output waveform is 0.01, up to 10kHz; the DC component value of the expected

output waveform, with a resolution of 0.001; to meet the test article for DC voltage ripple adaptability testing.

5.High power density: 3U/30kW

The PV array simulator PVD model has the highest power density and feed-back efficiency compared to similar

products, with up to 30kW of power in a 3U volume and a light weight of 35kg.

6.Function Programming

In addition to the traditional List, Wave, Step and Advanced programming functions, the high-power DC power

supply PVD model also supports function editing, sine wave, pulse wave, triangle wave and custom wave programming

functions to meet the individual needs of product development and testing, regulatory testing and certification,

production line testing and quality control.

7.Four output modes

The off-grid solar system simulator PVD has four modes of constant voltage (CV), constant current (CC), constant 

power (CP) and constant resistance (CR) indication, of which the CC, CV and CP modes can be switched

automatically according to the formula P=UI.

8.SAS model

The SAS solar cell simulator function can accurately simulate the output I-V characteristic curve of solar panels

with built-in SAS models from EN50530, Sandia, CGC/GF004, CGC/GF035, and other standards for static and

dynamic MPPT of PV inverters testing.
