ANGS series grid simulator power supply is specially developed for photovoltaic, wind energy and other new energy industries, and is suitable for inverter testing and verification. The power supply adopts FPGA digital control technology, and the inverter test process can be fully intelligent; it has a sine wave output mode and multiple harmonic superimposed output modes, single-phase, two-phase or three-phase low (zero) voltage ride-through, which can be fully simulated.
Features:
1.Adopt FPGA digital technology, realize intelligent inverter testing process;
2.High performance low (zero) voltage ride through;
3.Voltage and frequency can be set as complex programming such as Step, stage or varations, overvoltage/undervoltage, over-frequency/under-frequency test;
4.Harmonic mode, can be superimposed 2 to 40-th harmonics;
5.Three-phase Unbalanced mode, adjustable three-phase voltage and three-phase phase difference, Realize three-phase Unbalanced test;
6.High voltage DC output. Loop test combining PV inverter;
7.Operating in over current shock( up to 3 times of rated current) within 2s,strong load capacity;
8.Complete measurement function: voltage, current, peak current, frequency, active power, apparent power, power factor, voltage crest factor;
9.Online monitoring: IGBT temperature, transformer temperature, fan speed, input voltage and other parameters in output state;
10.Operating data recorder: Automatically record the power status, alarm code etc. in case of alarm, greatly reducing maintenance time;
11.Automatic fan speed adjustment according to the temperature of the power supply, quiet;
12.Lock key, user-friendly design, automatically locking after no-operation for 5 minutes to prevent misuse;
13. Combination cabinet, 8" large-screen color LCD;
14.Standard RS232, optional RS485, GPIB, Ethernet port or analog control mode;
Applications:
1. Grid simulator power supply, the solar cell simulator and power analyzer forming the inverter test system
2. Grid simulator power supply output high-voltage DC, conducting loop test combing with the inverter
The DC output terminal of ANGS series Grid Simulator Power Supply is connected to the DC input terminal of the inverter. The DC output terminal of the inverter is connected with the output terminal of the Grid Simulator Power Supply in parallel to form a loop test. The energy flows in the loop, saving equipment investment for some specific tests.
3. Low (zero) voltage ride through
4. Programmable output (step, stage, varations) for over-voltage/under voltage and over frequency/under frequency testing.
5. Harmonic mode
6. Three-phase unbalance test
7. Large-size color LCD, digital key input, knob operation
