ALC5000 series single/three-phase feedback power grid simulator adopts pure digital PWM rectification technology, SPWM high-frequency pulse width modulation method, advanced direct digital frequency synthesizer (DDS) waveform generation technology, with full back-irrigation function, can input AC The source energy is fully fed back to the grid; the input power factor is high, the grid pollution is small, the output waveform quality is high, and the dynamic response speed is fast. It can simulate the voltage disturbance, frequency disturbance and three-phase imbalance of the grid; it is used in new energy industries such as storage Grid-connected performance testing of energy inverters, photovoltaic inverters, charging piles and other products。
◆ Adopt advanced direct digital frequency synthesizer (DDS) waveform generation technology, with high frequency stability and good continuity。
◆ Provide embedded intelligent PC monitoring system。
◆ The output frequency is 45.000-99.999Hz, with 0.001 Hz/10ms variable, can easily and accurately do under-frequency experiment, anti-islanding experiment; LIST, STEP two major modes, can perform 30 groups of different voltages and frequencies Setting of rate and time, and continuous loop test. The running time can be set to 10ms, which can be used to simulate the power grid test, realize the voltage and frequency gradient, step function, with active PFC, easy to complete It is a low voltage and zero voltage ride through test。
◆ You can do over/under voltage, over/under frequency experiments; set the required change voltage or frequency on the programmable panel. After running, every change in voltage or frequency will trigger a level. Do this experiment It is very accurate and convenient。
◆ High measurement accuracy, suitable for current sine half-wave and similar testing of various waveforms with DC component。
◆ Provide readings of root mean square voltage, root mean square current, active power, frequency, power factor, peak current, etc。
◆ For 100% load removal, the response time is within 2ms, the overload capability is strong, and the instantaneous current can withstand 3 times the rated current。
◆ External zero voltage crossing synchronous trigger signal dry contact, which is convenient for users to test。
◆ It has two parts of DC and AC output, among which the DC voltage is not adjustable, and it is fixed 300V (single-phase input) and 500V (three-phase input) (optional)。
