Regenerative AC Source & Load ANRGL(F)

The ANRGL(F) Series Regenerative AC Source/Load Unit adopts advanced digital control methods and power conversion technology, with selectable AC/DC output modes, providing precise power input for AC loads, DC loads, and rectifier-type loads, etc. The product features four-quadrant operation capability, which can significantly save energy consumption and reduce operating costs. It can set waveform switch-on and switch-off angles for testing surge current and output maintenance time. It can also set the rate of change of voltage and frequency to sweep the range of power input specifications for the DUT. The power supply mode can simulate abnormal instantaneous rise, drop, short circuit, jitter, and other phenomena in the power grid, simulate distortion of the mains power waveform, and also provide accurate and fast measurement of power parameters. The load mode features a full four-quadrant feedback AC electronic load, capable of absorbing full- capacity energy and providing high-efficiency grid feedback to reduce power consumption; multiple load modes are available to meet different test conditions. The ANRGL(F) Series Regenerative AC Source/Load Unit Integrated Machine adopts advanced SPWM technology with excellent power output quality, widely used in laboratories and production lines in the photovoltaic, new energy vehicle, and other industries.

AC, DC, and AC+DC output mode

Start-stop Angle

In the conventional mode, the start-stop angles of the waveform can be set to facilitate surge current tests.

Output Waveform Options

The three-phase output waveform can be independently set to select a sine wave, a square wave, a triangular wave, a clipped sine wave, 30 sets of built-in waveforms, and 6 sets of user-defined waveforms.

Sequence Mode

It has universally programmable settings for each phase of AC voltage, DC voltage, and frequency. Phase, waveform, and time can be independently set according to single-step settings. Trigger phase and loop count can be set, and parameters of three-phase outputs can be separately configured. Any phase abrupt change/crossing test can be achieved. Rich sequence combinations with a high degree of freedom in parameter settings. By setting different combined sequence parameters, high- and low-voltage crossing tests can be completed. Minimum programming setting time is 1ms, capable of completing a 1ms stop test. Each sequence in each phase can independently set one of the 6 waveforms.

Pulse Mode

It periodically changes the output state, where the power output will cyclically vary between a regular power supply and a pulse voltage. Each phase of AC voltage, DC voltage, frequency, angle, waveform, time, etc., can be independently set.
