SPWM High Frequency Pulse AC Constant Current Source Width Pulse Width Modulation

SPWM High Frequency Pulse AC Constant Current Source Width Pulse Width Modulation

Product Information For AC Constant Current Source:

The AC constant current source adopts SPWM high frequency pulse width pulse width modulation, IGBT realizes the output, can modulate the output current and frequency, has a fast response speed, high constant current accuracy, and long-term stable operation. And it can overcome current changes caused by grid voltage fluctuations, loop resistance changes, and product internal resistance changes, without being affected by human factors; small size, high efficiency, reliability and maintenance costs have obvious advantages over traditional voltage regulators; mainly used for testing and application of current thermal effects of specific products, such as circuit breakers, fuses, thermal relays, magnetic starters and other protective switches and various types of transformers where thermal effects testing applied such as rated current, operating current, short-circuit current, etc.

Feature For AC Constant Current Source:

1. Constant current, constant current adjustment range: 0-max. value continuous adjustment.

2. Constant pressure, constant pressure adjustment range: 0- max. value continuous adjustment.

3. Frequency conversion, frequency adjustment range: 47Hz-63Hz adjustable, fixed gears 50Hz, 60Hz, 100Hz, 120Hz.

4. When using constant current and constant voltage, it can be automatically cross-converted to maintain both control and protection characteristics.

5. Provide measurement of root mean square voltage, root mean square current, active power, frequency, etc.

6. Protection mode: over voltage, over current, overload, short circuit, current limit, etc.

7. Input and output are isolated.
