Communication inverter variable frequency power supply
AHY-12 STANDARD SERIES AC CONSTANT CURRENT SOURCE
The AHY-12 standard series AC constant current source uses SPWM high-frequency pulse width modulation, which can modulate the output current and frequency. It features fast response speed, high constant current accuracy, and long-term stable operation. It can overcome current changes caused by fluctuations in grid voltage, changes in loop resistance, and changes in product internal resistance, and is unaffected by human factors. It is mainly used for current thermal effect testing and applications of specific products, such as circuit breakers, fuses, thermal relays, magnetic starters, and other protective switches, as well as various transformers that require testing of rated current, operating current, and short-circuit current thermal effects. Target users include low-voltage electrical appliance manufacturers, electrical testing institutions, electrical research units, and university training bases. Applications include: molded case circuit breaker characteristic testing and verification equipment, miniature circuit breaker instantaneous characteristic testing and verification equipment, and lean production testing lines.

The AHY-15 standard series AC constant current source is a wide-spectrum, high-precision, low-harmonic, low-distortion constant current source. This constant current source is an AC power supply that can maintain a constant output current even when the external power grid fluctuates or the impedance characteristics of the load change. This power supply is mainly used in products and places where specific current thermal effects are applied and tested. For example, experiments on circuit breakers, fuses, thermal relays, magnetic starters, coils, etc.
