Product Summary

Shenzhen Tuoweide Technology Co., Ltd. offers customizable AC constant current sources in various specifications.

The TCV8000 series AC constant current source utilizes SPWM high-frequency pulse width modulation, with IGBT achieving the output. It can modulate the output current and frequency, offering fast response and high constant current accuracy, ensuring long-term stable operation. Additionally, it can overcome current changes caused by fluctuations in grid voltage, changes in circuit resistance, and product internal resistance, unaffected by human factors. It is compact, high-efficient, and has a significant advantage in reliability and maintenance costs compared to traditional voltage regulators. It is mainly used in specific product current thermal effect testing and applications, such as circuit breakers, fuses, thermal relays, magnetic starters, and other protective switches, as well as various transformers that require setting and testing of rated current, operating current, and short-circuit current thermal effects. It is also used by low-voltage electrical appliance manufacturing enterprises, electrical testing institutions, electrical research units, and university training bases. It includes test and verification equipment for time-delay characteristics of molded-case circuit breakers, instantaneous characteristics of molded-case circuit breakers, and instantaneous characteristics of small circuit breakers, as well as lean production inspection lines.
