TCV8000 Series AC Constant-Current Power Supplies - Shenzhen Tuowode Manufacturer - AC Constant-Current Power Supplies, Constant Voltage Constant-Current Power Supplies Factory
Product Overview
Shenzhen Tuowode Technology Co., Ltd. offers customizable AC constant current sources in various specifications.
The TCV8000 series AC constant current sources use SPWM high-frequency pulse width modulation and IGBT for output, enabling adjustment of output current and frequency. They feature fast response, high constant current accuracy, and long-term stability. Moreover, they can overcome current fluctuations caused by voltage fluctuations in the power grid, changes in loop resistance, and product internal resistance, and are unaffected by human factors. They are compact, efficient, and have significantly lower reliability and maintenance costs compared to traditional voltage regulators. They are mainly used in specific products for 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, short-circuit current, and other thermal effects. They are also used by low-voltage electrical appliance manufacturing enterprises, electrical testing institutions, electrical research units, and university training bases. Additionally, they are used for testing and verification equipment of delay characteristics for molded-case circuit breakers, instantaneous characteristic testing and verification equipment for molded-case circuit breakers, small circuit breaker instantaneous characteristic testing and verification equipment, and lean production inspection lines.
