Shenzhen Tuoweide Manufacturer Discusses AC Constant Current Source - TCV8000 AC Constant Current Source Constant Voltage Constant Current Source Factory
TCV8000 Series AC Constant Current Source - Shenzhen Tuowode Manufacturer's AC Constant Current Source - TCV8000 AC Constant Current Source, Constant Voltage Constant Current Source Factory
Product Overview
Shenzhen Tuowode Technology Co., Ltd. offers customizable AC constant current sources in various specifications.
The TCV8000 series AC constant current sources utilize SPWM high-frequency pulse width modulation and IGBT for output, allowing for adjustment of output current and frequency. They feature fast response times, high constant current accuracy, and long-term stability. Moreover, they can overcome current fluctuations caused by voltage fluctuations in the power grid, changes in circuit resistance, and variations in product internal resistance, remaining unaffected by human factors. They are compact, highly efficient, and offer significant advantages in reliability and maintenance costs compared to traditional voltage regulators. Primarily 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. 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 calibration equipment of delay characteristics for molded-case circuit breakers, instantaneous characteristics for molded-case circuit breakers, and for small circuit breakers, as well as for lean production inspection lines.
