TCV8000 Series AC Constant Current Source - Shenzhen Tuowode Manufacturer's AC Constant Current Source - TCV8000 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, with IGBTs for output. They can modulate output current and frequency, featuring 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 variations in product internal resistance, remaining unaffected by human factors. They are compact, efficient, and have a significant advantage in reliability and maintenance costs compared to traditional voltage regulators. Primarily used for specific product current thermal effect tests and applications, such as circuit breakers, fuses, thermal relays, magnetic starters, and other protective switches, as well as various transformers requiring tests of rated current, operating current, short-circuit current, and other thermal effects. Also used by low-voltage electrical appliance manufacturing enterprises, electrical testing institutions, electrical research units, and university training bases. Additionally, for testing and verification equipment of delayed characteristics for molded-case circuit breakers, instantaneous characteristics for molded-case circuit breakers, small circuit breakers, and lean production inspection lines.
Product Features
◇ Constant current, current adjustment range: Continuous adjustment from 0 to rated value.
