TCC-series AC Constant Current Power Supply
| TCC-series is AC constant current source is primarily designed for low-voltage electrical appliance manufacturers, inductive component manufacturers, electrical testing organizations, electrical research institutes, and university training bases. It is suitable for testing and calibrating the time-delay and transient characteristics of components like circuit breakers and relays. It is also suitable for testing the rated current, operating current, short-circuit current, and other thermal effects of inductive components like transformers, instrument transformers, and inductors. The product utilizes SPWM high-frequency inverter control technology and IGBT output conversion, resulting in high accuracy, fast response, low distortion, and excellent current stability. Active PFC technology is employed at the input, resulting in a high input power factor and minimal grid pollution. This makes it a highly efficient and energy-efficient current measurement device. |
Features
Using an advanced current closed-loop control strategy, it achieves stable current output, unaffected by load fluctuations. Compared to the traditional voltage source + load + device under test test method, this significantly reduces capacity and energy consumption, eliminates large-capacity loads, and significantly reduces costs.
Using SPWM high-frequency inverter technology to achieve constant current output, it offers higher precision, faster response, lower distortion, and higher efficiency than motor-controlled constant current sources. Temperature drift caused by external temperature changes is negligible, making it a future trend in industry testing.
