Sinuo - Model SNP-CCS1000 - AC Constant Current Source for High Frequency Pulse Output

SHARE
The AC constant current source utilizes SPWM (Sine Pulse Width Modulation) high-frequency pulse width modulation. With IGBT technology, it can accurately modulate both the output current and frequency. This product is characterized by its rapid response speed, high accuracy in maintaining constant current, and long-term stable operation. It effectively mitigates current variations due to grid voltage fluctuations, loop resistance changes, or internal resistance changes, remaining unaffected by human factors. It is compact, efficient, and offers a higher reliability and lower maintenance cost compared to traditional voltage regulators. This equipment is primarily used for testing and application of thermal effects caused by current in various products, including circuit breakers, fuses, thermal relays, magnetic starters, and transformers. The device's technical specifications include single-phase 127V ±10% input voltage, adjustable frequency within 47-63 Hz, and an adjustable current output range from 0 to 100A. It features an LED display for voltage, current, frequency, and power wattage, along with several protection modes for over current, temperature, load, and short circuits.
