Programmable AC Constant Current Source 5V 300A SPWM constant current tester
Product overview:
CCS2000 series programmable AC constant current source adopts SPWM high frequency pulse width modulation to provide pure and stable sine wave with small harmonic components, no interference and high precision. It can modulate the output current and frequency, with fast response speed, high constant current precision and long-term stable operation. It can also overcome the current changes caused by grid voltage fluctuations, loop resistance changes and product internal resistance changes, and is not affected by human factors. It has small size, high efficiency, reliability and maintenance cost compared with traditional voltage regulators. It provides embedded intelligent PC monitoring system, which can be used with advanced production line systems or used alone. It is mainly used for current thermal effect testing and application of specific products, such as protective switches such as circuit breakers, fuses, thermal relays, magnetic starters and various transformers, which need to set rated current, operating current, short-circuit current and other thermal effects for testing. Low-voltage electrical appliance manufacturing enterprises, electrical appliance testing institutions, electrical appliance research units, and university training bases. Molded case circuit breaker delay characteristic test and verification equipment, molded case circuit breaker instantaneous characteristic test and verification equipment, small circuit breaker instantaneous characteristic test and verification equipment, lean production testing line.
