PWM Type AC Power Supply

The LSP-5KVAS PWM Type AC Power Supply features ultra-low output voltage total harmonic distortion (THD) and configurable output current protection thresholds. Engineered for compliance testing in accordance with IEC 61000-4-11 for voltage dips, short interruptions, and voltage variations immunity, this unit is specifically developed for testing applications in the home appliance, electric motor, and compressor industries. It serves as a high-performance replacement for conventional voltage regulators and frequency converters, delivering efficient, cost-effective, and precise testing solutions. The unit is equipped with four-wheel mobility for convenient relocation between laboratory environments.
