Overview
The LSP-KVAS Series PWM Type AC Power Supply features ultra-low output voltage distortion and configurable output current protection, developed for testing home appliances, motors, compressors and similar industries — replacing traditional voltage regulators and frequency converters.
Two power tiers are available: LSP-3KVAS (3000W, 0-150V at 25A / 150-300V at 12.5A) and LSP-5KVAS (5000W, 0-150V at 42A / 150-300V at 21A), sharing the same IGBT SPWM circuit topology, protection features and measurement capability. More than 5kVA available by custom order.
Circuit form: IGBT SPWM pulse width modulation. Self-protection: over-voltage, over-current, over-load, short-circuit, over-temperature with automatic alarm display. Measures voltage, current, power and power factor.
