High-precision variable frequency power supply with 0-520V output and 400Hz adjustable frequency capability
Product Overview
The IGBT/PWM variable frequency power supply is a high-precision, high-efficiency power conversion device that utilizes IGBT (Insulated Gate Bipolar Transistor) technology and advanced PWM (Pulse Width Modulation) control. This system converts standard industrial frequency mains power into pure sine wave AC power with continuously adjustable voltage and frequency across a wide range.
Key Features
4-digit real-time display of voltage (V), frequency (Hz), current (A), power (W), and power factor (PF)
No radiation interference with minimal harmonic components, delivering pure and stable sine wave output
Compatible with resistive, capacitive, inductive, and non-linear loads
Strong overload capacity capable of withstanding 300% of rated current instantly
Comprehensive protection systems including overcurrent, over-temperature, short circuit, and instant power-off protection with warning devices
