3kVA/10kVA Three Phase Frequency Converter, 208V 60Hz to 420V 50Hz

The 3 phase frequency converter provides adjustable three-phase voltage and frequency with stable pure sine wave output for reliable operation. It supports multiple input configurations and features real-time monitoring of voltage, current, power, and frequency via integrated digital displays. Widely used in laboratories, production lines, automotive and electronic testing, and 400Hz aerospace power systems, the AC frequency converter handles high inrush loads and includes comprehensive protection for safe operation.

Feature

• Static frequency converter supports 380VAC three-phase input with 50Hz/60Hz frequency and 0-520VAC three-phase output adjustable from 40-400Hz.
• Measures and displays voltage, frequency, current, and power simultaneously, with no switching required.
• Delivers clean, stable pure sine wave output, suitable for precision and sensitive equipment testing.
• Simulates global standard voltages and frequencies for testing a wide range of electrical products.
• Handles high inrush loads, with instantaneous current capacity up to 3× rated current.
• Equipped with over-current, over-temperature, short-circuit, and power-failure protection with alarm.
• Compatible with resistive, capacitive, inductive, and non-linear loads.
