    Overview

    This 1 phase frequency converter provides reliable conversion from 230V 60Hz input to 120V 50Hz output, with 15kVA/20kVA capacity and adjustable frequency up to 400Hz for demanding industrial and testing applications. It delivers a pure sine wave output with low harmonic distortion (≤2%), ensuring stable operation for sensitive and precision equipment. The AC frequency converter supports resistive, capacitive, inductive, and non-linear loads, and features up to 3× instantaneous overload capability to handle high inrush currents. A clear 4-digit LED display shows voltage, current, power, and frequency simultaneously, while comprehensive protections---including over-current, over-temperature, short-circuit, and fault alarms---ensure safe and continuous operation.

    FAQ

    Q1: How is efficiency affected at partial load?

    Efficiency is highest at 60–80% load. At very light loads, internal losses account for a higher percentage of power, reducing overall efficiency slightly.

    Q2: Does the 1 phase converter require an external transformer?

    No. The converter integrates voltage and frequency conversion internally. An external transformer is not required unless site-specific isolation or special grounding is needed.

    Q3: Can the output be used to supply multiple devices simultaneously?

    Yes, provided the total apparent power (kVA) and combined inrush current do not exceed the rated capacity.

    Big money, but worth it if you need serious power conversion
    Running some 400Hz testing gear off this thing, and it hasn't missed a beat. Clean sine wave, rock-solid frequency, and the display shows everything at once. Overload handling is legit – handles startup surges without tripping. Heavy beast though; make sure you've got a spot for it. Five stars.
