The 60Hz Variable Frequency Power Supply Series converts AC power through a power conversion circuit to the required voltage and frequency. Its main features include pure and reliable sine wave power output, low harmonic distortion, and high stability in frequency and voltage regulation. It can simulate output characteristics of different voltages and frequencies worldwide, covering the entire industry's needs and fully complying with applications such as engineers' design and development, production line testing, quality assurance product inspections, lifespan testing, over-voltage/under-voltage simulation tests, power supply for imported equipment, and production lines. Additionally, this power system supports 400Hz for aerospace applications.

High reliability

All major components are imported, featuring original Mitsubishi IGBT inverter modules, driven and protected by the original Japanese Mitsubishi core, with a comprehensive drive protection circuit ensuring reliable IGBT operation.

2. Fast dynamic response time ()

Utilizing a dual closed-loop feedback circuit, the inner current loop ensures non-linear load waveforms are not distorted; the outer voltage loop guarantees a sudden load voltage drop of less than 1%, with a response time less than 2mS. The control circuit is an analog circuit, featuring strong anti-interference capabilities and no system crashes. Some manufacturers use digital control sampling that requires A/D conversion, calculation, and D/A conversion, resulting in a longer control process, slower response time, weaker anti-interference capabilities, and a higher likelihood of system crashes.

3. Three-phase power can accommodate any unbalanced load

Three-phase power supply can be either synchronized in three phases or individually adjusted in single phases. The main circuit and control circuit of the three-phase power supply are designed based on three independent single-phase power supplies. The main circuit employs a rectifier, DC filter, inverter, AC filter, and transformer, among other components, in a three-stage AC-DC-AC configuration. The three single-phase inverter circuits output at a 120-degree phase difference, ensuring electrical independence on the primary side of the transformer. On the secondary side, they are connected in a star configuration to produce the required three-phase AC power. Voltage and waveform control for single-phase outputs are handled by three independent single-phase controllers, allowing any phase of the three-phase power supply to be used as a standalone single-phase power source. This capability adapts to any unbalanced load, significantly enhancing the power supply's load adaptability. It truly achieves load balance regardless of the unbalance.

4. User-friendly interface; integrated sensor and display; high measurement accuracy

Voltage, frequency, current, power/power factor four-window measurement display, accuracy of 0.5 class, source meter integrated.

5. High loading capacity

Power components are applied reasonably, capable of withstanding 3 times the rated current without causing voltage drop.

6. Enhanced Stability

Frequency stability ≤ 0.01%, load stability ≤ 1%, the output frequency is generated by a quartz oscillator, thus it is highly stable and accurate.
