2. Output Range:
    a. Voltage - Low level: 0~150V, High level: 150~300V or 0~300V continuously adjustable (best simulate input voltage of different countries)
    b. Frequency: 45~70Hz (adjustable)
            50Hz, 60Hz, 100Hz, 200Hz, 400Hz (fixed)
    c. Power: 500VA ~ 200KVA for selection.
3. High output voltage accuracy and output frequency stability
4. Response time: 2ms
5. 0.5% load stability.
6.  ±1.5% waveform distortion (resistive load)
7. High-accuracy display for output voltage, current, frequency, power & power factor.
8. Full Protection functions (over voltage, over load, over temp, over current, short-circuit)
9. Friendly Operation Panel


Applications

1. For electron-products testing, debugging, powering for electro-instrument
2. Electromotor, electron manufacturing, IT industry, computer, labs and so on.
3. Other situations that need frequency conversion power supply

Storage

Pay attention to the following points during temporary & long-term storage.
1. Store the power supply in our packing box
2. Long-term storage would lead to electrolytic capacitor degradation, it should be powered up yearly, at least 5 hours power-on time, input voltage should be increased to rated value by voltage regulator.
