VFP-S Single-phase Variable Frequency AC Power Supply
Vfp-S Single-Phase Variable Frequency AC Power Supply

Brief Introduction

The VFP-S series is single-phase output model which has various output range from 500VA to 200KVA, it has high resolution & stability and full protection functions, output voltage & frequency continuously adjustable and easy operation-panel. It's widely used as a simulated AC input for equipment or home appliance testing.


1. Output voltage & frequency adjustable via potentiometer or key button
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


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

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.  


1. The warranty period of this product is 12 months, free repair within warranty period except for man‐made damages or irresistible forces.
The following cases during under warranty are not included in free-warranty scope:
(1). Incorrect operation & maintenance of the power source that cause fault.
(2). Natural loss of consumable material (shell, connector etc.)
(3). Manual damage caused by modification or dismantle
(4). Damage caused by external equipments or third-party product or plug-in units.
(5). Force majeure factors, such as fire, flood or input grid abnormal.
(6). Unilateral amendment or modification on our LOGO or part number.
(7). Fault caused by abnormal usage of power source.
(8). Other non-product quality causes
2. Reasonable maintenance & repair costs should be charged after warranty period.
