Variable Voltage Variable Frequency Source (Single Phase)

Variable Voltage Variable Frequency Source (Single Phase)

We are Manufacturer, Supplier, Exporter of Variable Voltage / Variable Frequency Source (Single Phase) also widely known as frequency converter. It is designed for the applications where controlled variation in voltage & frequency are required. While designing this source we have ensured that it provides smooth voltage adjustment from desired lower voltage range to higher voltage rated output ideal for simulating under-voltage & over-voltage conditions. Our source delivers clean sinusoidal waveform with minimum harmonic distortion.

Features

Pure Sine wave with variable frequency.
Overload and short circuit protec.
Setting by Decade switches for V/A in 5½ digit.
Frequency setting by potentiometer.
Separate output ports for V(Hi), mA(Hi), 10A(Hi) & Com.
Parameter and range selection by inbuilt micro controller based unit and relays. Bar of LEDs to indicate parameter and range.

It can be used for

Testing of Domestic & Industrial Appliances across different voltage and frequency conditions.
R&D Simulations: Real-world voltage/frequency Simulations.
Testing of consumer electronic products like washing machine, fan, microwave oven, etc & medical equipments.
Demonstration of power electronics & electrical units in Educational Labs.
