Variable Frequency AC Power Supplies
The VFP series AC Power Supplies are high precision, high efficiency, low THD adjustable AC power supplies that converts the input mains power through AC→DC→AC conversion, and gives a pure sine wave AC output with adjustable voltage & frequency within a certain range. Also known as Variable Frequency AC Power Source.
According to the difference in the number of output phases, it can be divided into single-phase and three-phase AC power supplies.
The output power of single-phase adjustable AC power supply ranges from 500VA to 200KVA, the output power of three-phase adjustable AC power supply ranges from 3KVA to 600KVA, the output voltage is divided into 0 ~ 150Vac, 150 ~ 300Vac, and the output frequency is adjustable from 45Hz to 70Hz with 50/60Hz fixed frequency output.
Through the friendly operation panel, you can read the output data such as output voltage, output current, output power, power factor, etc., providing accurate data records for your test, and can add RS485 interfaces as standard, following the MODBUS-RTU international communication protocol, which can realize remote control and operating status monitoring of the power supplies.
This series of adjustable AC Power Supplies have comprehensive protection functions, such as: over voltage, over current, over temperature and short circuit protections, which can protect the AC power supplies and DUT from damages. At present, it is mainly used for Various electrical appliance manufacturers conduct grid simulation tests on electrical appliances according to the voltage/frequency requirements of different countries. Imported electrical appliances are used for the domestic demand for variable voltage and frequency conversion, as well as various AC motors and AC transformers.
