An AC power supply, also known as AC power source, provides variable power and variable frequency to AC-powered devices. Having adjustable output voltage, frequency and waveform, an AC power supplies can simulate different kinds of electrical grids, as well as grid interruption, surges, fault conditions. They are widely used in laboratory testing, R&D and industrial production.

By phase configuration, AC power supplies can be divided into two categories: single phase AC power supply and three phase AC power supply.

• A single phase AC power supply uses two-wire connection: one phase wire and one neutral wire (L+N). Single-phase power is normally used for small devices, most typically home appliances and office appliances.
• A three phase AC power supply uses three-wire connection: three phase wires (L1+L2+L2). Three-phase power is normally used for high-power equipment and machineries, for example heavy motors, compressors.

In the range of single phase output, TWINTEX provides two product series:

TFC61 series, capacity 5kVA to 800kVA, frequency 45Hz to 400Hz

TFC400-61 series, capacity 500VA to 800kVA, frequency 320Hz to 480Hz

In the range of three phase output, TWINTEX also provides two product series:

TFC63 series, capacity 3kVA to 800kVA, frequency 45Hz to 65Hz

TFC400-63 series, capacity 1.5kVA to 800kVA, frequency 320Hz to 480Hz

Customization on voltage range and frequency range can be adapted case by case.
