Linear Frequency Conversion Variable AC Power Source Supply TPAL Series

TPAL Series Linear Frequency Conversion Power Programmable AC Power Supply

The TPAL series power supplies utilize IGBT/SPWM technology, offering simple operation and pure sine wave output. The output power ranges from 500VA to 2000kVA. Under resistive load conditions, the distortion is as low as 1%. There are two output voltage ranges available: 0-150V and 0-300V (with an optional 0-600V). The output frequency can be quickly selected between 50Hz and 60Hz. The standard output frequency range is 45-65Hz, with an optional continuous adjustment range of 45-400Hz. A standard RS232 communication interface is included for remote control, enabling simulation of different voltage and frequency output characteristics from around the world to meet various industrial needs.

Product Features:

• Single-phase output from 500VA to 100kVA, three-phase output from 10kVA to 2000kVA;

• Four-digit LED display for measuring voltage, current, frequency, power, or power factor;

• Automatic high/low voltage selection: auto-switch between 0-150V and 150.1-300V, or lock at the high range of 1-300V;

• Comprehensive protection including overcurrent, overload, overtemperature, and undervoltage input protection, with corresponding error codes;

• High surge resistance, capable of directly starting inductive loads up to 1/3 of the power supply capacity;

• Capable of independent three-phase loading and setting individual start for R, S, and T phases;

• Adjustable voltage and frequency while in output mode;

• Lock key function, quick key input, knob operation;

• Standard RS232 communication interface, optional RS485/GPIB communication interface or analog control mode;

• Power-down memory function, automatically remembers the last output parameters."
