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."
