UNI-T UAP500A Programmable AC Power Source 500VA

Features:

• Programmable AC Output: Generates adjustable AC voltage and frequency for controlled testing of electrical and electronic equipment.

• 500VA Output Capacity: Provides a 500VA apparent-power rating for laboratory testing, product development, and quality inspection.

• Wide Voltage Adjustment: Supports selectable low- and high-voltage ranges, with output adjustable from 0–150VAC or 0–300VAC.

• Adjustable Frequency: Offers an output frequency range of 45–250Hz for testing equipment under different AC supply conditions.

• Low-Distortion Waveform: Uses sinusoidal pulse-width modulation (SPWM) to generate a low-distortion AC waveform.

• Four-Window Display: Displays key measurement parameters simultaneously, including RMS voltage, RMS current, frequency, power, and power factor.

• Preset Memory: Stores up to nine groups of settings for faster setup during repeated tests.

• Remote Control: Supports computer-based operation through the RS-232C interface, with SCPI and Modbus protocol support.

• Output Delay Function: Allows the output voltage to rise gradually toward the set value, helping protect equipment sensitive to sudden voltage changes.

• Dual Output Connections: Provides front- and rear-panel output connections for flexible bench or rack installation.

• Built-In Protection: Includes overcurrent, overtemperature, overload, and short-circuit protection.
