YIMAI POWER Programmable AC Power Source | Variable Frequency & Voltage Adjustable Pure Sine Wave Power Supply for Laboratory, Industrial Testing & Certification

Product Overview

The YIMAI POWER Programmable AC Power Source is a high-precision, industrial-grade AC power supply engineered to deliver stable, clean, and fully adjustable AC power for a wide range of testing and validation scenarios. Built on advanced pulse width modulation (PWM) technology, this power supply provides pure sine wave output with ultra-low harmonic distortion, allowing engineers and technicians to simulate ideal, abnormal, and extreme power grid conditions. Available in single-phase and three-phase configurations, with customizable voltage, frequency, and power ratings, it is the ideal solution for product R&D, quality control, reliability testing, and global certification compliance.

Core Technical Advantages

Precision Adjustable Output

The power source offers a wide adjustable voltage range (0~300V AC for single-phase, 0~520V AC for three-phase) and frequency range (40~400Hz), with high resolution (0.1V for voltage, 0.1Hz for frequency) and exceptional regulation accuracy (±0.1% for voltage, ±0.01% for frequency). This level of precision ensures accurate and repeatable test results, even for the most sensitive electronic devices.
Pure Sine Wave Output with Low Distortion

It delivers a pure sine wave output with total harmonic distortion (THD) of less than 2% at full load, matching the quality of ideal utility grid power. This clean power protects sensitive test samples from damage and ensures reliable performance during testing, making it suitable for high-precision electronics, medical devices, and aerospace equipment.
Intuitive Programmable Operation

The front panel features a large, high-resolution LCD display that provides real-time monitoring of output voltage, current, frequency, active power, and apparent power. Users can easily set parameters via the keypad and rotary knob, and program custom test sequences (e.g., voltage ramps, step changes, frequency sweeps, and duration cycles) to simulate power outages, surges, and grid fluctuations.
High Stability & Dynamic Response

Equipped with constant voltage/constant frequency (CV/CF) control logic, the power source maintains stable output even under dynamic load changes (0~100% load step), ensuring consistent performance during continuous testing. The advanced cooling system and robust component selection also guarantee long-term reliability and extended service life.
Comprehensive Protection & Safety

The system includes built-in over-voltage protection (OVP), over-current protection (OCP), over-temperature protection (OTP), and short-circuit protection, preventing damage to both the power supply and the device under test (DUT). The enclosure is made of heavy-duty metal with warning labels and a safety lock, ensuring safe operation in industrial and laboratory environments.
Flexible Communication & Mobility

Optional communication interfaces (RS232/RS485/USB) allow for remote control and data logging, enabling integration with automated test systems. The unit is mounted on heavy-duty casters for easy mobility between test stations, and the compact design saves valuable laboratory floor space.
