Grid Interference in HVAC Testing? Meet Preen Power at AHR Expo 2026
2026/08/12
In HVAC and refrigeration R&D, data integrity is the cornerstone of all quality efforts. However, an often-overlooked hidden cost lurks within the power grid: unstable power quality directly causes distorted test data, leading to expensive retesting and severely delaying time-to-market.
As a seasoned power electronics manufacturer, Preen understands the critical need for precise, pure power supplies for industry clients. Visit us at AHR Expo Mexico 2026—Latin America's premier HVACR event—held from September 29 to October 1, 2026, in Guadalajara, Mexico.
We will spotlight two flagship products designed to enhance testing accuracy and reliability: the AFV-P Series Programmable AC Power Supply and the ADG-L Series Programmable DC Power Supply. Delivering pure waveforms and isolating grid interference, they ensure your test results accurately reflect product performance and help you pass verification on the first attempt.
∎ AFV-P Series Programmable AC Power Supply
Engineered for rigorous industrial and HVAC system testing, delivering standard-source-grade pure power.
- Maximum output voltage up to 310 V; upgraded version reaches 350 V, maximum frequency up to 2000 Hz
- Harmonic distortion as low as ≤ 0.3% with low interference, ideal as a standard source for testing and verification
- Supports single or continuous test procedures such as voltage and frequency soft rise, soft fall and step change, facilitating verification of equipment power input reliability
- 4.5/9 times peak current, suitable for devices under test with inrush current
- Compliant with EMC limit requirements of IEC61000-3-2 / GB 17625.1
∎ ADG-L Programmable DC Power Supply
Efficient and stable, providing a broad DC test solution for industrial power and control applications.
- Output voltage range: 0-30V, 0-1000V, maximum up to 2000V
- Series/parallel operation function greatly boosts output power and voltage
- Features three output modes: CC/CV/CP
- High power density and lightweight body design
- Supports I-V curve simulation and remote control software
