AF50W-310005 5kVA AC Power Supply for Unstable Grid & Generator Power

Your Equipment Is Stable. Is Your Power Supply?

Electrical equipment is often designed for a specific voltage and frequency. The actual power available at the installation site, however, may not remain within those conditions.

Voltage can rise or fall. Generator frequency can fluctuate. Different countries may also use different power standards.

The ACSOON AF50W-310005 5kVA AC Power Supply is designed to create a more stable electrical environment between the incoming power source and the connected equipment.

Unstable Input → Voltage & Frequency Conversion → Stable AC Output

Protection & Reliability

The AF50W series provides protection against:

Over/Under Voltage | Overcurrent | Overload | Overtemperature | Short Circuit

Operating conditions specified for the series include -10°C to +50°C, 10–95% humidity and noise below 65dB at one metre. MTBF is specified at 50,000 hours.

When Should You Consider AF50W?

AF50W may be suitable when:

Your grid voltage frequently fluctuates

Your equipment is powered by a generator

Your equipment requires stable 50Hz or 60Hz

Imported equipment uses different power requirements

Your laboratory needs a regulated AC source

Production equipment is sensitive to power quality

You need voltage and frequency regulation in one system

Key Advantages

Wide Input Tolerance

The AF50W series is designed to handle input voltage fluctuations of approximately ±30%, depending on the selected configuration.

Voltage + Frequency Regulation

Provides ±1% voltage regulation and ±0.1% frequency regulation, with 50Hz or 60Hz output available.

Galvanically Isolated Output

The isolated output transformer separates the load side from the incoming power source and supports professional electrical applications.

Pure Sine-Wave Output

Clean sine-wave output with THD <3% for linear loads.

SPWM + IGBT Technology

Rectifier/inverter conversion with SPWM and IGBT technology provides electronic regulation rather than relying only on traditional mechanical voltage correction.

Real-Time Display

The front panel displays:

Voltage | Current | Frequency | Power / Power Factor

04

Quality Control

Cold chamber test – Every unit runs at -30°C for 2 hours. Heater must hold internal temp above 0°C.

Hot chamber test – 55°C for 4 hours at full load. No over‑temp alarms.

IP56 water test – High‑pressure spray from all directions for 10 minutes. No water inside.

Sand test – Blown sand against the intake for 30 minutes. Filter catches it.

05

R&D Results

Heater placement – First unit had heater near the top. Heat rose, bottom stayed cold. Moved to the bottom. Much better.

Filter design – Original filter clogged fast in heavy dust. Switched to a cyclonic pre‑filter. Lasts 10x longer.

Door seals – Used automotive‑grade bulb seals. Stays flexible down to -40°C. No cracking.

Customer feedback – An Arctic operator wanted a way to check internal temp without opening the door. Added a display on the outside.
