Household Appliance Testing with 15kVA 10kVA 5-

20kVA Variable AC Power Supply 0-300V 45-400Hz

Variable AC Power Supply for Household Appliance Testing

The 5-20kVA Variable AC Power Supply is designed to provide adjustable AC power for household appliance development, functional evaluation, and production testing. With adjustable output voltage and frequency, it allows users to supply compatible appliances under selected AC input conditions during engineering evaluation and testing procedures.

Available in four capacity options — 5kVA, 10kVA, 15kVA, and 20kVA — this single-phase input AC power supply provides different power capacity choices for household appliance manufacturers, laboratories, and electronic product testing environments.

The system features a 7-inch color touchscreen, preset voltage and frequency settings, online parameter adjustment, power-off memory, and a voltage ramp function to support convenient operation during repeated testing procedures.

Key Features

1. Adjustable 0–300V AC Output

Provides adjustable AC output voltage for supplying household appliances with different rated input voltage requirements. Users can select the required voltage according to the specifications of the appliance under evaluation.

2. Variable Frequency Output from 45–400Hz

Supports adjustable output frequency within the specified operating range. Users can select different AC input frequencies when evaluating compatible household appliances designed for different power frequency conditions.

3. Four Power Capacity Options

Available in 5kVA, 10kVA, 15kVA, and 20kVA configurations. These capacity options allow users to select a suitable AC power source according to the power requirements of different household appliances and testing setups.

4. 7-Inch Color Touchscreen

The 7-inch color touchscreen provides an operating interface for setting output parameters and viewing operating information. It displays voltage, current, power, frequency, and power factor, helping users monitor the power supply during appliance testing.

5. Preset Voltage and Frequency Settings

Users can preset output voltage and frequency parameters for repeated testing procedures. The online adjustment function allows voltage and frequency settings to be changed during operation, while the power-off memory function retains the previous output mode and parameter settings.

6. Voltage Ramp Function

The voltage ramp function gradually increases the output voltage toward the selected setting. This provides an adjustable voltage transition when evaluating how compatible household appliances respond to a gradual change in their AC input supply.

7. Multiple Protection Functions

The power supply provides overload, overcurrent, overvoltage, overheating, and short-circuit protection. When a protection condition occurs, an alarm and corresponding fault code are displayed to help users identify the event.

8. Aging Impact Mode

The aging impact mode provides an operating option for applications involving power-on and power-off impact conditions. It can be incorporated into a household appliance aging evaluation setup according to the user's testing procedure.

9. SPWM Control and IGBT Power Drive

The system uses high-frequency SPWM hardware adjustment and a high-power IGBT drive design as part of its power conversion and output control system.
