Adjustable Voltage 5-20kVA Programmable AC

Power Supply for AC Power Adapter Testing 

45-400Hz

Programmable AC Power Source for AC Power Adapter Testing

The 5-20kVA Programmable AC Power Supply is designed to provide adjustable AC input power for power adapter development, verification, and production testing. By adjusting the output voltage and frequency, it allows engineers to establish different AC input conditions when evaluating compatible power adapters and electronic power conversion products.

Available in four capacity options — 5kVA, 10kVA, 15kVA, and 20kVA — this single-phase input AC power source accommodates different testing power requirements. Its 7-inch color touchscreen, preset voltage and frequency settings, online parameter adjustment, voltage ramp function, and power-off memory help make routine testing operations more convenient.

Key Features

1. Adjustable AC Voltage for Power Adapter Input Testing

Provides adjustable AC output voltage for supplying power to compatible AC power adapters. Users can select the required voltage according to the adapter's rated input specifications, making it suitable for evaluating adapter operation under different input voltage conditions.

2. Variable Frequency Output from 45–400Hz

Supports adjustable output frequency within the specified operating range. This allows users to select different AC input frequencies when testing power adapters designed for different frequency requirements, including compatible products requiring 400Hz AC input.

3. Four Power Capacity Options: 5kVA to 20kVA

Available in 5kVA, 10kVA, 15kVA, and 20kVA configurations. Users can select a suitable capacity according to the power consumption and testing requirements of their power adapters or connected equipment.

4. 7-Inch Color Touchscreen for Clear Operation

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 AC power supply during testing.

5. Preset Parameters and Online Adjustment

Users can preset output voltage and frequency parameters and adjust them online during operation. The power-off memory function retains the previous output mode and parameter settings, which is useful for repeated power adapter testing procedures.

6. Voltage Ramp Function for Gradual Voltage Changes

The voltage ramp function gradually increases the output voltage toward the selected setting. It can be used when evaluating how a compatible power adapter responds to a gradual change in its AC input voltage.

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 power adapter 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.
