Programmable AC Power Source for UPS System Testing

The 5-20kVA Programmable AC Variable Frequency Power Supply is designed to provide adjustable AC input power for UPS system development, verification, and testing. With adjustable output voltage and frequency, it allows engineers to establish different AC supply conditions when evaluating compatible uninterruptible power supply (UPS) systems and related power equipment.

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, power-off memory, and voltage ramp function support convenient operation in laboratory and production testing environments.

Key Features

1. Adjustable AC Output Voltage for UPS Input Testing

Provides adjustable AC output voltage for supplying power to compatible UPS systems during input testing. Users can select the required voltage according to the rated input specifications of the UPS under evaluation.

2. Variable Frequency Output from 45–400Hz

Supports adjustable output frequency within the specified operating range. This allows engineers to establish different AC input frequency conditions when evaluating compatible UPS systems designed for different power frequency requirements.

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 requirements of the UPS system and the intended testing setup.

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 AC power source during testing.

5. Preset Voltage and Frequency Settings

Users can preset output voltage and frequency parameters for repeated testing procedures. Online adjustment 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. It can be used when evaluating how a compatible UPS system 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 UPS system evaluation or aging test 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.
