400Hz Avionics Equipment Testing 5-20kVA

Programmable AC Power Source 0-300V

Programmable AC Power Source for 400Hz Avionics Equipment Testing

The CP70 Series Programmable AC Power Source is designed to provide adjustable single-phase AC power for avionics equipment testing and other applications requiring variable voltage and frequency conditions. With a standard output voltage range of 0–300V and an adjustable frequency range of 45–400Hz, it can supply 400Hz AC power to compatible avionics equipment for laboratory evaluation, power supply verification, and functional testing.

Available in four capacity options — 5kVA, 10kVA, 15kVA, and 20kVA — the series accommodates different equipment power requirements. It features a 7-inch color touchscreen, online voltage and frequency adjustment, preset parameter settings, power-off memory, a voltage ramp function, and multiple protection functions.

Key Features

1. Adjustable 0–300V AC Output

Provides a standard single-phase output voltage range of 0–300V AC. Users can adjust the output voltage according to the rated input requirements of the connected equipment. A customized 0–600V output configuration is also available upon request.

2. Variable Frequency Output from 45–400Hz

Supports an adjustable output frequency range of 45–400Hz, including 400Hz output for compatible avionics equipment. Users can select the required frequency within the supported range to provide different AC power conditions during equipment evaluation.

3. Four Power Capacity Options

Available in four rated capacity options: 5kVA, 10kVA, 15kVA, and 20kVA. This range allows users to select a suitable power capacity according to the power consumption and operating requirements of their equipment.

4. 7-Inch Color Touchscreen

The 7-inch color touchscreen provides a clear operating interface for adjusting output voltage and frequency. It displays key operating parameters, including voltage, current, power, frequency, and power factor.

5. Programmable Voltage and Frequency Settings

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, helping simplify repeated operation.

6. Voltage Ramp Function

The voltage ramp function gradually increases the output voltage. It can be used when evaluating how compatible equipment responds to a gradual change in its AC supply voltage.

7. Multiple Protection Functions

The power source 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 an equipment 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. These technologies form part of the power conversion and output control system.

Technical Specifications

Model Selection and Dimensions

Important Notes:

• The standard output voltage is 0–300V AC. The 0–600V AC configuration is a customized option and requires confirmation before ordering.

• THD ≤2% is specified under resistive load conditions.

• Actual output current and available power depend on the selected model, output voltage, and load conditions.

• The Model 2 rated current at 120V is listed as 81.33A in the supplied specifications. This value should be confirmed because 10kVA divided by 120V equals approximately 83.33A.

• The overload cutoff values are listed according to the supplied specifications. The exact boundary conditions and operating details should be confirmed with the manufacturer.

• Please confirm the required input current, wiring, and circuit breaker capacity before installation, especially for the 15kVA and 20kVA models.

• Communication interfaces and protocols are not listed as standard features because their availability and configuration have not been confirmed.
