AC Test Power Supply ANFH(F): Efficient Solution for EOL of Home Appliance

As competition in the global home appliance market intensifies, consumers are increasingly demanding product reliability and safety. End-of-Line (EOL) testing, the final quality checkpoint before home appliances are shipped from the factory, directly impacts a company's production costs and market reputation. Traditional power supply testing methods suffer from low efficiency, insufficient accuracy, and difficulty simulating complex power grid environments. However, the AC test power supply ANFH(F) is becoming the preferred solution for home appliance manufacturers due to its high accuracy, fast response, and intelligent testing capabilities. This article will delve into:

1. Market trends and challenges in home appliance EOL testing

2. Pain points of traditional testing methods

3. How does the ANFH(F) AC test power supply improve EOL efficiency through technological innovation?

4. Practical application cases and benefit analysis of ANFH AC test power supplies

Market Trends and Challenges in Home Appliance EOL Testing

1. Testing Complexity Brought About by Global Production

When home appliances are exported to different countries, they must adapt to local power grid standards (e.g., China's 220V/50Hz, the United States' 120V/60Hz, and Japan's 100V/50Hz/60Hz). Traditional test equipment cannot quickly switch parameters, resulting in extended testing cycles and impacting delivery efficiency.

2. Increasingly Stringent Energy Efficiency Regulations

Energy efficiency standards such as the EU ErP Directive and China's GB 21455 require home appliances to maintain high efficiency across a wide voltage range (e.g., 85V-265V). Traditional manual testing cannot cover all operating conditions.

3. New Testing Requirements for Smart Home Appliances

Smart refrigerators, air conditioners, and other devices must maintain stable operation despite grid interference (e.g., harmonics and voltage sags). Traditional power supplies cannot simulate the complex fluctuations of a real grid.

4. Accelerating Production Cycles: Create a Bottleneck for Testing Efficiency

Modern home appliance production lines can run at speeds of 10-20 seconds per unit. Excessive testing times can lead to line congestion and increased labor costs.

Pain Points of Traditional Testing Methods

1. Inefficient Manual Testing

• Relying on manual adjustment of the voltage regulator, testing a single unit takes over 30 seconds and is prone to errors.

• Inability to automate data recording, making quality traceability difficult.

2. Incomplete Test Coverage

• Only tests rated voltage, ignoring extreme operating conditions (such as low-voltage startup and high-voltage surges).

• Inability to simulate real-world interference, such as grid harmonics and frequency drift.

3. Inadequate Equipment Reliability

• Mechanical voltage regulators have a short lifespan, and frequent repairs impact production continuity.

• Lack of overload protection can easily damage the device under test due to short circuits during testing.

• Wide-Range Output: 80V-300V Voltage, 40Hz-70Hz Frequency, with one-click switching to various national grid parameters.

• Fast Response: Voltage adjustment time <20ms, meeting the demands of high-speed production lines.

2. Simulates Real-World Grid Interference, Improving Product Robustness

• Harmonic Injection: Supports superposition of harmonics from 0th to 50th order, testing the interference immunity of home appliance control panels. • Voltage swell/sag: Simulates transient fluctuations such as lightning strikes and motor startup (e.g., 220V → 0V → 220V, lasting 100ms).

3. Automated testing integration, increasing efficiency by 300%

• PLC/SCADA linkage: Connects to the production line control system via Modbus/TCP protocols, enabling unmanned testing.

• Preset test scripts: Complete multiple operating condition cycles (e.g., rated voltage → low voltage → high voltage → power outage recovery) within 10 seconds.

4. Data traceability

• Real-time recording: Stores data such as voltage, current, and power, supporting export to Excel or MES systems.

ANFH AC test power supply practical application cases and benefit analysis

Case 1: Final inspection of a variable-frequency air conditioner production line

• Challenge: Air conditioners must operate stably within the 100V-264V range, and manual testing takes 45 seconds per unit.

• ANFH AC test power supply solution: Automatically performs five voltage condition tests (100V/150V/220V/264V/sag test). =O Single-unit test time reduced to 12 seconds, increasing production capacity threefold.

• Results: Annual labor cost savings of 500,000 yuan, and an 18% reduction in after-sales failure rates.

Case 2: Smart Oven Energy Efficiency Certification Testing

• Challenge: EU ErP requirements require standby power consumption to be less than 0.5W, but traditional equipment cannot accurately measure μA-level currents.

• ANFH Solution: Uses 1mA high-precision current detection to identify standby circuit leakage issues;  Automatically generates test reports compliant with IEC 62301 standards.

• Results: Passed CE certification in one go, reducing time to market by two months.

Future Outlook: The Role of ANFH AC Test Power Supplies in Smart Factories
