Power Aging Testing Equipment

We can use it to test the stability and reliability of products such as DC power supplies and power modules under long-term and continuous load working conditions; It can also test overvoltage protection, overload protection, leakage current protection, etc., to ensure the safety of the product during the testing process; It is possible to set test parameters, control the testing process, and record and analyze test data through industrial control computers and supporting software.

Power Comprehensive Testing System

It can ensure the performance and reliability of power products under various working conditions through comprehensive performance testing, dynamic characteristic testing, protection function testing, long-term stability testing, and safety testing, thereby improving the level of quality control.

High and Low Temperature Aging Testing Equipment

It can simulate natural environmental conditions such as high temperature, low temperature, and high and low temperature cycles, and is used to test the performance and reliability of power supplies at different temperatures, ensuring that each batch of power products can meet the design requirements in terms of temperature adaptability.

1. Active PFC vs. Passive PFC

For US OEM applications, especially in industrial and medical environments, Power Factor Correction (PFC) is critical. Active PFC circuits in the S Series switching power supplies achieve power factors of 0.95 or higher, significantly reducing harmonic distortion and maximizing energy efficiency. This is vital for meeting energy efficiency standards in the United States and reducing utility costs in large-scale system deployments.

2. Thermal Performance & Derating

Industrial applications often operate in harsh environments with elevated ambient temperatures. S Series power supplies feature optimized thermal designs, utilizing high-conductivity thermal pads and robust aluminum enclosures. When designing systems, OEMs must review the thermal derating curves to ensure the power supply can deliver the necessary current at peak operating temperatures without triggering overtemperature protection.

3. Electromagnetic Compatibility (EMC)

US regulations mandated by the FCC require strict control over electromagnetic interference (EMI). Our S Series AC DC power supplies are engineered with advanced input filtering circuits to meet FCC Class B conducted and radiated emission limits. This minimizes interference with sensitive nearby electronics, such as medical sensors, wireless communication modules, and precision measuring devices.

4. High Isolation Voltage

Safety is paramount in OEM medical and industrial environments. Our power supplies offer high input-to-output isolation voltages (often up to 3000VAC or 4000VAC), providing a robust barrier that protects operators and sensitive low-voltage control circuits from high-voltage grid transients.
