The adapter comprehensive tester is an automatic power supply testing device that improves testing efficiency
1.Overvoltage Protection (OVP)
Simulate the output overvoltage to verify whether the protection circuit cuts off the output in time.
2. Overcurrent Protection (OCP
Force output overcurrent to detect whether the protection mechanism is effective.
3. Short-circuit Protection (SCP)
Short-circuit the output directly and observe whether the adapter can automatically recover or shut down.
4. Over-temperature Protection (OTP
Trigger the over-temperature condition through the high-temperature box or heating element to verify the protection function.
5. Input under-voltage/over-voltage protection
Test the protection response when the input voltage is abnormal.
In the performance testing of power supply products, power supply testing equipment can replace manual labor, transforming from traditional manual testing to current automated testing, thereby enhancing production efficiency. At the same time, it is committed to improving the simplicity, flexibility and wide applicability of the operation of power supply testing equipment.
Today, the manufacturing industry is experiencing rapid technological advancements, especially with increasingly higher quality requirements for power supply products, featuring high-precision and automated production processes. For this reason, Chuangrui Electronics, based on market demands and drawing on over ten years of R&D experience, has developed various testing equipment for power supply products, such as charging pile testing systems, adapter power supply testing systems, charger/power bank testing systems, and computer power supply testing systems. Inverter power supply testing systems, LED power supply testing systems, mobile power supply testing systems, industrial power supply testing systems and other testing instruments.
