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.
