Publication number: 20130113498Abstract: A test device with uninterruptible power supply supplies external power to a product under test (PUT) and performing electric power tests thereon. The PUT has a processing unit, a power input end, a battery connection end, and a charging and discharging circuit. The device includes a first test port, a second test port, and a power-storing unit. The PUT is electrically connected to the first and second test ports to receive the external power through the first test port and be switchable to the second test port to selectively receive power from the power-storing unit, thereby preventing interruption of operation of the PUT. A charging voltage from the charging and discharging circuit is applied to the power-storing unit via the second test port to charge the power-storing unit. An operation-required power level of the PUT can be maintained, even if the test device receives no power.Type: ApplicationFiled: December 23, 2011Publication date: May 9, 2013Inventors: CHENG-TE LIU, CHING-FENG HSIEH
