Testing a power supply (Part 1)Robert Hanrahan
Power-supply specifications for line and load transients describe the response of a power supply to abrupt changes in line voltage and load current. By monitoring the supply as it attempts to maintain regulation in the presence of such transients, you can observe any tendency toward output over...
A DC power supply is a device which transfers AC main power to a required DC output V/A/W rating. A good power supply should be reliable, meet all re ...

programmable loads get very loud, there is no chance of hearing the power supply on the test stand. In order to make accurate measurements of the noise levels we needed a way to separate the test unit and the programmable loads. Our solution was to build a very thick box around the unit...
Power source/sink tests (BMC-POW) USB Type-C test controller GRL developed USB Type-C test controller hardware (GRL-USB-PD-C1). It has built-in USB PD controller functionality, a power supply for testing consumers and provides connectivity to the DUT and...
Method and apparatus for power failure protection ofPower failure protection for a data processing apparatus (20) is provided by the use of a standby power module (32) which supplies power to the data processing apparatus (20) when the normal power supply is interrupted. Since damage to......
We can test and certify lead-acid, lithium and other forms of electrical, electrochemical, thermal and mechanical energy used in uninterrupted power supply (UPS) and energy storage devices. We published the first safety standard, UL 9540, the Standard for Energy Storage Systems (ESS) and Equipmen...
