Standby PowerPower Consumption Testing on Electronic Devices

Standby power testing

One important pillar for reducing global energy consumption is increasing energy efficiency. The reduction of the standby power consumption of electronic devices is a big step towards more energy efficiency and is defined in the international standard IEC 62301.

There are several requirements for the measurement of standby power. Measurement devices have to be able to measure very low currents (< 1mA) and very low power with specified accuracy (< 0.5W with the accuracy of 0.01 W > 0.5 W with the accuracy of 2%).

Harmonic analysis up to the 49th order (2.5 kHz) is required and data logging capability is strongly recommended. For the testing process, it is also necessary to measure the voltage of the power supply, the THD, the temperature, etc. which all have to be within specified limits.

Dewesoft power analyzer meets these criteria and can measure and analyze all the parameters automatically.

Any current, highest accuracy

It’s possible to measure any kind of current without compromises. The DualCoreADC technology on the SIRIUS DAQ system uses two 24-bit AD converters per channel in parallel.

One of them measures the full input range and the other only 5% of the range. This results in the highest possible accuracy for both, the high and the low amplitude parts of the signal in one measurement.

This unique technology is revolutionary for standby power measurement and reaches accuracies never seen before.
