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.
Currents with the high crest factor
The biggest challenge for analyzing the standby power is the correct measuring of the currents with the high crest factor.
The high crest factors are caused by the pulsed current of the power supply units. Furthermore, input filters often produce reactive currents which can be a multiple of the active current.
In standard DAQ systems, these issues force you to set the measurement ranges much higher than required by the pure sinusoidal signal which decreased the accuracy: The high-dynamic inputs (160 dB) on the SIRIUS DAQ system with DualCoreADC technology allow having a high range and the best accuracy at the same time.
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.
