The automatic quiescent power cut-off receptacles(QPCR from now on) have achieved a noticeable energy saving so far. The government is preparing a new code for wider promotion of the QPCRs. This paper presents a new QPCR that adopts the latch relay instead of the conventional coil-operated relay. Measurement results of the prototype have shown up to 0.22W improvement of quiescent power compared with existing products.
