The Universal Power Adapter for Mobile Devices (UPAMD) standard defines a power delivery connection between a power adapter and a power using device greater than 10 W and up to, but less than 240 W. A communications link between the power adapter and the mobile power-using device is also defined. Th...

This standard applies to surge protective devices designed for application on the low-voltage supply mains (1000 V rms and less, frequency between 48 and 62 Hz) and intended to be connected at locations between, and including, the secondary terminals of the distribution transformer and the line side...

The following enclosed low-voltage ac power circuit breakers are covered in this standard: a) stationary or drawout type of two-, three-, or four-pole construction, with one or more rated maximum voltages of 1058 V, 730 V, 635 V (600 V for units incorporating fuses), 508 V, or 254 V for application ...

Low-voltage metal-enclosed switchgearwhich contains either stationary or drawout, manually or electrically operated low-voltage ac or dc power circuit breakers in individual metal compartments, in three-pole, four-pole, two-pole, or single-pole constructionis covered. Rated maximum voltage levels ar...

This standard adopts IEC 61000-4-15:2010, which gives a functional and design specification for flicker measuring apparatus intended to indicate the correct flicker perception level for all practical voltage fluctuation waveforms. Information is presented to enable such an instrument to be construct...
