The winner for each category, and honorable mentions for the runner-up positions, were announced in February of 2017.


Wide-band Power Meter, Model WPM

The model WPM wide-band power meter measures and displays voltage, current, power, and energy parameters for single-phase or three-phase systems. Applications include measurement of PWM generated waveforms used in variable-frequency-drives (VFD's) and inverters. These units are also compliant with recent Department of Energy updates requiring 40th harmonic measurements (10 CFR Parts 429 and 431).

Local display is provided by three LED displays. Displayable parameters are grouped into four sets of three parameters each with the groups selectable by front panel push-button. Remote display modules may be added as required to provide dedicated display of up to eighteen different parameters.

Analog outputs may be provided by adding one or more D/A-4772 converters. Each of these converters provides up to eight output signals which may be assigned to any eight parameters.

Serial communications are provided through either an RS-232C, RS-422, RS-485 or USB interface, using a simple ASCII protocol. (USB is an external RS-232C-to-USB adapter.)
