Design Development, LLC supplies a wide range of essential meter accessories -- not only for the WILBAC™ series of analog panel meters, but also for other meters and applications, as well.
Our C-series and E-series meters accommodate a wide range of currents and voltages, through the efficient use of shunts (for DC current) and transformers (for AC current).
For details, select the appropriate topic below.
DC Shunts allow the sampling of very high currents and voltages, without requiring that the full energy be routed through the meter.
Precision shunts from Design Development, LLC, provide you with a reliable high-precision, high-accuracy resource for tapping into, and correctly measuring, DC electricity.
Our 50-millivolt DC shunts are available in sizes ranging from 50 amps to 500 amps, in standard ranges. Additional custom ranges are available. Contact us for specific DC shunts to fit your specific purposes.
Our pass-through "donut" transformers, and other styles, enable you to safely and accurately sense AC currents and voltages, using ordinary panel meters, without tapping directly into the AC line.
Wilbac offers several different products in this line, with a wide variety of specifications. Contact us for specific AC meter transformers to fit your specific application.
