NK Technologies has redesigned and expanded its flagship line of voltage sensing products. VTR Series transducers now feature a new, easy-to-mount 36.5mm wide DIN-rail compatible enclosure and expanded models for applications up to 500V. Additional design improvements include an optional extended-duty transformer which provides for isolation voltages of up to 3500V – ideal for battery monitoring or solar applications and among the highest in the industry for similar products. Useful in detecting voltage surges, brown out conditions, and phase loss, standard features on the VTR Series include True RMS sensing, quick response time, wide temperature range and galvanic isolation. All VTR Series products are RoHS compliant with additional agency approvals pending.
