Value Brand 12G409 Analog Panel Meter AC Voltage 0-300V

SKU CH-HMNZ-K38CB

Analog panel meter measures AC voltage from 0 to 300 V with 1.5 % full-scale accuracy in a 2.5 inch glass-filled polycarbonate case

  • Product typeElectronic
  • Measures up to 300 V AC for high-voltage panels
  • ±1.5 % full-scale accuracy ensures reliable readings
  • Moving-iron movement needs no external power supply
  • 5 inch polycarbonate case fits standard cut-outs
  • UL listed and includes mounting template with screws

Purpose & Fit

The Value Brand 12G409 is an analog panel meter built for AC voltage monitoring up to 300 V. It suits technicians and panel builders who need a direct-reading instrument for switchgear, control cabinets or industrial equipment.

Capacity & Headroom

The moving-iron movement covers 0 to 300 AC V with an accuracy of ±1.5 % of full scale. Readings remain reliable across the stated range, while voltages beyond 300 V exceed the meter’s design limit and require a different instrument.

Upgrade Path

This unit replaces older 2.5 in panel meters that lack UL listing or use less durable case materials. The 10 % glass-filled polycarbonate case and polycarbonate window resist impact and UV exposure better than standard plastic housings. The included mounting template and screws simplify retrofit installations. Buyers who need DC measurement, higher voltage ranges or digital readouts should select a different meter type.
