Industrial Frequency Monitoring

The Value Brand 12G512 digital panel meter measures AC frequency from 20 to 199.9 Hz with an accuracy of ±0.2 percent. It suits technicians and engineers who need a dedicated readout for generator, inverter or motor-drive diagnostics in control panels.

DIN Rail Mount with Screw Terminals

The unit fits a standard 3/648 DIN cutout measuring 24 by 72 mm and includes mounting brackets for secure installation. A gray LCD shows 3-1/2 digits, while screw-terminal connections accept field wiring without special tools. Operation requires 85 to 250 V AC supply with no separate excitation needed.

Replaces Analog Panel Meters

This meter upgrades legacy analog indicators where precise digital resolution and fixed-range simplicity are preferred. The jump is worth it when a panel design demands direct 199.9 Hz full-scale reading, standard DIN dimensions and a one-year manufacturer warranty for compliance records.
