Hobut D96SD Moving Iron AC Ammeter Panel Meter

The Hobut D96SD is a high-precision, industry-standard $96\text{ mm} \times 96\text{ mm}$ square analogue panel meter designed for accurate measurement of alternative current (AC) levels in industrial power networks and distribution control boards. Engineered with a robust moving iron movement mechanism, this panel instrument offers heavy-duty durability capable of handling momentary electrical inrush currents without losing calibration. Housed in a flame-retardant polycarbonate case, the D96SD provides clear, long-distance legibility for plant operators tracking central phase currents, substation loads, or primary motor draws.

Key Features

True RMS Moving Iron Operation: Utilizes a high-torque moving iron deflection system designed to register true RMS values accurately, regardless of harmonic distortions or non-sinusoidal waves on the monitored AC power line.
Standard Industrial Form Factor: Molded to a standard $96\text{ mm} \times 96\text{ mm}$ square bezel profile, facilitating seamless integration into prefabricated DIN-standard switchgear panel cutouts.
High Inrush Overload Capacity: Built to withstand standard short-duration overload peaks (such as motor startup current spikes) up to several times its normal operating current scale without physical damage to the internal needle assembly.
Optimized Visual Clarity: Features a high-contrast white dial background, bold black numbering, a crisp knife-edge pointer pointer, and a linear scale sweep layout optimized for accurate parallax-free reading.
Robust Mounting System: Equipped with secure rear-panel screw terminals and heavy-duty corner-mounting brackets to lock the unit firmly into the enclosure panel wall against ongoing plant vibration.
