HOBUT PANEL METER D96SD

Hobut Panel Meter D96SD – Standard 96×96 mm Industrial Moving Iron AC Analogue Panel Meter

The Hobut Panel Meter D96SD is a heavy-duty, DIN-standard 96×96 mm square moving iron analogue panel meter designed by Hobut (UK) for precise AC current and AC voltage monitoring in industrial control panels, switchgear, and distribution boards. Built with a classical 90-degree scale arc and a high-torque pivot-and-jewel movement, the Hobut Panel Meter D96SD offers real-time, instantaneous current or voltage readings without the digital lag associated with electronic displays.

As illustrated in the product image, the meter features a clean white faceplate with sharp black contrast markings, an “A” designation for AC Amperes (or “V” for Volts), and a mechanical zero-adjust screw positioned at the bottom right corner. Encased in a flame-retardant UL94V-0 polycarbonate enclosure, it is engineered to fit standard 92×92 mm panel cutouts, securing firmly with rear mounting brackets.

Key Features of the Hobut Panel Meter D96SD

• Moving Iron Mechanism: Uses true RMS responsive moving iron movement suitable for measuring non-sinusoidal and sinusoidal AC waveforms.

• Standard DIN 96×96 mm Dimensions: Fits industrial control panels with a standard 92 mm x 92 mm panel cutout.

• Class 1.5 Accuracy: Built to BS89 and IEC51 standards, guaranteeing a high calibration precision within pm1.5% of full-scale deflection.

• Front Zero-Adjustment Screw: Allows quick manual recalibration and zero-pointer alignment without opening the meter housing.

• Flame-Retardant Housing: Encased in a UL94V-0 compliant, impact-resistant polycarbonate shell for enhanced safety in high-voltage cabinets.

• Wide Frequency Compatibility: Calibrated for 50 Hz line frequency, with operational capability across a wide range of 15 to 400 Hz.

Common Applications and Industrial Usage

The rugged movement and high legibility of the Hobut Panel Meter D96SD make it a preferred choice for heavy industrial monitoring installations:

• Switchgear & Power Distribution: Integrated into main distribution boards (MDBs), motor control centers (MCCs), and generator control panels.

• Current Transformer (CT) Circuits: Operates directly or via 1 A or 5 A Current Transformers to monitor high-amp primary feeder lines.

• HVAC & Industrial Motor Panels: Monitors line currents and phase loads on large AC induction motors and compressor systems.

• Marine & Generator Sets: Provides vibration-resistant current monitoring on diesel generators and marine switchboards.

Technical Specifications

The operational limits and dimensional parameters of the Hobut Panel Meter D96SD conform to standard international low-voltage panel requirements:

Installation Guidelines and Safety Notes

Warning: Ensure that power supply cables and CT secondary loops are completely isolated before installing or servicing panel meters. Never open a CT circuit while primary current is flowing.

• Verify CT Ratios: When using a 5 A CT-operated version of the Hobut Panel Meter D96SD, ensure the dial scale matches the primary ratio of your installed Current Transformer.

• Mount Securely: Insert the meter into the 92×92 mm cutout from the front of the panel and tighten the included corner mounting clamps evenly from behind.

• Terminal Protection: Use terminal covers over the rear screw studs to prevent accidental contact with live conductors inside the electrical cabinet.
