RS PRO Analogue DC Voltmeter Panel Meter Cutout 45mm x 45mm 1% Accuracy 186-2478

RS PRO 186-2478 is a high-quality analogue DC voltmeter designed for precise panel mounting applications in industrial and process control environments. This meter features a 45 mm by 45 mm cutout, allowing easy integration into control and switchgear panels inside machinery consoles. The device employs a permanent magnet moving coil movement that enables accurate measurement of DC voltage with a linear calibrated scale down to zero.

The voltmeter utilizes a knife-edge type pointer that moves through an angle of 0° to 90°, providing clear and precise readings. It can measure voltages from 15mV up to 600V DC, with a capability to measure high currents through external shunts attached to the rear. The construction includes a magnet, aluminium coil suspended on pivot points, hairspring, and a jewel mechanism ensuring long-term durability and stable readings.

The meter casing is made from moulded polycarbonate which is robust, provides protection, and offers suitability for control panel mounting. The device withstands mechanical shocks up to 15g for short pulses, and it is designed to operate reliably within an ambient temperature range of -10°C to +65°C. It is also rated IP52 for protection against dust and dripping water and is suitable for environments with less than 75% relative humidity, noncondensing.

The RS PRO 186-2478 Analogue Voltmeter complies with multiple international standards including UL 94 V-0 for flame retardance, CE marking for EMC and low voltage directives, IEC 61010 safety standards, VDE 0100-410 electrical installations approval, and ISO 20653 ingress protection standards. The meter’s overload capacity is 1.2 times its nominal voltage continuously, enhancing operational reliability.

This product is ideal for industrial automation, electrical control panels, manufacturing machinery consoles, HVAC system monitoring, and laboratory instrumentation requiring accurate DC voltage measurement. Its rugged design and wide compliance make it suitable for demanding applications in industrial and commercial settings.
