LED2472 2000 points RMS real digital indicator has ultra compact 3/64 DIN - 24 X 72 mm size, 14 mm LED display, fast installation, DC/AC automatic or manual, direct DC power +5 V or 7.5 V to 12 V, optional AC power supply 250 VAC, IP55 front panel and IP31 housing.
The LED2472 is a 3/64 DIN (24 × 72 mm) digital voltmeter and ammeter featuring a 14 mm red LED for easy reading. It offers quick, tool‑free installation with detachable screw terminal blocks and can be powered directly from +5 V, +7.5 V to 12 V, or optionally from an isolated supply up to 250 VAC. The front panel is rated IP55 and the case IP31.
The device provides configurable measurement ranges for voltage (200 mV‑500 V) and current (2 mA‑2 A) in both continuous and RMS modes, with an accuracy of ±0.1 % (DC) and ±0.25 % (RMS). It supports optional power supplies (high‑tension AL48250, low‑tension AL1040) and a 20 A shunt (SH10020). Key performance parameters include a 40‑750 Hz frequency limit for RMS mode, 125 mA current consumption, and a temperature drift of 0.0119 %/°C.
