Industrial AP-201A-11 Digital Panel Meter For DC Voltage Measurement

AP-201A-11 is a compact 24×48 mm digital panel voltmeter for DC voltage measurement, delivering a 3-1/2-digit display with a full-scale range of ±199.9 mV and a 100 μV resolution. It is powered from DC 5 V ±5% and mounts in a standard 24×48 mm DIN panel opening with a one-touch installation. The input stage presents 100 MΩ input impedance and provides an input protection rating of ±100 V, making it suitable for precise reads on low-voltage DC rails. Overall, the unit measures 24×48×73 mm and weighs about 40 g, with a 10.2 mm high display for clear visibility. Operating conditions are 0–50 °C and 35–85% RH, ensuring reliable readings in typical lab or industrial environments. This AP-201A series device is designed for DC voltage measurement in compact instrumentation panels, power supplies, and control panels where a small, high-precision voltmeter is required.
