DESCRIPTION

The LDM30AV1D0XX is a 3-digit plus dummy zero microprocessor-based digital panel meter designed for TRMS AC current and voltage measurements with 112 selectable primary ranges. It features a 1A/100V AC rated input (45 to 400 Hz), DIP-switch-selectable input ranges and decimal point positions, and a 7-segment red LED display with 14.2 mm character height providing 2 measurements per second refresh rate. The instrument offers ±0.5% F.S. accuracy (±1 DGT from 5% to 120% F.S.), operates over 0°C to 50°C, and includes overload protection with continuous rating of 1.2× rated input and 1-second peak rating of 5× current or 2× voltage. With front dimensions of 48 × 96 × 83 mm (1/8 DIN housing), IP 50 front protection degree (IP 65 on request), and power supply options of 24/48 VAC or 115/230 VAC, this meter is ideal for industrial panel mounting applications requiring reliable AC measurements in control systems, power monitoring, and electrical distribution equipment.
