Description
Product DescriptionThe 3-in-1 AC Digital Panel Meter (AD16-22FVAH Series) is an ultra-compact, multi-functional signal indicator designed for real-time monitoring of electrical parameters. Housing a triple LED display within a standard 22mm pilot lamp chassis, this device simultaneously tracks Voltage (V), Current (A), and Frequency (Hz) without needing separate bulky meters.Constructed with flame-retardant materials and high-brightness LED matrices, it provides clear, sharp legibility even in brightly lit industrial environments. It comes bundled with a small, external split-core Current Transformer (CT) coil, making AC current measurements safe, non-invasive, and remarkably easy to wire.### Key FeaturesTriple Display Panel: Displays Voltage, Amperage, and Hertz all at once on a stacked LED grid.Wide Measurement Range: Typically measures AC 60V–500V, 0A–100A, and frequencies between 20Hz–75Hz.Compact 22mm Footprint: Standard pilot-light sizing allows it to slip directly into existing industrial control panels.External CT Coil Included: Safe current sensing via a pass-through toroidal transformer ring.## Compatibility GuideThis panel meter is a universal electrical component. Its compatibility is dictated by physical panel layouts and the structural electrical requirements of your project.### 1. Structural & Installation CompatibilityPanel Cut-out: Fits standard 22mm (7/8 inch) circular holes, matching standard industrial push-buttons, emergency stops, and pilot lights.Mounting Environment: Compatible with distribution boards, generator control panels, solar inverter mains cabinets, custom power strips, and industrial control panels (PDBs).### 2. Electrical Systems & Load CompatibilityGrid System: Strictly for AC (Alternating Current) systems. It will not function on DC grids (like standard 12V/24V battery systems).Phase Compatibility: Primarily designed for Single-Phase lines. For Three-Phase systems ($3phi$), you must install three individual meters (one for each phase line: L1, L2, L3).Current Sensing: The included CT ring accommodates standard insulated electrical wiring gauge sizes handling up to 100A max.### 3. Compatible Brands & Universal SubstitutesBecause these are manufactured under open industrial standards, they are universally interchangeable across various electrical component suppliers.
