Product DescriptionDescriptionModel: TO-3A,TO-1A,TO-1H.TO-3V,TO-VAH,TO-1VMeasuring voltage range: AC 40-500VACThree phase 3L+3N or Single phase L+NMeasurement accuracy: 1.0Installation method: railStorage temperature: -25℃~+70℃Rated frequency: 50/60HzThe Din Rail 18mm AC Voltage Meter Ammeter is a compact, high-precision detection device designed for seamless integration into electrical systems, catering to both single-phase and three-phase applications. With a wide AC voltage measurement range of 40-500V, it covers common voltages like 220V (typical for residential use) and 380V (standard for industrial setups), making it versatile for homes, factories, commercial buildings, and power distribution cabinets.Built for industry-standard installation, its 18mm din-rail design ensures quick, space-efficient mounting in electrical enclosures or control panels. The modular structure allows easy combination with other din-rail components (such as circuit breakers or contactors), simplifying system assembly and maintenance—ideal for electricians and engineers seeking organized, clutter-free setups.At the core of its functionality is the LED digital display, which delivers clear, high-contrast readings even in low-light or bright industrial environments. Unlike traditional analog meters, the digital screen eliminates parallax errors, providing precise real-time data on voltage and current. This ensures users can quickly monitor electrical parameters, detect fluctuations (e.g., over-voltage, under-voltage), and prevent damage to connected equipment like motors, appliances, or HVAC systems.
