Designed for reliable operation in single phase electrical installations, with a wide input range and precise voltage sensing. Key benefits Versatile power input: accepts 170 to 277 V AC, enabling use across many regional mains without a dedicated model. Accurate sensing: voltage sensing covers 170 to 277 V on a single phase, with tolerance of ±10% at 50/60 Hz. Wide frequency compatibility: supports 50 Hz and 60 Hz environments, suitable for both commercial and industrial applications. Simple integration: built to monitor and react to voltage within a standard singlephase range, helping protect downstream devices and enable appropriate control actions. Specifications (consistent with original data) Power supply voltage: 170–277 V AC Frequency: 50/60 Hz Range tolerance: ±10% of range Voltage sensing: singlephase, 170–277 V AC Sensing tolerance: ±10% at 50/60 Hz 23 use scenarios Scenario 1: Building automation and control panels Use in a singlephase automation panel to monitor mains voltage and ensure connected relays or controllers operate only when voltage is within the specified range, improving reliability and safety. Scenario 2: International equipment deployment Deploy in equipment globally that requires operation from a wide AC input. The 170–277 V range and 50/60 Hz compatibility support diverse regional mains without the need for multiple models. Scenario 3: Industrial electrical sensing Incorporate in industrial sensors or power management modules that need accurate, singlephase voltage sensing over a broad input range to trigger voltagebased controls or safety interlocks.
