Simpson Electric Company Panel Meters A100

The Quarktwin Technology Ltd. A100 Panel Meter is a multifunction digital instrument designed for measuring electrical parameters in both three-phase (3W and 4W) and single-phase networks. It features a three-line, four-digit ultra-bright LED display capable of showing values up to 9999. The device allows for on-site programming of current transformer (CT) and potential transformer (PT) ratios, with user-selectable CT secondary options of 1A or 5A. This panel meter measures a variety of parameters including system voltage, current, frequency, RPM, and operational hours, while also storing minimum and maximum values. It includes a limit switch with a relay for trip functions and is compliant with UL and CSA standards. The A100 operates within a voltage range of 100 to 500 VL-L and supports a power supply of 40V to 300VAC/DC. The instrument is designed for easy installation with a low back depth of less than 55mm and conforms to IP 50 or IP 65 standards for dust and water protection. It is suitable for applications requiring true RMS measurement and can handle distorted waveforms up to the 15th harmonic. The A100 is an effective replacement for multiple analog panel meters, providing a compact solution for monitoring essential electrical parameters.
