The OPCT16ATL Split Core Current Transformer is a precision clamp-style AC current sensor designed for reliable current monitoring in a wide range of electrical applications. Featuring a split core design with a compact 16mm window, this transformer allows for quick and easy installation by simply clamping around an existing conductor without the need to disconnect any wiring. It supports multiple current ratio options ranging from 5A to 100A on the primary side, making it versatile for various monitoring setups. Built with a toroidal copper winding construction, it delivers accurate and stable current conversion with a transformation ratio of 1000:1. The unit is rated for low-voltage applications and boasts an impressive compressive strength of 2kV/50Hz/1min. It operates reliably across a wide temperature range of -40°F to 185°F (-40°C to +85°C), making it suitable for both indoor and outdoor environments. The single-phase autotransformer configuration outputs alternating current, ideal for use with energy meters and monitoring systems. Comes with color-coded lead wires for straightforward polarity identification.
