The LEM T5SA is designed for nominal current measurements, typically handling high currents with a compact footprint. While specific datasheets should always be consulted for the latest revisions, the defining characteristics of the T5SA generally include:
Compare the T5SA to the LEM LA 305-S (500A but solid-core) – the T5SA sacrifices minimal performance for the convenience of split-core. Compared to the LEM HXS 50-NP (lower current), the T5SA is for high-power buses. For higher currents, LEM offers the T604 series (1000A nominal). lem t5sa
Unlike open-loop Hall sensors, the T5SA uses a closed-loop compensation principle, which delivers significantly higher accuracy, lower temperature drift, and better linearity. It outputs a current signal (typically 0 to 125 mA or 0 to 250 mA depending on the specific variant and turns ratio) that is a precise replica of the primary current, scaled down for safe processing by control electronics.
