Why Choose the Lovato DM1TMA0200 Compact Split-Core Current Transformer?
The Lovato DM1TMA0200 is a compact split-core current transformer designed for accurate current measurement in commercial and industrial electrical installations. Featuring a 200/5 A transformation ratio, it converts primary currents into a standard 5 A secondary output suitable for energy meters, multifunction measuring instruments, power analysers and protection equipment.
Its split-core design allows installation around existing conductors without disconnecting the primary circuit, making it an excellent solution for retrofit energy monitoring, electrical panel upgrades and preventative maintenance projects. This significantly reduces installation time while avoiding unnecessary downtime.
The DM1TMA0200 incorporates a compact housing with a 24 × 24 mm internal opening and is supplied complete with a 2 m prewired secondary cable for quick installation. Operating at 50/60 Hz with Class 1 accuracy and a 1 VA burden, it provides dependable current measurement for a wide range of power monitoring applications.
