Sprint 340, 680 & 1220


Three models available in 3.4amp, 6.8amp and 12 amp versions allows an easy upgrade path for those dc drive applications requiring extra power.

A versatile range of non-isolated motor controllers for permanent magnet or shunt wound motors offered in a compact easy to use din rail mounting package r permanent magnet or shunt wound motors offered in a compact easy to use din rail mounting package.

With a footprint from just 35mm x 105mm these compact range of dc drives can easily fit into existing control panels or save space in new designs.

Easy access to drive adjustments, plug on screw terminals and the din rail mounting package mean that these controllers are quick to install, and simply clip into place without the need for further engineering.
