ULV series

Embark on a journey of engineering precision with the ULV (Vertical) Series, delivering unparalleled metal-clad wire-wound resistors designed for a myriad of applications, from motor drives to electric vehicle charging. With power capacities ranging from 60W to 500W, these resistors provide adaptable solutions, featuring an inductive resistance range from 0.1Ω up to 6.8kΩ and a non-inductive range from 0.1Ω up to 3kΩ. Highlighting exceptional tolerances of ±0.5%, ±1%, ±2%, ±5%, and ±10%, a Temperature Coefficient of Resistance (TCR) maxing out at ±260ppm/℃, these resistors ensure unwavering precision. The ULV Series, distinguished as the vertical model, is UL approved, guaranteeing compliance with stringent standards. There is also a Horizontal model available as the ULH. The robust aluminum housing provides rugged protection, ideal for challenging environments, and caters to applications like motor drives, braking and snubber, EV charging, and power sources for industrial equipment. For Non UL/CE approved, explore the IRH/IRV Series. Elevate your engineering projects with the certified precision of the ULV Series from www.raraohm.com.
