ULM Series Description

Introducing the ULM resistors, an exceptional solution meticulously designed for industrial applications with the added assurance of UL approval. Crafted with precision, the ULM series features metal-clad resistors housed in durable aluminum, engineered for efficient chassis mounting, and offering versatile power ratings from 330W to 750W in free air and 600W to 1200W when heat sink mounted.

Engineers benefit from a broad resistance range, spanning from 0.1 to 160Ω (inductive) and 0.1 to 48Ω (non-inductive). Tolerance options of ±1, ±2, ±5, and ±10 percent provide a customized solution for diverse applications. The maximum temperature coefficient of resistance (TCR) is capped at 260 ppm/°C, ensuring stability across a wide temperature range from -55℃ to +200℃.

The ULM resistors excel in braking and snubber applications, motor drives, and power sources for industrial equipment, showcasing unparalleled adaptability in diverse engineering scenarios. The added distinction of UL approval establishes the ULM series as a top-tier choice for engineers prioritizing compliance with the highest safety standards in their industrial projects.

For engineers considering a non-UL-approved alternative, the IRM series stands as a robust choice. Housed in durable aluminum and engineered for efficient chassis mounting, the IRM series offers similar power ratings and resistance options, making it a reliable solution for various industrial applications.
