Isotek Metal Clad Braking Resistors - High Power 

Braking Resistors from Isotek are High Powered

Braking resistors from Isotek are offered in a wide range of HIGH POWER / Dynamic Braking Metal Clad Configurations. These resistors come in aluminum Extruded Aluminum Housings and available with standard and Non-Inductive windings. The ULH and ULV series are UL and TUV recognized.

With resistance ranging from 0.1 Ohms to 2 Mega Ohms, Isotek's braking resistors are designed for applications with 25 W to 1200 W power requirements. Most applications in which these resistors are used require high wattages where space is at a premium. As a result, they are compact in nature and their enclosure chassis are encased in good quality heat sinks. These braking resistors are great in applications such as material handling and fabrication, elevators, hoists, cranes, escalators and mass transit.

With a tubular Aluminum Housing, standard and non-inductive windings, the FRH, and RH series offer resistance ranging 0.1Ohms to 2.2 mOhms. If you are looking for Flat Stamped Housing resistors, Isotek offers IRS, IRN, and IRF series offering resistance range 1 to 5.78 KOhms.

Dynamic Braking 400 W to 3000 W

The IRP series of resistor assemblies are designed to handle power of up to 3,000 watts in free air. These packages are comprised of multiple resistors assembled into a rugged protective case. The base is made using zinc plated steel. The ventilated cover is made with powder-coated steel and is baked for durability.

Dynamic Braking 80 W to 400 W

The RA series of resistor assemblies are designed for use in power inverters and motor drives. These assemblies are based on our standard metal clad resistor technology. The resistors are enclosed in a powder coated steel case, which conforms to international safety specifications.

Dynamic Braking 60 W to 500 W (UL® Recognized)

The ULV (V=vertical) & ULH (H=horizontal) models are UL® recognized metal-clad, high power resistors designed for industrial drives and other applications. The rugged extruded aluminum housing provides electrical isolation and simple two-screw mounting. These models are available with flying leads or tab terminals and can be ordered with inductive or non-inductive windings. Packages 200W and larger are also available with internally mounted, UL listed, thermal protection circuits.

Dynamic Braking 50 W to 500 W (UL® Recognized)

The ULN and ULF models are wire-wound, high-power, metal-clad low inductance resistors designed for industrial and other applications where space is at a premium and performance is a must. The extruded aluminum housing provides rugged and strong protection while the flat design allows for excellent heat dissipation. These models are supplied with flying leads. The most common applications for these models are motor drives, dynamic braking, snubber circuits and power sources for industrial equipment. Both models are recognized UL508 components.

Since 1989, Isotek has been building a solid reputation for quality resistors. Backed by more than 25 years of sales experience and an expanded line, Isotek is now able to offer a wider range of solutions with cost-effective precision products.
