Non-Inductive Resistors from Isotek

 Non-inductive resistors are designed for applications where high voltage, low inductance and good heat dissipation are required. Since 1989, ISOTEK has been building a solid reputation for quality non-inductive resistors and personal service.Non-inductive resistors from Isotek Corporation are offered in the widest selection. These resistors come in Extruded Aluminum Housings.

Isotek's non-inductive resistors are designed for applications where high voltage, low inductance and good heat dissipation are required. With resistance ranging from 0.1 Ohms to 2 mOhms, Isotek's non-inductive resistors are designed for applications with 25 Watts to 1200 Watts power requirements.

Typical applications in which these resistors are used require high wattages and limited space. As a result, they are compact in nature and their enclosure chassis are encased in good quality heat sinks. These non-inductive resistors are great in applications such as material handling and fabrication, elevators, hoists, cranes, escalators and mass transit.

With tubular Aluminum Housing and non-inductive windings, the FRH, and RH series offer resistance ranging 0.022 Ohms to 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 non-inductive resistors and personal service. 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.
