What this resistor is and who uses it

This 1000W 3ohm 5% wire wound resistor fits power supplies, transducers, elevator controls, arena audio systems, lifting and braking gear, ship equipment and high requirement industrial loads. The aluminium housing provides heat dissipation and suits cooling plate installation in harsh environments.

Practical limits of the wire wound design

The component measures 33 x 6 x 3cm with a 36 x 0.5cm cable. Installation spacing pitch is ~0.6cm and terminal inner diameter is ~0.4cm. Multi connection forms allow secure fixing while the compact size handles high power load.

What to check on your existing setup before ordering

Verify that your mounting surface accepts the 33 x 6 x 3cm footprint and that the 0.6cm pitch matches your bracket holes. Confirm the 0.4cm terminal bore fits your lugs and that the 36cm cable length reaches your termination point without strain.

Questions about this item

Should I choose the 3 ohm 5% version or a different resistance value?

This listing is for the 3 ohm 5% model; other resistance values are separate products.

What does the 1000W rating mean when the resistor is mounted in my equipment?

The 1000W rating applies when the aluminum housing is fixed to a cooling plate; free-air dissipation is lower.

What connection spacing does the 0.6cm pitch terminal require on my board?

Mounting holes must match the 0.6cm pitch with 0.4cm inner-diameter terminals for the supplied cables.
