4 Ohm 200W Non-Inductive Dummy Load Resistor

This 4 Ohm 200W Non-Inductive Dummy Load Resistor is an essential tool for any audio professional or serious hobbyist seeking accurate, interference-free testing. Designed to replace a speaker or other load during diagnostics, it eliminates the acoustic noise and electrical interference that can compromise measurements, allowing you to focus on true amplifier or power supply performance. Whether you are bench-testing a new build, troubleshooting a vintage receiver, or evaluating power supply stability, this resistor provides a reliable, consistent load without the variable characteristics of a loudspeaker.

Constructed with a non-inductive winding, this component ensures minimal reactance across a wide frequency range, making it ideal for audio-frequency testing where inductive effects could skew results. The robust 200-watt power handling accommodates sustained high-power tests, while the 4-ohm impedance matches common loudspeaker ratings for realistic load simulation. Its durable aluminium housing aids heat dissipation, and the screw terminals allow secure, low-resistance connections. This resistor is a precise, repeatable reference for verifying output power, damping factor, and frequency response, ensuring your audio equipment performs exactly as intended.
