Metal Wound Resistor 50W 15 Ohm

The Metal Wound Resistor 50W 15 Ohm is a wirewound power resistor with a resistance of 15 Ω and a power rating of 50 W, built into a metal housing that passes heat to a heatsink or metal chassis. It handles a large amount of power for its size, which makes it useful for dummy loads, braking resistors, battery discharge tests and power electronics experiments.

Metal Wound Resistor 50W 15 Ohm Specifications

• Resistance: 15 Ω
• Power rating: 50 W (with suitable heatsinking)
• Type: wirewound power resistor in a metal housing
• Maximum current at 50 W: about 1.8 A (I = √(P / R))
• Maximum voltage at 50 W: about 27 V across the resistor (V = √(P × R))
• Polarity: none

Metal Wound Resistor 50W 15 Ohm Applications

• Dummy loads for testing 12 V and 24 V power supplies, chargers and converters
• Braking resistors for small motor drives
• Discharge and capacity testing of batteries
• Load resistors in automotive and LED lighting circuits
• Heating and power electronics experiments in labs

What's in the Box

• 1 × 15 Ω 50 W metal-housed wirewound resistor

Tip: At 12 V this resistor draws 0.8 A and dissipates about 9.6 W; at 24 V it draws 1.6 A and dissipates about 38 W. Metal-housed power resistors reach their full rating only when bolted to a heatsink with thermal paste, so without one keep the power much lower and allow for a very hot case.
