The IEC Rotary Rheostat / Potentiometer is for low resistance and high power. It is useful in the classroom where larger currents are required.

Resistance is 5 ohms and power dissipation is 100 watts. This calculates to a permissible current of about 4.5 amps.

The unit is fitted with 3x 4mm spin free IEC terminals so it can be used as either a rheostat (variable resistor) or a potentiometer.

The rear of the unit is open to allow students to see the construction of a Potentiometer or a Rheostat. However when used at currents approaching 5 amps it will be dissipating up to 100 watts and it will be very hot. Always supervise its use.

NOTE: This is a genuine IEC product
