Description
The ceramic resistor model SPLC-WR-150-400 is most often used as a braking resistor for inverter 3.7 kW — when choosing, rely on the frequency converter manufacturer's recommended resistor characteristics and calculated motor braking power. This wire-wound resistor has a resistance of 150 Ohm and a power of 400 W.
Braking resistors of the WR series are made from a ceramic tube on which wire of iron-chrome-aluminium alloy (by default) or nichrome (on request) is wound. The ceramic body serves as an insulator and heat sink, which is resistant to high temperatures and corrosion. The wire has high specific electrical conductivity, allowing efficient heat dissipation produced during motor braking.
