Installation
Where V2 = DC voltage present on capacitor without load. Such
a capacitor is used to filter the straightened voltage from the
power supply and to recover energy during the motor's braking
phase.
Where: RS is the resistor value in Ohm
P is the power of said resistor in Watt
Discharge resistor
The bleeder resistor is used to drain the charge from the filter
capacitor when power is removed from the supply. This helps
in bringing the supply voltage down quickly. This resistor is
mounted directly across the filter capacitor. To calculate the
correct value and wattage use the formula below.
