Power Factor Improving Dc Reactor - Mitsubishi Electric MELSERVO MR-J5 Series User Manual

6.12

Power factor improving DC reactor

Advantages
• It improves the power factor by increasing the form factor of the servo amplifier's input current.
• It decreases the power supply capacity.
• The input power factor is improved to about 85 %.
• As compared to the power factor improving AC reactor (FR-HAL-(H)), it decreases the loss.
Restrictions
When connecting the power factor improving DC reactor to the servo amplifier, disconnect P3 and P4. If it remains connected,
the effect of the power factor improving DC reactor is not produced.
When used, the power factor improving DC reactor generates heat. To dissipate heat, therefore, maintain a minimum
clearance of 10 cm each at the top and bottom, and 5 cm at the sides.
