7.5 MR-J4-Series Power Factor Improving DC Reactor (200 V class)
The following shows the advantages of using power factor improving DC reactor.
• 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), it decreases the loss.
When using the power factor improving DC reactor to the servo amplifier, remove the short bar across 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 release heat, therefore, leave a 10
cm or more clearance at each of the top and bottom, and a 5 cm or more clearance on each side.
