7. POWER FACTOR IMPROVING AC REACTOR/POWER FACTOR IMPROVING DC REACTOR
7.1 MR-J3 series Power Factor Improving DC Reactor
POINT
For the 100V AC power supply type (MR-J3-_A1) and MR-J3W series, the
power factor improving DC reactor cannot be used.
The power factor improving DC reactor increases the form factor of the servo amplifier's input current to
improve the power factor. It can decrease the power supply capacity. As compared to the power factor
improving AC reactor (FR-BAL-(H)), it can decrease the loss. The input power factor is improved to about 95 .
It is also effective to reduce the input side harmonics.
When connecting the power factor improving DC reactor to the servo amplifier, always disconnect P
1
and P
2
(For 11k to 22kW, disconnect P
1
and P). 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.
