MELSERVO-J4

Options/Peripheral Equipment

Power Factor Improving DC Reactor (FR-HEL, FR-HEL-H, MR-DCL) This boosts the power factor of servo amplifier and reduces the power supply capacity. Use either the DC reactor or the AC reactor. As compared to the AC reactor (FR-HAL or FR-HAL-H), the DC reactor (FR-HEL or FR-HEL-H) is more recommended since the DC reactor is more effective in power factor improvement, smaller and lighter, and its wiring is easier. (The DC reactor uses two wires, while the AC reactor uses six wires.) A-RJ A B-RJ B GF-RJ GF
