�E�Application�E�Designed for moving and transporting workpieces that have a doughnut shape orconcave part in the center�E�Features�E�●The employment of a cross-type magnet enables one unit of the Lifma tomove and transport workpieces that have a doughnut shape or concave partin the center that used to require several units of the Lifma.●Capable of transporting fl at steel plates and specifi ed-length steel plates also.Control unit required additionallyModel KR-A.P / RH-MW RECTIFIER FOR ELECTROMAGNETIC LIFMA*Model LBB UNINTERRUPTIBLE POWER SUPPLY�E�Application�E�These units rectify an input from an AC power source to DC and output it to theelectromagnetic Lifma. All electromagnetic Lifmas require the use of a rectifier.Three models are available; KR-P, A, RH-MW. Select a suitable model according toyour purpose of usage.When workpieces with a flat attractive face or made of material which tends to retainresidual magnetism such as FC are lifted, it is diffi cult to release them only by turningoff the power. In such a case, they need to be demagnetized to cancel the residualmagnetism.In some cases, the installation of an uninterruptible power supply (UPS) isrequested for use of the electromagnetic Lifma as a safety measure in the eventof power failure. This UPS needs to be fabricated according to types of rectifi ersand required output capacity. Please consult with us in advance.※The cooler is of fl uorocarbon-free type. For more information, please contact us.�E�Features�E�●The voltage can be varied in a range of 0 to 180V.●External control input terminals are provided.●An overcurrent protection function is incorporated.■RH-MW ■Connection diagramPower source UPSPower sourceRectifier LifmaUPS LMU-SRD、EH-MW205B、E、EH-MW210B〉FanCooling finBlank cap Blank cap�E��E��E��E��E��E� �E��E��E��E��E��E��E��E��E��E��E��E��E��E��E��E��E� �E� 注意－－－－－－－－－－－－－－－１２３！E�E�E�E�７８９！E�E�０１２３！E�E�E�E�７８９！E�E�０Ｐ�E��E��E��E� �E��E��E��E��E��E��E��E��E� �E��E��E��E�Ｄ�E��E� �E��E��E��E�Ｍ�E��E� �E��E��E��E��E��E��E��E��E��E� �E��E��E�，Ｌ�E��E� �E��E��E��E��E�6(73) 150(62)140190220250270290138175(17)�E��E��E��E��E��E� �E��E��E��E��E��E��E��E��E��E��E��E��E��E��E��E��E� �E� 注意－－－－－－－－－－－－－－－１２３！E�E�E�E�７８９！E�E�０１２３！E�E�E�E�７８９！E�E�０Ｐ�E��E��E��E� �E��E��E��E��E��E��E��E��E� �E��E��E��E�Ｄ�E��E� �E��E��E��E�Ｍ�E��E� �E��E��E��E��E��E��E��E��E��E� �E��E��E�，Ｌ�E��E� �E��E��E��E��E�5(73) 15080110140230250260138 (18)175LM-X800RH-MW205BKR-P203�E�mm�E�En�E�］�E�mm�E�En�E�］※External operation is necessary for ON/OFF.

Repair it periodically. Precaution for use ●The rectifier KR Series and RH Series use electronic PC boards and small relays insidethe rectifiers and therefore, are not suitable for use, for example, on cranes where they aresubjected to vibrations constantly. For installation in places that are subjected to constantvibrations, anti-vibration measures need to be provided. The external signal input cablesmust be shielded cables and must be limited to 10 m long max.●For failures due to use of lifting magnets made by other manufacturers, we may not beable to answer technical questions. Such use also voids the warranty even if a failureoccurs within the warranty period.A special size is also available.Keep in mind that the capacity of the Lifma varies largely depending on thethickness and material of workpieces, clearance and other factors.LMU-SR / LM / LM-X / KR-A・P / RH-MW / LBB100LIFTINGMAGBORE* MAGNETCHIP & SLUDGECONVEYANCE EQUIPMENTENVIRONMENTALEQUIPMENTMAGNETIZER ANDDEMAGNETIZERMAGNETIC EQUIPMENTFOR CONVEYANCEMAGNETICSEPARATORSMEASURINGTOOLSPOWERFUL MAGNETICSEPARATORSMEASURINGINSTRUMENTSMAGNETICMATERIALSMAGNETIC TOOLS & EQUIPMENTFOR WELDING OPERATION
