Model EPS EP CHUCK MASTER*Control unit for permanentelectromagnetic chucks�E�Application�E�Rectifies an input from an AC power source to DC and momentarily outputs exciting current to permanent electromagnetic chucks. The automaticdemagnetization circuit is activated to reduce residual magnetism of permanent electromagnetic chucks.�E�Features�E�●The EP Chuck Master* is dedicated to permanent electromagnetic chucks and can be used for EPT, EPT-H, EPTW and EPZ-U.●The microcomputer control ensures very eff ective automatic demagnetization.●The holding power is adjustable.●Model EPS-GW (B) is of external operation type.・EPS-GW is installed inside the machine panel and EPS-GWB is installed outside the panel and both of them are equipped with a remote operation box.・Compared with the conventional type, the volume has been reduced to about a third.・The workability and operability such as wiring, fuse replacement, switchover of voltage between 200 VAC and 220 VAC and output voltage/demagnetizingtime adjustment have been improved.■ General type※The applicable models are EPT, EPT-H, EPTW and EPZ-U only. ※EPS-GW (B) 230A is used as a control unit for the connection of same models or specially ordered large chucks.�E�mm�E�En�E�]Model Power SourceRated Output Dimensions Mounting DimensionsMassOperation boxVoltage Current Width Depth Height Width Height Hole Width Depth Height CordEPS-215BSingle-phase 200 VAC�E�E0/60Hz�E�E0? 90 VDC15A 180�E�E.08�E�E30�E�E.11�E�E50�E�E.84�E�E120�E�E.72�E�E275�E�E0.8�E�E4-ρE7�E�E.27�E�E4.7kg/10.3 lb ?? ?? ?? ??EPS-230B 30A 400�E�E5.7�E�E90�E�E.48�E�E00�E�E5.7�E�E290�E�E1.4�E�E446�E�E7.5�E�E4-ρE10�E�E.39�E�E18.3kg/40.3 lb 100�E�E.93�E�E0�E�E.75�E�E55�E�E.10�E�E5m�E�E96�E�EPS-W215B40?180 VDC15A 180�E�E.08�E�E30�E�E.11�E�E50�E�E.84�E�E120�E�E.72�E�E275�E�E0.8�E�E4-ρE7�E�E.27�E�E4.7kg/10.3 lb ?? ?? ?? ??EPS-GW230A Single-phase 200/220 VAC�E�E0/60Hz�E�E30A210�E�E.26�E�E67�E�E.57�E�E80�E�E1.0�E�E45�E�E.70�E�E300�E�E1.8�E�E2-ρE7�E�E.27�E�E2 ? width 7)7.0kg/15.4 lb140�E�E.51�E�E0�E�E.75�E�E50�E�E.90�E�E5m�E�E96�E�EPS-GWB230A 213�E�E.38�E�E65�E�E.49�E�E84�E�E1.1�E�E9.0kg/19.8 lbModel EPH-LW NON-CONTACT TYPE EP CHUCK MASTER*Low magnetic force control functionEPH-LW205B�E�Application�E�The use of the low magnetic force control function enables straighteningoperations as with electromagnetic chucks.The use of the low magnetic force control function facilitates positioning ofworkpieces. (The low magnetic force control requires electricity to be suppliedcontinuously. When used with the low magnetic force control function activatedfor long hours, accuracy change due to heat generated in the permanentelectromagnetic chuck itself may slightly aff ect the machining accuracy.)�E�Features�E�These Chuck Masters enable it to control the low magnetic force (weakholding power), which is diffi cult with permanent electromagnetic chucks.When a conventional permanent electromagnetic chuck is used, it isnecessary to turn it off once and after lowering the magnetizing voltage,turn it on again in order to set a low magnetic force for straighteninggrinding operations. These Chuck Masters have a control function by whichthe power can be applied continuously only in the low output region, whichmakes it possible to fi nely and continuously adjust the low magnetic forceregion as with electromagnetic chucks. They offer a possibility ofstraightening grinding with permanent electromagnetic chucks. Workpiecescan also be positioned smoothly with the low magnetic force control.※Non-contact type Chuck Masters (with low magnetic force control) for permanent electromagnetic chucks (180 VDC version).  ※The low magnetic force control is possible when used in combination with the permanent electromagnetic chuck Model EPT-LW. ※Three types; rated output of 180 VDC-5A, 180 VDC-5A (with operation box) and 180 VDC-10A (with operation box) are available.�E�mm�E�En�E�]Model Power SourceRated Output Dimensions MassVoltage Current Width Height Depth Chuck Master Operation boxEPH-LW205BSingle-phase 200 VAC50/60HzPermanent electromagnetic: 0 ? 180 VDC (2 sec.)Low magnetic force: ±0 ? 60 VDC (continuous)5A 140�E�!E5�E�E5.51�E�!E.19�E�E230�E�E.05�E�E175�E�E.89�E�Approx. 4.7kg/10.3 lb Operated from main unit panelEPH-LWE205B Approx. 4.5kg/ 9.9 lbApprox.0.6kg/1.3 lbEPH-LWE210B 10A 220�E�!E0�E�E8.66�E�!E.18�E�E250�E�E.84�E�EApprox. 6.0kg/13.2 lbEPS-215B
