{"product_id":"liftmaster-3phconv","title":"LiftMaster 3PHCONV Transformer Kit — 208\/240\/480\/575V AC Input to 120V AC","description":"\u003cp\u003e\u003cstrong\u003eThe LiftMaster 3PHCONV transformer kit adapts a supported gate operator to an approved higher-voltage supply arrangement by providing 120V AC output from the selected 208, 240, 480 or 575V AC input. Despite the three-phase wording often used in its sales name, the manufacturer specifies a single-phase transformer input rating. It does not convert the gate motor into a three-phase motor. Selection also depends on the exact operator, accessory-outlet load and available space for batteries or a heater.\u003c\/strong\u003e\u003c\/p\u003e\u003ch2\u003eCompatibility — Models, Versions and Exclusions\u003c\/h2\u003e\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eModel or selection point\u003c\/th\u003e\n\u003cth\u003eCompatibility requirement\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eListed AC operators\u003c\/td\u003e\n\u003ctd\u003eSL3000U\/UL and CSW200U\/UL, following the kit’s model-specific instructions.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eListed DC operators\u003c\/td\u003e\n\u003ctd\u003eCSL24U\/UL, CSW24U\/UL, HDSL24UL, HDSW24UL, INSL24UL and IHSL24UL.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHDSL24UL \/ HDSW24UL with 33Ah batteries\u003c\/td\u003e\n\u003ctd\u003eThe referenced kit instructions state these batteries cannot fit with this transformer arrangement.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCSL24U\/UL heater installation\u003c\/td\u003e\n\u003ctd\u003eThe referenced mounting instructions exclude simultaneous installation of the optional heater.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOther operators or supply arrangements\u003c\/td\u003e\n\u003ctd\u003eNot established as compatible; obtain the exact approved installation requirements.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003ch2\u003eCheck Electrical Selection and Cabinet Space Together\u003c\/h2\u003e\u003cp\u003eA qualified electrician must identify the supply and select the correct transformer connection using the kit instructions and equipment rating. The available building service is not permission to connect the operator directly to that voltage. The installation includes replacement rating labels because both the operator input information and accessory-outlet limits change.\u003c\/p\u003e\u003cp\u003eMechanical fit also matters. Battery placement and heater clearance vary by operator. The CSW24U\/UL arrangement requires the batteries on a separate upper tray identified as K75-37099, while the HD slide and swing arrangements have a specific 33Ah battery exclusion. Review the actual cabinet layout before ordering; a transformer that is electrically suitable can still conflict with the installed accessories.\u003c\/p\u003e\u003ch2\u003eSpecifications and Product Identification\u003c\/h2\u003e\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eDetails\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003e3PHCONV\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSelectable primary voltage\u003c\/td\u003e\n\u003ctd\u003e208 \/ 240 \/ 480 \/ 575V AC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFrequency and phase rating\u003c\/td\u003e\n\u003ctd\u003e60 Hz, single phase, per kit instructions\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSecondary rating\u003c\/td\u003e\n\u003ctd\u003e120V AC, 7.5A, 900VA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInstallation\u003c\/td\u003e\n\u003ctd\u003eModel-specific internal mounting and electrical connection\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAccessory outlet\u003c\/td\u003e\n\u003ctd\u003eReduced model-specific rating after installation; use the supplied replacement label\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003ch2\u003eBefore Ordering\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eRecord the exact operator model and existing battery and heater configuration.\u003c\/li\u003e\n\u003cli\u003eHave an electrician verify supply voltage, phase arrangement and the required protection.\u003c\/li\u003e\n\u003cli\u003eCheck the model-specific mounting drawing and any separately required battery tray.\u003c\/li\u003e\n\u003cli\u003eAccount for the new accessory-outlet rating and apply the required equipment labels during installation.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003ePackage Contents and Separate Requirements\u003c\/h2\u003e\u003cp\u003eThe manufacturer inventory includes the transformer and bracket, routing sleeve, bushing, cable ties, wire connectors, specified mounting hardware and replacement rating labels.
