{"product_id":"plx5-digital-dc-drive-copy","title":"PLXD - Digital Stack Driver","description":"\u003cp\u003eThe PLXD is used for controlling external\u003cbr\u003e3 phase thyristor stacks for DC motors, and\u003cbr\u003epossesses all the functionality of the PL\/X\u003cbr\u003erange. It is in the same package as the PL\/X\u003cbr\u003e5 - 50 models.\u003cbr\u003eThe PLXD provides gate drive pulses for\u003cbr\u003edriving user supplied pulse transformers with\u003cbr\u003eprimary pulse current up to 1.5 Amp.\u003cbr\u003eThere are terminals to accept an externally\u003cbr\u003egenerated isolated armature current signal,\u003cbr\u003efield signal, thermal heatsink sensor switch,\u003cbr\u003eand high voltage armature voltage feedback.\u003cbr\u003eThe unit also provides a +24v supply for the\u003cbr\u003egate drive pulse transformers that is short\u003cbr\u003ecircuit protected.\u003cbr\u003eThe following stack configurations can be\u003cbr\u003edriven by the PLXD:\u003cbr\u003e1) 6 pulse 2 Quadrant bridge (6 thyristors),\u003cbr\u003eor 2 bridges in parallel (12 thyristors).\u003cbr\u003e2) 6 pulse 4 Quadrant regen anti-parallel\u003cbr\u003ebridge (12 thyristors).\u003cbr\u003eExtra stacks can be used in parallel within\u003cbr\u003ethe gate drive capability.\u003cbr\u003eAll customer control terminals are the\u003cbr\u003eplug-in screw terminal variety.\u003cbr\u003eThe PLXD can be used with up to 690v AC on\u003cbr\u003eits 3 phase auxiliary supply inputs (EL1\/2\/3).\u003cbr\u003eThe external stacks can be of higher voltages\u003cbr\u003eif required.\u003cbr\u003eThe armature voltage inputs can monitor\u003cbr\u003eup to +\/-1000 Volts DC.\u003cbr\u003eThere is an integral motor field bridge with\u003cbr\u003eindependent single phase AC supply inputs\u003cbr\u003e(EF2\/3) for controlling fields up to 32 Amps.\u003cbr\u003eThe internal field bridge supply input voltage\u003cbr\u003erating is 480v AC.\u003cbr\u003eProvision is made for providing an external\u003cbr\u003efield feedback signal and controlling an\u003cbr\u003eexternal field with user supplied primary\u003cbr\u003egate pulse transformer drivers.\u003cbr\u003eThere is a pulse transformer unit (Product\u003cbr\u003ecode LA102800) available at extra cost for\u003cbr\u003eusers who prefer not to supply their own\u003cbr\u003ecomponents. It contains all the external\u003cbr\u003einterface components required to combine\u003cbr\u003ethe PLXD with the thyristor stack and its\u003cbr\u003eassociated Accts (AC current transformers).\u003cbr\u003eIt includes 12 pulse transformer networks for\u003cbr\u003e2 or 4 quadrant bridges, an armature burden\u003cbr\u003erectifier network, and 2 pulse transformer\u003cbr\u003enetworks for an external field bridge. The\u003cbr\u003eunit is designed to be mounted on a DIN rail\u003cbr\u003eand all the interface connections are via\u003cbr\u003escrew terminals.\u003c\/p\u003e","brand":"Sprint Electric","offers":[{"title":"Default Title","offer_id":53532711158103,"sku":null,"price":1755.17,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0899\/7231\/0359\/files\/Sprint-Electric-DC-Drive-PL_PLX5-50_1.jpg?v=1744294104","url":"https:\/\/shop.sprint-electric.com\/products\/plx5-digital-dc-drive-copy","provider":" Sprint Electric Limited","version":"1.0","type":"link"}
