Configured to supply regulated internal voltage to Field Control Units (FCU), FIO Node Units, and ESB Bus Repeaters, the device processes primary utility alternating current down to isolated direct current rails. The hardware utilizes specific backplane connectors to interface with dual-redundant power slots, driving continuous current outputs under varying thermal conditions without loss of phase synchronization.\u003c\/p\u003e\n\u003ch3\u003eHardware Specifications\u003c\/h3\u003e\n\u003cfigure class=\"table\"\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003e\u003cstrong\u003eParameter\u003c\/strong\u003e\u003c\/th\u003e\n\u003cth\u003e\u003cstrong\u003eSpecification\u003c\/strong\u003e\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003ePW482-S01\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eYokogawa\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOrigin\u003c\/td\u003e\n\u003ctd\u003eUSA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e0.9 kg (Net module weight) \/ 8.15 kg (Total shipping package weight with unit chassis)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e5.1 cm x 20.3 cm x 15.2 cm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temp\u003c\/td\u003e\n\u003ctd\u003e-10 to +55 deg C (Standard operation) \/ -20 to +70 deg C (With G3 environmental option)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Consumption\u003c\/td\u003e\n\u003ctd\u003eMaximum 230 VA input load\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Voltage\u003c\/td\u003e\n\u003ctd\u003e220 to 240 VAC nominal (+10% \/ -10% variation allowance)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Frequency\u003c\/td\u003e\n\u003ctd\u003e50\/60 Hz (+3 Hz \/ -3 Hz tolerance window)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutput Voltage\u003c\/td\u003e\n\u003ctd\u003e24 VDC regulated power rails\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutput Current\u003c\/td\u003e\n\u003ctd\u003eUp to 50 A continuous rating\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eEfficiency Index\u003c\/td\u003e\n\u003ctd\u003eGreater than 85% at nominal load parameters\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInternal Placement\u003c\/td\u003e\n\u003ctd\u003eSlots P1 and P2 in designated FCU\/FIO\/ESB chassis\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCorrosion Tolerance\u003c\/td\u003e\n\u003ctd\u003eISA G3 class validation option\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003ch3\u003eDCS Distributed Power and Channel Isolation\u003c\/h3\u003e\n\u003cp\u003eThe module architecture executes load sharing when paired in dual-redundant slot configurations, ensuring continuous 24 VDC delivery during line voltage dropouts or internal hardware failures. Built-in channel-to-channel isolation circuits decouple the high-voltage AC input lines from the sensitive 5 VDC and 24 VDC system backplane buses. The internal power logic maintains short-circuit protection and overload suppression thresholds, isolating local fault conditions to prevent grid faults from tripping adjacent digital or analog I\/O modules on the same node carrier.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: Can the PW482-S01 module be utilized as a standalone 24 VDC bench power supply for third-party industrial components?\u003c\/p\u003e\n\u003cp\u003eA: No. The unit utilizes exclusive backplane plug connectors engineered strictly for insertion into designated Yokogawa P1 and P2 chassis slots. It lacks external screw terminals for general wiring distribution and requires system backplane monitoring lines to govern active regulation loops.\u003c\/p\u003e\n\u003cp\u003eQ: How does the system manage failover logic when one redundant power module loses active AC input?\u003c\/p\u003e\n\u003cp\u003eA: The chassis backplane connects two modules in a parallel diode-OR configuration. When the primary unit loses input voltage, the secondary module immediately assumes the full current load without voltage drops or switching delays, keeping the attached processor and I\/O modules active within their operational tolerances.\u003c\/p\u003e\n\u003cp\u003eQ: What environmental conditions necessitate the selection of the G3 suffix variant over the standard version?\u003c\/p\u003e\n\u003cp\u003eA: The G3 variant features conformal coatings designed specifically to counter atmospheric contamination such as hydrogen sulfide, chlorine, and high relative humidity. It also extends the maximum continuous ambient operating ceiling from 55 deg C up to 70 deg C inside dense unventilated terminal cabinets.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSlot Insertion Alignment:\u003c\/strong\u003e Place the module strictly into designated power slots P1 or P2 of the node unit chassis. Slide the assembly along the guide channels until the rear blade pins lock firmly into the backplane mating socket.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAC Input Terminal Safety:\u003c\/strong\u003e Isolate the upstream circuit breaker before connecting the primary 220-240 VAC line cables to the chassis input terminals. Verify all protective plastic covers are snapped in place to prevent accidental contact.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeparation Restrictions:\u003c\/strong\u003e Separate the primary AC power supply lines from low-voltage DC communication links and field sensor routing channels. Maintain a minimal physical path clearance of 300 mm to suppress high-voltage noise induction.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChassis Ground Path Verification:\u003c\/strong\u003e Inspect the structural grounding terminal connecting the carrier rack to the master instrument ground grid. The total ground path resistance must measure below the maximum parameters specified by the plant safety system design manual.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Yokogawa","offers":[{"title":"Default Title","offer_id":43698680463450,"sku":"PW482-S01","price":99.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/5957\/0778\/files\/657..jpg?v=1784686329","url":"https:\/\/www.spareoil.com\/ar\/products\/power-supply-modules-yokogawa-pw482-s01-centum","provider":"SpareOil Automation","version":"1.0","type":"link"}
