The unit converts a wide-range AC input into a regulated 24 VDC bus output to energize control logic, gating electronics, and auxiliary I\/O modules while providing internal overload protection against current surges.\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\u003e3BHE035301R1002\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eABB\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Type\u003c\/td\u003e\n\u003ctd\u003ePower Modules\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Voltage\u003c\/td\u003e\n\u003ctd\u003e100 to 240 VAC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutput Voltage\u003c\/td\u003e\n\u003ctd\u003e24 VDC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutput Current\u003c\/td\u003e\n\u003ctd\u003eUp to 10 A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temp\u003c\/td\u003e\n\u003ctd\u003e-20 to +60 deg C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003eStandard Unitrol module weight (approx. 0.8 kg)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Consumption\u003c\/td\u003e\n\u003ctd\u003eHigh efficiency conversion profile with internal overload protection\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003ch3\u003eDeterministic Networks and Backplane Bus Communication Velocity\u003c\/h3\u003e\n\u003cp\u003eThe power module maintains high-density voltage stability across internal backplane channels to prevent logic dropouts during grid disturbances or sudden load swings. Bus voltage regulation prevents ripple-induced propagation delays, ensuring high communication velocity for deterministically cycled control tasks across integrated PLC and excitation control cards. Onboard firmware flash compatibility remains maintained through regulated voltage execution during transient input fluctuations.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: How does the overload protection operate when output current exceeds the 10 A limit?\u003c\/p\u003e\n\u003cp\u003eA: The internal current-limiting circuit trips or folds back the 24 VDC output rail upon detecting an sustained overcurrent condition, protecting connected excitation logic cards from thermal overload.\u003c\/p\u003e\n\u003cp\u003eQ: Can the module tolerate input voltage fluctuations without interrupting the 24 VDC output?\u003c\/p\u003e\n\u003cp\u003eA: Yes, the wide input range of 100 to 240 VAC allows the module to maintain stable 24 VDC regulation during auxiliary AC bus voltage dips and brownouts.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003col\u003e\n\u003cli\u003eMounting Mechanics: Mount the module vertically on standard DIN rails or within designated Unitrol panel slots to optimize convective heat dissipation through ventilation slots.\u003c\/li\u003e\n\u003cli\u003eEarth Grounding: Connect the module chassis grounding terminal directly to the panel earth bus using a low-impedance copper conductor to suppress EMI transients.\u003c\/li\u003e\n\u003cli\u003eInput Wiring: Route 100-240 VAC main power leads through dedicated terminal blocks, maintaining physical separation from sensitive 24 VDC control lines and field communication cabling.\u003c\/li\u003e\n\u003cli\u003eOvercurrent Safeguards: Install external primary-side fuses in series with the AC input lines in accordance with cabinet short-circuit protection ratings.\u003c\/li\u003e\n\u003c\/ol\u003e","brand":"ABB","offers":[{"title":"Default Title","offer_id":53257055240501,"sku":"3BHE035301R1002","price":66.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0973\/7630\/5461\/files\/3BHE035301R1002.png?v=1786069660","url":"https:\/\/www.5gplc.com\/products\/3bhe035301r1002-abb-unitrol-1010-excitation-unit-plc-module","provider":"High Five PLC Solution Limited","version":"1.0","type":"link"}
