Operating on a wide-range input of 110-240 VAC at 47-63 Hz, the module provides a factory-set output of 25 VDC (configurable up to 28 VDC) with dual overvoltage protection circuits and an integrated hold-up time of 100 ms at full load. The unit weighs 5.7 kg and operates reliably across an ambient temperature range of -5 to +70 deg C.\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\u003eFC-PSU-UNI2450U V2.0\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eHoneywell\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOrigin\u003c\/td\u003e\n\u003ctd\u003eNetherlands\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e5.7 kg (Shipping weight: 7.0 kg)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003eStandard Safety Manager chassis power slot\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temp\u003c\/td\u003e\n\u003ctd\u003e-5 to +70 deg C (23 to +158 deg F)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Consumption\u003c\/td\u003e\n\u003ctd\u003e13 W at no load\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Voltage Range\u003c\/td\u003e\n\u003ctd\u003e110-240 VAC (47-63 Hz)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInrush Current\u003c\/td\u003e\n\u003ctd\u003eLess than 15 A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutput Voltage\u003c\/td\u003e\n\u003ctd\u003e25 VDC (default setting) or 28 VDC; dual overvoltage protection\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRipple and Noise\u003c\/td\u003e\n\u003ctd\u003eLess than 40 mVpp\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHold-up Time\u003c\/td\u003e\n\u003ctd\u003e100 ms at full load\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eEfficiency\u003c\/td\u003e\n\u003ctd\u003eGreater than 87% at 230 VAC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eApprovals\u003c\/td\u003e\n\u003ctd\u003eCE, TUV, UL, CSA, CID2\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003ch3\u003eChannel-to-Channel Isolation \u0026amp; Power Conditioning\u003c\/h3\u003e\n\u003cp\u003eThe FC-PSU-UNI2450U V2.0 integrates channel-to-channel isolation and low-noise power filtering to supply stable 25 VDC bus power to downstream analog and digital I\/O modules. With output ripple and noise suppressed to less than 40 mVpp, the power supply prevents switching noise from coupling into high-accuracy 4-20 mA HART loop protocol circuits and sensitive field instrumentation. High-frequency galvanic isolation between the primary AC input stage and DC output rails protects sensitive system microprocessors from external power grid line surges and ground loop imbalances.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: What happens to the system supply if the AC line voltage suffers a momentary interruption?\u003c\/p\u003e\n\u003cp\u003eA: The internal capacitor bank provides a hold-up time of 100 ms at full load, maintaining stable 25 VDC output voltage through brief utility sags without triggering system reset or field loop fault alarms.\u003c\/p\u003e\n\u003cp\u003eQ: How does the unit limit current draw during cold startup on AC mains?\u003c\/p\u003e\n\u003cp\u003eA: An internal inrush current limiting circuit constrains the initial AC switch-on surge to under 15 A, preventing unwanted tripping of upstream branch circuit breakers.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003col\u003e\n\u003cli\u003eMount the FC-PSU-UNI2450U V2.0 module vertically into the designated Safety Manager power supply slot, locking all mechanical chassis latching mechanisms firmly.\u003c\/li\u003e\n\u003cli\u003eTerminate the primary 110-240 VAC input wiring into the screw terminal block, observing strict Phase, Neutral, and Protective Earth (PE) terminal assignments.\u003c\/li\u003e\n\u003cli\u003eBond the module frame ground directly to the main cabinet earth bus using a short, low-impedance conductor to ensure full efficacy of the internal EMI filter and overvoltage protection networks.\u003c\/li\u003e\n\u003cli\u003eMaintain a minimum of 50 mm clearance above and below the module ventilation openings to allow uninhibited natural convection cooling across the internal heat sinks.\u003c\/li\u003e\n\u003c\/ol\u003e","brand":"Honeywell","offers":[{"title":"Default Title","offer_id":52713678111016,"sku":"FC-PSU-UNI2450U V2.0","price":315.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0827\/6266\/2184\/files\/FC-PSU-UNI2450U2_d4dc5e0e-76a5-4be0-9107-749df615f320.jpg?v=1790062422","url":"https:\/\/www.powerdcs.com\/es\/products\/fc-psu-uni2450u-v2-0-honeywell-power-supply-unit","provider":"Power DCS Parts Limited","version":"1.0","type":"link"}
