With ripple and noise suppressed below 40 mVpp, the unit stabilizes field instrument power loops, preventing power-supply-induced noise from degrading 4-20 mA HART loop protocol signaling. This level of DC rail isolation prevents thermal and electrical offset drift across sensitive cold junction compensation (CJC) circuits in connected analog input hardware.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: What output voltage configurations does the FC-PSU-UNI2450U V2.1 support?\u003c\/p\u003e\n\u003cp\u003eA: The factory default setting is 25 VDC, with support for 25 VDC or 28 VDC output levels equipped with dual overvoltage protection circuits.\u003c\/p\u003e\n\u003cp\u003eQ: How long can the power supply maintain output voltage during a full line voltage drop?\u003c\/p\u003e\n\u003cp\u003eA: The integrated hold-up circuitry maintains regulated output power for a minimum of 100 ms at full load during input power interruptions.\u003c\/p\u003e\n\u003cp\u003eQ: What is the maximum inrush current upon applying AC mains voltage?\u003c\/p\u003e\n\u003cp\u003eA: The input stage features current-limiting circuitry that restricts peak inrush current to under 15 A.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003col\u003e\n\u003cli\u003eMount the unit securely inside the enclosure chassis using standard mounting hardware to maintain solid physical earthing.\u003c\/li\u003e\n\u003cli\u003eEnsure input AC mains power is de-energized prior to connecting conductors to the primary AC terminal block.\u003c\/li\u003e\n\u003cli\u003eObserve correct wiring polarity when connecting the 25 VDC output bus lines to downstream backplane rails.\u003c\/li\u003e\n\u003cli\u003eMaintain dedicated physical separation between AC input power lines and low-voltage DC signal cables inside cabinet trunking.\u003c\/li\u003e\n\u003cli\u003eConnect the main chassis protective earth (PE) stud directly to the central cabinet grounding bus bar.\u003c\/li\u003e\n\u003c\/ol\u003e","brand":"Honeywell","offers":[{"title":"Default Title","offer_id":52407082189096,"sku":"FC-PSU-UNI2450U V2.1","price":315.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0827\/6266\/2184\/files\/FC-PSU-UNI2450U2_53757045-424b-4e53-91ec-d06137bb1617.jpg?v=1789720661","url":"https:\/\/www.powerdcs.com\/ar\/products\/honeywell-fc-psu-uni2450u-v2-1-power-supply-unit","provider":"Power DCS Parts Limited","version":"1.0","type":"link"}
