寬范圍輸入電壓
高效輸入電路自動接受交流或直流輸入電壓。120/240 V AC或125 V DC輸入電路（P0922YU）在47至63 Hz的工作頻率下提供85至265 V AC的范圍（或108至145 V DC），以滿足世界范圍內(nèi)的電源要求。24 V DC電源輸入電路（P0922YC）可接受18 V DC至35 V DC的范圍。高效密封電源效率高（P0922YU高達95%，P0922Y高達81%），可靠性高，故障率低?；谄骄娰M和負荷，他們的投資回報率（ROI）不到兩年。?廣泛的交流和直流輸入電壓?高效?功率因數(shù)校正?雙級限流?過壓關閉電路?變壓器隔離24 V直流輸出?1級，2類，2區(qū)應用?UL?，UL-C和CENELEC認證?惡劣環(huán)境下的G3等級?外部現(xiàn)場設備的電源?對流冷卻（無風扇）?帶墊圈和密封外殼?水平或垂直DIN導軌安裝?支架或壁裝孔?繼電器（C型）狀態(tài)報警輸出功率因數(shù)校正電路交流輸入的先進設計（P0922YU）提供了一個有源正弦電流曲線用于近單位控制功率因數(shù)。電流限制電源作為恒壓電源運行，具有規(guī)范中列出的最大額定負載。如果在額定25°C負載下，負載電流試圖超過最大電流的110%，輸出電壓開始向零下降，從而限制輸送到負載的電流。過載消除后，恢復正常運行。

DCS Standard 200 Series power supplies provide 24 V DC to standard 200 Series baseplates. The Model FPS400-24 is a 400 W power supply that is agency certified for use in Division 2 and Zone 2 applications. Two different input voltage power supplies are offered: ? 120/240 V AC or 125 V DC input (P0922YU) ? 24 V DC input (P0922YC). These power supplies are the only power supplies that have been tested and qualified by Foxboro DCS for use with 200 Series Fieldbus Modules (FBMs). For sites where a lower-powered and/or smaller sized solution than the FPS400-24 power supply is desired, the FPS240-24 and FPS120-24 power supplies are available. They are discussed in 200 Series Power Supplies - FPS240-24 and FPS120-24 (PSS 41H-2FPS)
Wide-range Input Voltages
A high-efficiency input circuit automatically accepts either ac or dc input voltages. The 120/240 V AC or 125 V DC input circuit (P0922YU) provides a range of 85 to 265 V AC at 47 to 63 Hz operation (or 108 to 145 V DC) to meet world-wide power requirements. The 24 V DC power supply input circuit (P0922YC) accepts a range of 18 V DC to 35 V DC. High Efficiency The sealed power supply has high efficiency (up to 95% for P0922YU and up to 81% for P0922YC) resulting in high reliability and low failure rates. They have a return-oninvestment (ROI) of less than two years based upon average electrical rates and load.? Wide range of AC and DC input voltages ? High efficiency ? Power factor correction ? Dual stage current limiting ? Overvoltage shut down circuitry ? Transformer isolated 24 V DC output ? Class 1, DIV 2, Zone 2 applications ? UL?, UL-C and CENELEC Certifications ? G3 rating for harsh environments ? Power for external field devices ? Convection cooling (no fans) ? Gasketed and sealed housing ? Horizontal or vertical DIN rail mounting ? Holes for bracket or wall mounting ? Relay (form C) status alarm output Power Factor Correction Circuitry The advanced design for AC inputs (P0922YU) provides an active sinusoidal current profile for near-unity controlled power factor. Current Limiting The power supply operates as a constant voltage source with maximum load ratings as listed in the specifications. If load current attempts to exceed greater than 110% of maximum current at the rated 25°C load, the output voltage begins to decrease toward zero, thereby limiting the current delivered to the load. Upon removal of overload, normal operation resumes.
