宽范围输入电压
高效输入电路自动接受交流或直流输入电压。120/240 V AC或125 V DC输入电路（P0922YU）在47至63 Hz的工作频率下提供85至265 V AC的范围（或108至145 V DC），以满足世界范围内的电源要求。24 V DC电源输入电路（P0922YC）可接受18 V DC至35 V DC的范围。高效密封电源效率高（P0922YU高达95%，P0922Y高达81%），可靠性高，故障率低。基于平均电费和负荷，他们的投资回报率（ROI）不到两年。•广泛的交流和直流输入电压•高效•功率因数校正•双级限流•过压关闭电路•变压器隔离24 V直流输出•1级，2类，2区应用•UL®，UL-C和CENELEC认证•恶劣环境下的G3等级•外部现场设备的电源•对流冷却（无风扇）•带垫圈和密封外壳•水平或垂直DIN导轨安装•支架或壁装孔•继电器（C型）状态报警输出功率因数校正电路交流输入的先进设计（P0922YU）提供了一个有源正弦电流曲线用于近单位控制功率因数。电流限制电源作为恒压电源运行，具有规范中列出的最大额定负载。如果在额定25°C负载下，负载电流试图超过最大电流的110%，输出电压开始向零下降，从而限制输送到负载的电流。过载消除后，恢复正常运行。

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.
