XP 公司(MPI-XP Power AG)日前推出150-300W 的 AC/DC 开关电源 SML150和 SML300,其中300W 电源的体积据称是目前业界同类产品种最小的产品。SML150和 SML300模块是单输出电源,尺寸为4″6″(102×152mm),适用于各种紧凑型应用。这两款器件高度为2″(51mm),采用常规 AC 输入,输入电压范围在12VDC 至54VDC 之间,可在5%范围内调节。SML300具有集成的温控风扇,该风扇仅在需要时运转,从而降低噪声和提高电源系统的可靠性;SML150可提供150W 功率并采用对流散热。这两款器件还能为系统管理提供电源故障和风扇故障信号。SML150和 SML300采用了封盖和螺丝连接的坚固封装,负载调整率和纹波噪声均在1%之内,整个 SML 范围内具有完全的过载、过压及过温保护,同时还满足有关 EMC 和 ESD 规范。
XP Corporation (MPI-XP Power AG) has introduced the 150-300W AC / DC switching power supply SML150 and SML300, of which the volume of 300W power supply is claimed to be the industry’s smallest product of its kind. The SML150 and SML300 modules are single output power, measuring 4 “6” (102 × 152mm) and are suitable for a variety of compact applications. The two devices are 2 "(51mm) high with a conventional AC input and can operate within a 5% input voltage range from 12VDC to 54VDC. The SML300 features an integrated temperature controlled fan that operates only when needed , Thereby reducing noise and improving the reliability of the power system; SML150 can provide 150W power and convection cooling. Both devices also provide power failure and fan fault signal for the system management .SML150 and SML300 using capping and screw connection Rugged packaging, load regulation and ripple noise are within 1%, with full overload, overvoltage and over temperature protection throughout the SML range while still meeting EMC and ESD specifications.
