TDK Corporation (TSE 6762) announces the introduction of the 500W rated configurable TDK-Lambda brand XMS500A series of AC-DC power supplies. The series is mechanically designed for effective cooling with a low 1m\/s airflow, reducing acoustic noise. Additional features over the preceding XMS500 models include an ATX power good signal, full power at 85Vac input, extended 20ms hold-up time and compliance with EN\u00a060601-1-2 immunity.<\/p>\n
The XMS500A is certified to both medical and industrial safety standards and meets EN\u00a055011-B and EN\u00a055032-B radiated and conducted emissions in protection Class I or Class II (no earth ground wire) applications. Target applications include home healthcare, hospital equipment, imaging and clinical diagnostic systems in addition to industrial, test and measurement and communications equipment.<\/p>\n
The configurability of the XMS500A allows engineers to select from a wide range of options to optimise system design and lower cost without requiring the development of a modified standard. These options include 5V and 12V standby voltages, a fan supply voltage, case options (including a built-in fan), remote on\/off, reduced leakage \/ touch current, AC fail, and single or dual input fusing. Standard output voltages available are 12V, 24V, 36V and 48V. Additional voltages and options are also offered.<\/p>\n
Operating from 85 to 264Vac and withstanding 300Vac surges for five seconds, the series can deliver full power in ambient temperatures up to 50\u00b0C with linear derating to 50% load at 70\u00b0C. The open frame configuration measures 102x180x37mm and the U channel 107x180x39.5mm.<\/p>\n
All models are safety certified to IEC\/EN\/ES\u00a060601-1, IEC\/EN\/UL\u00a062368-1, 60950-1, designed to meet IEC\u00a061010-1 and IEC\u00a060035-1 with CE marking for the Low Voltage, EMC and RoHS Directives. The XMS500A is also in compliance with the EN\u00a061000-6-3, IEC\u00a060601-1-2, IEC\u00a061000-4 emissions and immunity standards. Input to output isolation is 4,000Vac (2 x MoPP), input to ground isolation 1,500Vac (1 x MoPP) and output to ground isolation is 1,500Vac (1 x MoPP) for suitability in B, BF and BFD (defibrillator proof) equipment.<\/p>\n
