The new QM8 series of AC-DC power supplies extends the QM series of 700 to 1500W modular power supplies to include up to 18 outputs. Having both medical and industrial safety certifications, the QM8 addresses a wide range of applications, including BF rated medical equipment, test and measurement, broadcast, communications and renewable energy applications. <\/p>\n

\"\"<\/a><\/p>\n

The QM series operating efficiency is up to 91%, reducing internal heat losses, allowing the use of low speed, low audible noise fans for cooling. This provides an enhanced patient\/user experience and increased reliability. The QM series is covered by a seven-year warranty.<\/p>\n

Accepting a wide range 90-264Vac 47-440Hz input, the QM8 can deliver between 1200W to 1500W output power<\/a>. Available output voltages range from 2.8V to 105.6V and up to eight single or dual modules can be fitted. Optional standby\/signal modules can be specified with a choice of one or two standby voltages (5V, 12V and 13.5V at up to 2A), a PMBus™ communication interface and unit inhibit or unit enable, and an AC Good signal. <\/p>\n

The units can operate in ambient temperatures of -20 to +70\u00b0C, derating output power and output current by 2.5% per \u00b0C above 50\u00b0C. Overall case dimensions are a compact 200 x 63.5 x 270mm (W x H x D), and the weight is between 2.3 to 3.4kg, depending on the module configuration. <\/p>\n

The QM series is certified to IEC\/EN\/UL\/CSA 60601 1, ANSI\/AAMI ES 60601 1, IEC\/EN 61010 1 and IEC\/EN\/UL\/CSA 60950 1 with CE marking for the Low Voltage, EMC and RoHS2 Directives. With an input to output isolation of 4,000Vac (2 x MoPPs), 1,500Vac input to ground (1 x MoPP) and 1,500Vac (1 x MoPP) output to ground, the series can be used in BF rated medical equipment. The QM8 has a maximum earth leakage current of 300\u00b5A, while still complying with the EN61000 6 3:2007 and EN60601 1 2:2015 (curve B conducted and radiated) emission standards. The units also meet the EN 60601 1 2 and EN 61000 6 2 immunity standards.<\/p>\n

An online configurator makes product selection extremely simple<\/a>, giving an optimised module selection with a choice of signals, leakage current and standby voltages. Upon entering the desired output voltages and currents, the configurator will automatically produce a short 7 digit code for easy order placement and quick dispatch.<\/p>\n","protected":false},"excerpt":{"rendered":"
