TDK Lambda adds 700 W to 1200 W models to the QM series of modular AC-DC power supplies, featuring low acoustic noise and BF ready isolation. With both medical and industrial safety certifications, the series is ideal for a wide range of applications, including BF rated medical equipment, test and measurement, broadcast, communications, and renewable energy applications.
Packaged in a 127 mm wide x 63.3 mm high x 270 mm long enclosure, these QM models can deliver 1200 W at 180 VAC to 264 VAC and 700 W with a wide range input of 90 VAC to 264 VAC. Up to 12 outputs can be configured using single and dual output modules with voltages from 2.8 V to 61.6 V. An optional standby/signal module can be selected with a choice of one or two standby voltages (5 V, up to 2 A, and 12 V at 1 A), unit inhibit or unit enable, an AC Good signal, and a PMBus™ interface.
The units will operate in ambient temperatures of -20°C to +70°C, derating the output power and output current by 2.5% per °C above 50°C. The QM operating efficiency is up to 91% and as internal power loss is reduced, a low speed low audible noise fan can be utilized. This provides an enhanced patient/user experience and increased reliability as less dirt and contaminants are drawn into the power supply.
The units are certified to IEC/EN/UL/CSA 60601-1, ANSI/AAMI ES 60601-1, IEC/EN/UL/CSA 60950-1, designed to meet IEC/EN 61010-1, and have the CE marking for the low voltage and RoHS2 Directives. With an input to output isolation of 4,000 VAC (2 x MOPPs), 1,500 VAC input to ground (1 x MOPP), and 1,500 VAC (1 x MOPP) output to ground, the series can be used in BF rated medical equipment. The QM series has a maximum earth leakage current of 300 µA, 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 EN60601-1-2 and EN61000-6-2 immunity standards.
Product selection is optimised and simplified through the use of an on-line configurator found on the Digi-Key website which offer a choice of output, signals, leakage currents and standby voltages. Once the desired selection has been made, the configurator will automatically produce a short 7-digit code and can be submitted for quote and lead time.
