Medical power supplies feature full MoPPs isolation

The QS series has been certified to both medical and industrial safety standards and are suitable for a wide range of applications, including BF rated medical equipment, test and measurement, broadcast, communications and renewable energy applications.

Operating from a wide range 90-264VAC input, the QS is available with three standard output voltages: 12, 24 and 48V. The QS5 delivers 600W, the QS5H can deliver between 1,080-1,200W with an input voltage of 180VAC or greater and 700W below 180VAC. The QS7 is rated at 1,200W over the full input voltage range. An optional standby/signal can be selected with a choice of one or two 5V standby voltages, unit inhibit or unit enable and a PMBus interface.

Overall case dimensions for the QS5 models are 127x63.3x270mm (WxHxD) and 176x63.3x270mm for the QS7. The QS5 has an optional IEC320 input connector, in place of a screw terminal block, for quick and easy connection. 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 QS series is covered by a seven year warranty.

The units are certified to IEC/EN/UL/CSA 60601-1, ANSI/AAMI ES 60601‑1, IEC/EN 61010‑1, IEC/EN/UL/CSA 60950-1 with CE marking for the Low Voltage and RoHS2 Directives. With an input to output isolation of 4,000VAC (2 x MoPPs), 1.500VAC input to ground (MoPP) and 1,500VAC (MoPP) output to ground, the series can be used in BF rated medical equipment.

The QS has a maximum earth leakage current of 300µA, 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.
