With both medical and industrial safety certifications, the QM8B addresses a wide range of applications, including BF rated medical equipment, test and measurement, broadcast, communications and renewable energy. Accepting a wide range 90-264Vac 47-440Hz input, the QM8B can deliver 1500W output power or 2000W with a high line input of 180-264Vac. 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.

The units can operate in ambient temperatures of -20 to +70°C, derating output power and output current by 2.5% per °C above 50°C. The unit measures 200×63.3x268mm and the weighs from 2.3 to 3.4kg depending on the module configuration. 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. Product selection is made simple with an online configurator, giving an optimised module selection with a choice of signals, leakage current and standby voltages. Upon entering up to 18 output voltages and currents, the configurator will automatically produce a unique 7-digit code for easy order placement and quick delivery.
