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. 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. 

Accepting a wide range 90-264Vac 47-440Hz input, the QM8 can deliver between 1200W to 1500W output power. 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), aPMBus 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. Overall case dimensions are a compact 200×63.5x270mm. 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.
