ification of the AMM120 means that users are not required to further test or qualify the power portion of their systems, saving time and expense. The power supply measures 160 x 76.2 x 43.7mm (6.3 x 3 x 1.72 inches), has a class-leading power density of 3.69 W/cubic inch and is one of the most powerful external units currently available with medical approvals. It has a universal AC input and delivers a single output of 12, 15, 18, 19, 20, 24, 30, 36 or 48V VDC at 85% typical efficiency under full load, minimising waste heat to enhance reliability and avoiding the need for a fan to ensure silent, maintenance-free operation. The AMM120 operates at full power at up to 40 degrees C and at least 50% power at 60 degrees C.
The AMM120 needs no minimum load and has better than ±5% total regulation. Ripple and noise are limited to 2% maximum. Overvoltage, overtemperature, overload and short circuit protection are included. Auto-recovery is provided in the case of overload. The power supply meets all major international safety and EMC specifications for medical applications. MTBF is greater than 175,000 hours (MIL-HDBK-217F).
