The fixed AC plug version meets IP22 rating. Structured with Class II insulation, there are four different types of wall plugs to meet worldwide requirements: US, EU, UK, and Australian. The units also have a low touch current of 10µA at 264 VAC/60 Hz. It comes with a USB type A receptacle on the case or moulded output cable with mini or micro USB type A or B plug.
The wall mount adapters are fully protected against overvoltage, over-current, and short-circuit conditions. The units can withstand 4000VAC from input to output with two MOPP. With a typical efficiency of 75% and 0.3W maximum no load power consumption, they are compliant with CEC level V and ErP step two.
The adapters can operate at an ambient temperature range of -10 to +60°C. Derating is required from 100% at +40°C linearly to 50% at +60°C. It has an MTBF of 300KHrs minimum at full load, 25°C ambient, calculated per Telecordia SR-332.
The TMW7 series is approved by UL, cUL and TUV to the latest medical standards, including IEC/EN/UL 60601-1 Edition 3.1, ANSI/AAMI ES 60601-1: 2012, CSA C22.2 No. 60601-1: 2014.
