There are four different types of wall plugs to meet worldwide requirements: US, EU, UK, and Australian. Structured with Class II insulation, the series delivers 4 W to 7 W of continuous output power and offers a wide output voltage range of 3 V to 28 V. The units also have a low leakage current of 100 µA maximum at 264 VAC/60 Hz.

The USB port is only available on the 5 V/1 A output model while other output models are equipped with a 5 feet DC output cable and a barrel plug as standard. TRUMPower also offers many other connector options and can accommodate special requirements.

The wall mount adapters are fully protected against overvoltage, overload, and short-circuit conditions. The units can withstand 5,656 VDC from input to output. They have a minimum efficiency of 67% at full load with a standby power consumption less than 0.3 W. The adapters can operate at an ambient temperature range of -10 to +50°C. Derating is required from 100% at +40°C linearly to 75% at +50°C.

The units meet EMC standards that include EN55011, CISPR-11, FCC part 18 Class B. Additionally, the TMW7 power adapters are being certified by UL, CB, CE to UL 60601-1 and EN 60601-1 medical standards and are compliant with CEC level V, ErP Step 2 and RoHS standards.
