Output power is 12-24W, with output wattage being 12W on 3-5V units, 15W on 5-8V, 20W on 8-11V and 24W on 11-27V. The standard output connector is a barrel plug on a 4-foot 18AWG cable, but for flexibility, many other desired connector and output options can be accommodated as well.

Other main features of the TRM24 series of desktop power adapters are its approvals to IEC60601-1, UL60601-1, EN60601-1, CE, CB safety standards as well as its compliance with EN60601-1-2 EMC standards including EN55011/FCC/VCCI class B, EN61000-3-2, EN61000-4-2, EN61000-4-3, EN61000-4-5, EN61000-4-11. They can be fully loaded at 0°C-40°C ambient temperature. The units, which comply with CEC efficiency level IV regulation, consume very low standby power, typically less than 0.3W, and have an efficiency up to 79%. The MTBF is 150,000 hours minimum at full load at 25°C ambient temperature per MIL-HDBK-217F standards. The adapter’s approximate dimensions are 1.69 x 4.16 x 1.18 inches.

The TRM24 series of desktop power adapters offers both class I and class II insulations. Class II units come with an IEC320/C8 AC inlet without a ground pin, while class I units are furnished with an IEC320/C14 (3 flat pins) or IEC320/C6 AC (3 round pins) inlet that has a ground pin.
