The series, which accepts a 90-264V full range AC input, features output overvoltage, overload, and short circuit protections. The output voltage, which is factory preset to meet customer requirements, is anywhere between 3-27V, with the output voltage regulation being ±5%. Output wattage 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, but for flexibility, many other desired connector options can be accommodated as well. The customer has a choice of interchangeable plugs or fixed plugs, which include US, EU, British, Australian types. Interchangeable plugs come with an adapter body and a US, EU, UK or Australian plug kit.
The leakage current is typically 60 µA @ 264 VAC on the TRM24 series of class II power adapters. Other main features are its approvals to IEC60601-1, UL60601-1, EN60601-1, CE, CB safety standards as well as its compliance with EN60601-1-2 EMI standards including EN55011/FCC/VCCI class B (conducted and radiated emissions), EN61000-3-2, EN61000-4-2, EN61000-4-3, EN61000-4-5, EN61000-4-11. The series 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 dimensions are 81x43x36 mm or 3.19×1.69×1.42 inches, approximately.
The TRM24 series is priced at US$23.50 in OEM quantity. Lead time for samples is 3-4 weeks, while lead time for production quantity is 6-8 weeks ARO.
