fitlet2 is low power Class III (EN/IEC 62368-1 Audio/video, information and communication technology) equipment that is to be powered from external DC Low Power (LPS) unregulated power supply. The external power supply ratings and unregulated voltage boundaries should comply with ones defined in specifications of the specific model. Nominal current rating (A) should be increased if external peripheral devices are to be powered by fitlet2. Compulab delivers fitlet2 with a general purpose 12V 3A AC-DC power adapter that isn’t an integral part of fitlet2 and may be ordered separately as an accessory. In case fitlet2 is powered from another power supply, user should ensure that power supply complies with fitlet2 power requirements. The power connector should meet the following requirements:
- 5.5 x 2.5mm standard barrel
- Inner contact – fork type
- “+” inner contact, “-” outer contact
Operating temperature range
Up to -40°C to 85°C*
5% – 95% non-condensing
* When ordered in industrial temperature range. Commercial and extended temperature range are also available. The power supply that ships with fitlet2 is not rated for extended temperatures. Buyer is advised to deploy fitlet2 in extended temperature with a suitable power supply.
