Powerbox has introduced a 100W encapsulated AC/DC power supply, ready for industrial systems integration. Aimed at compact industrial systems applications with limited space, the ENI100 has a narrow width of 31.7mm and a length of 140mm making it easy to fit in even the smallest of places. The unit’s input voltage range is from 90 to 264VAC and the output delivers a fixed 24V at 4A. Based on Powerbox’s flyback topology and proprietary ‘Always On’ regulation mode, the power supply intelligently ‘self-controls’ its output behavior to guarantee continuous operation and quick recovery in the case of a load or temperature fault. The ENI100 is CB certificated according to EN60950-1.
Powerbox’s type ENI100-5138 power supply has a nominal input of 100 to 240VAC although it can be operated with a small derating between 90 and 264VAC. The output voltage is factory adjusted to 24VDC and delivers an output current of 4A. The output is protected against over-current and short-circuit damage by a current limitation operating in ‘Always On’ mode, guaranteeing that the unit will always return to full operation after the output fault is removed. Powerbox’s ‘Always On’ technology also adjusts the available output power while taking cognizance of the unit’s internal temperature in order to keep it in a safe operating zone.
The unit is CB certified according to IEC 60950-1 and complies with related EMC standards and class B. Within the range of applications, the ENI100 can be exposed to electrical arcs and is verified to comply with the ESD susceptibility IEC61000-4-2 ±6kV contact discharge, and ±8kV air discharge. Able to be installed outdoors or exposed to a humid atmosphere (5 to 95% non-condensing) the ENI100 is designed to meet an ingress protection level of 54 (IP54). Input and output cables are fixed to the unit with crimped terminals for easy connection.
