Open-frame, convection cooled 80W power supply

The LCE80 is suited for fan-less applications as no forced air is required. This significantly enhances the reliability of the overall system while reducing system size and weight as well as simplifying mechanical design. The silent fan-less operation makes it suitable for applications where audible noise can be an issue such as office environments.

The range features a total of ten single output models covering the range 5.0V to 54.0V with efficiency levels as high as 90%. The output operates in constant voltage or constant current mode depending on the load condition, ensuring compatibility with a wide variety of applications.

An ultra-wide input range of 90 to 305VAC is offered as standard, allowing the units to operate safely at a single-phase high line of 277VAC nominal. All units in the range offer Class I and Class II operation and carry a wide range of relevant approvals including EN55032, EN55015 and EN61000-3 for EMC emissions and EN55035 and EN61547 for EMC immunity. In addition, the units are approved to EN/UL/IEC62368-1 for ITE safety and EN61347-1/UL8750 for lighting and displays.

For loads greater than 50W all LCE80 units meet the harmonic Class C limits that are necessary for lighting applications. They are also compliant with the limited power source (LPS) requirements for 12V and above, ensuring a reduced risk of fire or electrocution during operation and handling as well as fault scenarios.

Housed in a convenient and compact 4” x 2” x 1.1” (101.6mm x 50.8mm x 27.9mm) open frame format, the LCE80 units include short circuit, overvoltage and overload protection that protect the power supply and any load that it is powering.
