EPS-65 series – open-type AC/DC converters of medium power from MEAN WELL


The creation of electronic devices and devices requires a clear understanding of the operating conditions, which determine a set of requirements for both the power source and the housing of the entire device, where the components will be placed. In some cases, it is advisable to use an embedded power supply unit (for example, an AC/DC converter) of an open type – for better cooling and/or minimizing space occupied. To solve this problem, MEAN WELL produces various series of open-type power supplies.

The EPS-65 series AC/DC converter is a power supply unit in the form of a ready–made device - a printed circuit board with installed components and cooling radiators. The input power supply and output removal are carried out through connectors on the converter circuit board, which allows convenient and aesthetic installation of power wires inside the device body without additional adapter connections, while the assembly becomes more technologically advanced and convenient for industrial production. The mating parts of the EPS-65 connectors are not included in the delivery package and are purchased separately.

The EPS-65 series power supplies have a rated output power of 65W, which allows them to be classified as medium-power power supplies (average for embedded applications). The EPS-65 power supplies are designed for use in an AC network in the full voltage range from 90 to 264V, or in a DC power supply circuit from 127 to 370V. The output voltage is also represented by a wide range of acceptable values: 3.3, 5, 7.5, 12, 15, 24, 36, 48V DC.

The EPS-65 series power supplies are characterized by high reliability, low cost, high efficiency and cooling due to natural ventilation. The converters have all the basic protection against failure – short circuit, overload, overvoltage. The input and output connectors in the power supply are used from the manufacturer JST, information on which is given in the Specification for the EPS-65 series (in detail on the connectors on our website):

There is a separate modification of the EPS-65 series power supplies with a metal protective casing for installing the power supply in various equipment with partial access, for example, in mounting cabinets and racks. This modification is encoded with an additional letter –C in the name of the power supply:
