Cosel contact-cooled AC power module range

Contact-cooled AC power supplies from 50 to 750 W will not fail even when things become particularly heated. This is because sealed modules with a cooling plate do not require any air as long as they are installed on the appropriate application surfaces.

Cosel power modules are encapsulated power supplies mounted on printed circuit boards that dissipate the heat they generate exclusively through an aluminium base plate and do not require any additional fans or special flue effects.

These heat-conductive contact surfaces can reach temperatures of up to 100°C before an integral overtemperature trip puts on the brake. The power modules are designed for permanent operation under full load in 24/7 mode.

The TU series of single modules requires an external EMI filter to attenuate line-based faults. The supply range begins with the 50 W module on a ¼-brick space of 37 x 59 mm with a height of 12.7 mm. The range extends from 100 to 300 or 500 W in a full-brick format.

The TUNS basic versions have safety shut-offs as standard for overvoltage, overcurrent and overtemperature as well as a settings range for output voltage and additional remote sensor connections to compensate for voltage drops in the output cables.

The most powerful version with a permanent output of 500 W also has an additional peak power potential.

The current range of DPG/DHS modules has been extended with a plug-and-play-enabled option for the SNDPG module and the SNDHS series. The power modules can be supplied on complete assemblies in the form of a printed circuit board with a filter, fuse and plug or screw connectors on an aluminium base plate.

The user has to only complete the mechanical assembly using the 3 mm thick base plate. This means that robust CE- or UL-compliant AC power supplies with an output of up to 750 W can be produced in minutes. Output modules with 50, 100 or 250 W are supplied from an AC front-end module to correct harmonics with floating output voltages between 3.3 and 48.
