Two new low profile DC-DC converters are the start of a new series aimed at connected devices in automotive applications.

The automotive industry comprises of a large segment of varying applications, requiring flexible power solutions which deliver stable voltages, immune from line disturbances, to a growing number of connected devices and Internet of Things applications. From geo localisation systems installed in a fleet of vehicles, to latest generation of busses equipped with video-on-demand per seat and high speed internet connections, the automotive industry is requiring new generations of power supply technology, simple to install, operate and in a standardised packaging.

The ENA100 (100W) and ENA200 (200W) from Powerbox in Sweden are based on a highly integrated components platform and low-profile planar magnetics in an IP21 plastic enclosure. The boards are conformal coated to withstand high humidity for the challenging environments found in the automotive industry.

To guarantee the highest levels of efficiency and reliability, the ENA100 and ENA 200 power stage uses specific components selected for robustness and high-reliability data and operated within a safe-band area. The series comes with galvanic isolation of 500VDC and built-in protections and filtering, making products ready to use without additional components.

The 18mm high modules include galvanic isolation, low conducted and radiated EMI and sustaining 2kV surges along with a requirement for simple installation and the ability to upgrade when more power is required, if new equipment is added.

"Emergency vehicles and new long-range bus fleets are requiring very flexible and reliable power sources to supply local voltages to demanding applications such as radio localisation and on-board video systems" said Patrick Le Fevre, Powerbox Marketing Director, "The new ENA100 and ENA200 series have been designed with ease of use and reliability in mind, making these class leading products."

Packaged in a 116 x 88 x 18 mm (4.57 x 3.46 x 0.70 inches) polycarbonate housing, the ENA100 and ENA200 baseplate includes four mounting holes for mechanical attachment to a vehicle chassis or assembly plate. The low weight, less than 500 grams, contributes to excelling performances in vibration testing (5-50 Hz, acceleration ±7,35m/s2 ).

Input and outputs of the products are equipped with 6.3 mm industry standard connectors, along with an integrated LED, indicating the state of the output voltage.
