Low-Profile DC/DC Converters

Powerbox announces the launch of a new series of power supplies for automotive applications and on-board Internet of Things (IoT). Based on a highly integrated components platform and low-profile planar magnetics the new series ENA100 (100W) and ENA200 (200W) are packaged in a plastic enclosure, which is IP21 and the boards are conformal coated to withstand high humidity, complying with the challenging environments found in the automotive industry.

To guarantee the highest levels of efficiency and reliability, the ENA100 and ENA200 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.

As members of the Powerbox Automotive Line, the ENA100 and ENA200 units have been designed in response to the automotive electronics equipment manufacturer's demand for standardised DC/DC converters built-in low profile packaging, lower than 20 mm (0.8 "), isolated cases with an IP-class of 21, 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.

Packaged in 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. The ENA100 and ENA200 series cover a large range of applications requirements from 10VDC input up to 120 VDC (10V to 18V - 18V to 32V - 36V to 75V and 55V to 120V). Four output voltages, 12.5V, 14.5V, 24.5V and 28V will be available and, depending on the output voltage, in a range of output currents of 8A to 16A. The ENA100 and ENA200 have industry leading efficiencies of up to 96%.
