Calex Manufacturing Company, Inc. has announced the release of the 24S53.19FXW dc-dc converter. Suited for battery connect applications, the converter meets the most stringent performance standards for industrial, process control and transportation applications. This model represents the final product in Calex's FXW series of dc-dc converters, exhibiting a power density of 181W/in³ over a 9- to 36-Vdc input range in a ruggedized full-brick package that delivers 1000 Watts of output power.

The 24S53.19FXW boosts the conversion efficiency and power density by incorporating advanced digitally-controlled synchronous rectification technology and case construction that optimizes thermal performance.

With a footprint of 2.5 x 4.7 x 0.52 inches, the converter operates at a fixed frequency of 200kHz and a temperature range of -40⁰C to +105⁰C. Additionally, the converter can deliver full output power without derating up to 90⁰C. Heatsink options are available for extended temperature use.

All models in the 1000 Watt FXW series feature a 4:1 input voltage range; output voltages of 12-, 24-, 28-, 48- and 53-Vdc; remote ON/OFF; remote sense and TRIM that allows users to adjust the output voltage +10% to -40%.

Mindful of battery powered applications, an ON/OFF function is available to minimize the current draw from the batteries when the converter is in the off state. All FXW models are protected by over current, short circuit and over temperature protection. The FXW series is UL60950 approved.
