April 24, 2017 - Calex announced the expansion of the FXW range 1kW full brick series with a 48V and 53V out model. As with the other models in the series, the 24S48.21FXW and 24S53.19FXW offer an 9 to 36VDC input range making them ideal for 12V and 24V battery powered applications. The 48Vout model offers up to 21A of output current and the 53Vout model offers up to 19A of output current. Both converters are isolated input to output and boast efficiencies of up to 96.9%. The FXW’s efficiency and power density is accomplished through the use of synchronous rectification technology, electronic circuit, packaging and thermal design. The converters operate at a fixed frequency, 200kHz, and follow conservative derating guidelines.
The FXW is 2.5” x 4.7” x 0.52”H and offers thermal performance with a metal baseplate. The operating temperature range of the FXW is -40 to +105C. Optional heatsinks are available for extended temperature use. Input to output isolation is 1500VDC for all models. All models also offer trim and sense. The output voltage trim range is -40 to +10%. 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. Output ripple and noise is 150mV peak to peak for the 48Vout FXW and 140mV peak to peak for the 53Vout model. Line and load regulation for both models is 0.1%. All FXW models are protected by over current, short circuit and over temperature protection.
