1000 Watt Full Brick with Extended Operating Temperature Option

Calex Mfg. Co., Inc. of Concord California announces the addition of the "-T" option on the 1000W FXW series. The "-T" option allows for extended temperature operation of the converters from -55°C to +105°C including cold start at -55°C. This option makes both series ideal for military/aerospace and hi-rel applications requiring extended temperature operation. The FXW series features an ultra-wide 9-36VDC input range accommodating a variety of power sources from 12V to 24V to 28V nominal. Output voltages available are 24 and 28VDC. All models are isolated input to output. The FXW offers high efficiency, up to 96.5%, and high power density which is accomplished through the use of synchronous rectification, advanced circuit, packaging and thermal design resulting in a compact, highly reliable product. The FXW operates at a fixed frequency and follow conservative derating guidelines.

The package size of the FXW DC/DC series is 2.5" x 4.7" x 0.52"H. All models feature ON/OFF with a low idle current of 3mA as well as Trim. The Trim range is +/-10%. The switching frequency is 200kHz. Output voltage setpoint accuracy is +/-1.5%. Turn-on overshoot is 0. The temperature coefficient for both series is 0.015%/°C typical. Output noise is 1% of Vout peak to peak. All models operate down to a no load condition. Line and load regulation is 0.15% max. Input to output isolation is 2250VDC. The MTBF for the FXW is 5.4M hours. Both models feature thermal shutdown, over voltage, over-current and short circuit protection, all with auto-restart. All models also feature a monotonic startup into pre biased loads. The FXW is backed by Calex's Five Year Warranty. All models are RoHS compliant and designed and manufactured in the USA.

Units are available from stock to eight weeks. Contact the factory for pricing.
