CALEX Obtains UL Approval on 500W and 360W Half Brick

date: 6/1/17

Calex Mfg. Co., Inc. of Concord California announces the addition of UL certification to the 500W MXW, and the 360W MTW series. Both the MXW and MTW series are recognized by Underwriters Laboratory as meeting the requirements of UL 60950-1.

The MXW and MTW feature an ultra-wide 9-36VDC input range accommodating a variety of power sources from 12V to 24V to 28V nominal. Output voltages available for both series are 12, 15, 24 and 28VDC. All models are isolated input to output. Each series offers high efficiency, up to 95.7%, 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. Both series operate at a fixed frequency and follow conservative derating guidelines.

The package size of the MXW and MTW DC/DC series is 2.4” x 2.5” x 0.52”. All models feature ON/OFF, with a low idle current of 2mA as well as Trim. The Trim range is +/-10%. The switching frequency of both DC/DC series is 200kHz. Output voltage set-point accuracy is +/-1.5%. Turn-on overshoot is 0. The temperature coefficient for both series is 0.015%/ºC 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 for both series is 2250VDC. The MTBF for both the MXW and MTW is 5.4M hours. All models feature thermal shutdown, overvoltage, over-current, and short circuit protection, all with auto-restart. All models also feature a monotonic startup into pre biased loads.

The MXW and MTW 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.
