DESCRIPTION
Size: 2.28in x 2.4in x 0.5in (57.9mm x 61mm x 12.7mm)
The DCHB500 series of DC/DC power modules offers up
to 500 watts of output power in a compact 2.28” x 2.4” x
0.5” industry standard half-brick package. This series
consists of single output models with a wide input voltage
range and advanced potting technology. Each model in
this series features high reliability, high efficient, low ripple
& noise, as well as protection against input under voltage,
over voltage, over temperature, over current, and short
circuit conditions. Please contact factory for order details.

NOTES
1. Add “M” to end of product model number to indicate M grade temperature range. Add –P to model number to indicate positive logic.
2. Typical input, typical output, BW=20MHz, output parallel a 0.1µF ceramic cap and 10µF tantalum cap.
3. 25%-50%-25%, 50%-75%-50% load step change, di/dt=2.5A/µs. Output add min capacitance load.
4. This series is not recommended for parallel operation.
*Due
to advances in technology, specifications subject to change without notice.
