/> Both the HPH and UCH series are isolated to 2250VDC with an open-frame construction and are designed for PCB mounting. Both series are in compliance with RoHS legislation, and have UL60950-1 and EN60950-1 safety approvals.

HPH DC/DC Converters offer a choice of fully regulated single outputs ranging from 3.3VDC to 12VDC. A wide input voltage range of 36VDC to 75VDC, combined with an industry standard pinout and package measuring 61mm x 58.4mm x 10.2mm, simplifies the use of the modules in low voltage / high current OEM applications. The new converters utilise a full-bridge, fixed-frequency topology along with synchronous output rectification that enables levels of efficiency up to 91% to be achieved. Operating temperature range is -40ºC to +85ºC. An optional baseplate further enhances thermal performance

The UCH series is offered with outputs from 2.5VDC to 15VDC and a choice of either 36VDC to 75VDC or 18VDC to 36VDC input voltages. Module footprint and installed height are identical to the HPH series. UCH series DC/DC Converters are ideal for demanding telecom, datacom and networking applications with their semi-synchronous rectifier design helping them achieve industry-leading efficiency levels of up to 92%. The standard operating temperature range for the UCH family is -40ºC to +85ºC. By using an optional baseplate, the thermal performance can be further improved.

Remote sense, output trim and primary side on/off control with either positive or negative logic are included in the design of both new product series. The design of both series provides short circuit protection and thermal shutdown, plus input under-voltage and input/output over-voltage protection.
