Besides providing higher power over extended temperature range, the module is pin compatible and retains the same form factor as the PIM200X series for ease of upgrading to higher power or thermally challenging ATCA board designs. The PIM200X/300X series are a new class of power modules designed to greatly simplify the task of implementing dual redundant, hot swap – 48Vdc power distribution with EMI filtering on an ATCA or other telecom boards. The PIM300X, when used with a variety of GE’s dc-dc converters/POLs provides for a quick, simple and elegant power architecture solution to a wide variety of complex power requirements. While providing high reliability, innovative features and compact design at a low cost, the module significantly reduces the valuable telecom board real estate compared to conventional discrete designs. Besides processing the main –48V bus, the module greatly simplifies the task of powering the IPM (for ATCA applications), system management or other housekeeping functions by providing a completely isolated auxiliary 3.3V or 5.0V power bus. † * UL is a registered trademark of Underwriters Laboratories, Inc.

Consult Fusing and fault protection (Section 4.1.4) of PICMG 3.0 ATCA specifications for additional information. Based on the information provided in this data sheet on inrush current and maximum dc input current, the same type of fuse with a lower rating can be used.
