The PKM5000W comes in the industry-standard through-hole eighth-brick format, measuring 58.4 x 22.9 x 9.91 mm. In addition to the open-frame version of the module, an optional baseplate version is also available for applications that require conduction cooling.
The module delivers very high efficiency of typically 91.5% at 12V full load. The single output units offer the nominal outputs of 3.3, 5 or 12 VDC with maximum outputs of up to 30A and 120W. Maximum outputs of specific models in the series include: the PKB5110WPI with 3.3V, 30A and 99W; the PKB5111WPI with 5V, 20A, 100W; and the PKB5113WPI with 12V, 10A and 120W.
The PKM5000W series operates over the –40 to +110C temperature range and provides 2250 VDC input/output (I/O) isolation meeting functional isolation and 1500V basic insulation safety requirements, according to IEC/EN/UL 60950-1. Other protection features include output-over-voltage protection; input-under-voltage shutdown; over-temperature protection; and output short-circuit protection. The module also has remote sense capability, which can be used to compensate for up to 5% voltage drops between the output pins and the point-of-load.
The PKM5000W power modules are also fitted with a remote control function – with negative and positive logic options available – allowing the product to be turned on/off by an external device .
