Sixteenth brick DC/DC converter design suits long cable lengths
Intended for nominal inputs of 48 or 54V with possible long cable lengths and consequent voltage drops, such as microwave radio links, the PKU3913D is the latest addition to the PKU-D series of low profile, sixteenth brick DC/DC converters.
The latest module from Flex Power Modules has a 100W rated part with an extended input range down to 30V and regulated output of 12V / 8.3A. Used in applications with nominal inputs of 48 or 54 V and voltage drops, its low input drop-out voltage is an advantage to guarantee extended operation, says the company. The input range is also compatible with PoE standard IEEE 802.3af (37-57 VDC).
The PKU3913D is designed for high efficiency at lower input voltages, peaking at over 95 per cent. The parts feature pre-bias, monotonic start-up capability, remote on/off and an MTBF of 13.88M hours at 40 degrees C ambient according to Telcordia standards.
The DC/DC converters are certified to IEC / EN / UL 62368-1 for 2250V DC input to output isolation. Comprehensive protection is included against over-temperature, input under-voltage and output over-voltage, over-current and short circuits.
The PKU3913D series is housed in a 33.02 x 22.86mm footprint and is just 11.3mm high in the open-frame formats, with optional through-hole or SMT termination. It is 12.7mm high for the pinned version with optional base plate. Size and pin-out is industry-standard.
Flex Power Modules’ products are backed up by ISO 9001 / 14001 certification and technical support.
