description
With up to 120 watts of output power, the MOR Series™ of DC/
DC converters operates from a standard 28 volt bus and offers
a wide input range of 16 to 40 VDC. Full operation over the
military temperature range, -55°C to +125°C, makes the MOR
Series an ideal choice for military, aerospace, space, and other
high reliability applications. In compliance with MIL-STD-704D,
the converters will withstand transients of up to 50 volts for up
to 120 milliseconds. Use Interpoint’s FMCE-1528 EMI filter to
meet the requirements of MIL-STD-461C CE03 and CS01 and/or
MIL-STD-461D, E and F CE102 and CS101 levels of conducted
emissions.
The converters are offered with standard screening, “ES”
screening, or fully compliant to “883” MIL-PRF-38534 Class H
screening. Standard microcircuit drawings (SMD) are available.
The MOR Series converters incorporate a single-ended forward
topology which uses a constant frequency Pulse Width Modulator
(PWM) current mode control design and switches at 550 kHz,
nominal.
Short Circuit Protection
The converters also provide short circuit protection by restricting
the current to 125% of the full load output current, typical.
Inhibit Function
All models offer two inhibits, one referenced to input common
and one referenced sense return (single output models) or to
output common (dual output models). A remote sense function is
available on single output models.
Trim Function
Using the trim function, the MOR Series can provide any output
from 2 to 33 VDC. For example, trimming the two 15 volt outputs
of the 15 dual (MOR2815D) to 14 volts, and then stacking the
outputs will provide a 28 volt output.
Output Voltage Options
The MOR Series converters are capable of providing other
output voltage options in addition to those characterized on this
datasheet. Contact your sales representative to discuss other
output voltage options, www.interpoint.com/contacts.
US Patents
Interpoint converters may use one or more of the following US
patents 5,521,807, 5,694,303, and 5,631,822.
