description
The HR150 Series™ DC/DC converters have been designed to give
industrial applications the same high reliability, small size, and high
performance that Interpoint has provided to military and aerospace
programs since 1969.
models and 250 kHz typical for triple output models. They achieve
high isolation (500 V, 100 megohm) through use of a transformer in
the forward power circuit and an opto-coupler in the feedback control
loop.
HR 150 Series input ranges are 10 to 16 VDC or 18 to 36 VDC.
Outputs are available as 5, 12, 15, ±12, ±15, +5 & ±12, and +5 & ±15
VDC. The converters typically provide greater than 80% efficiency
over the entire input range and from 25% to full load. Line regulation
is typically within 0.1 % and load regulation within 0.2%.
HR150 converters are designed to operate between –40°C and +85°C
case and are short circuit protected up to a case temperature of 85°C.
The combination of high conversion efficiency and heat dissipating
metal enclosures minimizes heat sinking requirements. If additional
dissipation is desired, heat conducting material (PCB, copper sheet,
heat sink, etc.) may be brought into contact with the unit’s baseplate.
An inhibit function is provided for HR150 converters when the inhibit
input pin is connected to the input common. The open circuit voltage
of the inhibit input pin is 8 to 10 VDC (Vin = 12) or 11 to 13 VDC (Vin
= 28). The inhibit input pin must sink approximately 1 mA during the
inhibit state. During inhibit, the converter’s output voltage drops to less
than 1 volt and the input current is typically 8 mA.

eliability
Each HR150 converter is built to perform reliably in the harshest
environments. Assembled using thick-film hybrid technology, HR150
converters have more uniform thermal coefficients and 50% fewer
connections than converters built by surface mount techniques. The
HR150 converter parts use the same manufacturing procedures and
quality controls that we apply to converters designed for commercial
airliners, the space shuttle, advanced fighter aircraft, and other high
reliability applications. The steel cases are hermetically sealed in a dry
nitrogen environment and are guaranteed a maximum leak rate of less
than 10-3 atm-cc/sec. All devices are 100% electrically tested.
