Chapter 1 I NTRODUCTION
This user’s manual describes the operation of the IPWR104HR high power density
galvanically isolated power supply unit for automotive and industrial applications.
Features
Some of the key features of the IPWR104HR include:
•Wide input voltage range 18-36V DC or 36 to 75V DC
•60W / 100W output power guaranteed with adequate cooling, 88% efficiency
•Remote ON/OFF operation (at request)
•Power output options include: +5V, +12V, -12V, -5V
•Three status LED's
•Standard floppy power output connector (J12)
•DC/DC converter conforms to UL1950 , EN60950 and CSA22.2 #234
• Extended operating temperature (-40 to +85 C) available in IDAN enclosures
The following paragraphs briefly describe the major features of the IPWR104HR. A
more detailed discussion is included in Chapter 3 (Hardware description) The board
installation is described in Chapter 2 (Board Installation).
Power supply units
The IPWR104HR isolated power supply unit offers a complete reliable power
subsystem for your sophisticated computer and peripherals. To improve reliability
in noisy environments, the IPWR104HR is designed using an isolated power
supply module for the computer and the peripheral system components. This
enables reliable system operation in distributed industrial installations.
The main +5V computer power supply is designed using a monolithic switching
regulator module providing high output current (20A) with a high efficiency (88%).
The secondary peripheral power supplies are designed using +12V and -12V
converters. -5V is an 100mA LDO cascaded off the -12V converter.
The IPWR104HR can be “switched off” from a remote source. If this switch (X1
jumper) is opened the power supply will become inactive while still powered.

Board options
The IPWR104HR is available in two main output configurations as set out below:
Option 1 IPWR104HR-H +5V, +12V, -12V, -5V outputs, 33-75V input range
Option 2 IPWR104HR-L +5V, +12V, -12V, -5V outputs, 18-36V input range
Mechanical description
The IPWR104HR is designed on a PC/104 form factor. An easy mechanical
interface to both PC/104 and EUROCARD systems can be achieved. Stack your
IPWR104HR directly on a PC/104 compatible computer using the onboard
mounting holes. Care must be taken to ensure adequate heat dissipation from the
onboard heat sink in high output power installations. (RTD can offer heat sinks for
the DC/DC converter).
Connector description
The power connections can be made with "cable plug" type terminal blocks. This
enables removing connections from the board without opening the cables from the
terminal blocks. A 4-pole "floppy type" connector is also available for easy wiring to
PC peripherals.
