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.
