RTD VPWR104HR Embedded PC/104 Power supply module Simple Type: Power Supply

The VPWR104HR power supply unit offers a complete reliable power subsystem for your sophisticated computer and peripherals. To improve reliability in noisy environments, the VPWR104HR is designed using protection devices against over voltages, noise spikes and reverse input voltage. The output current of the +5V converter is limited to 10A. These features allow reliable system operation in distributed industrial installations. The +5V computer power supply is designed using a high efficiency switching regulator providing high output current (10A) with efficiency as high as (90 %) under all conditions. The secondary peripheral power supplies are designed using +12V and -12V converters that are supplied by the +5V DC/DC converter. Low component count and extensive use of SMD technology ensures low weight and reliable operation. Special care has been taken to reduce radiated and conducted emissions. Optimized multi-phase circuit layout ensures good EMI immunity over the operating temperature range under all loads. The VPWR104HR can be “switched off” from a remote source. If this switch (jumper) is closed the power supply will become inactive while still powered. The VPWR104HR is designed on a PC/104 form factor. An easy mechanical interface to both PC/104 and EBX systems can be achieved. Stack your VPWR104HR directly on a PC/104 compliant computer using the onboard mounting holes. Care must be taken to ensure adequate heat dissipation from the board in high output power installations. The power connections are made using "cable plug" type terminal blocks. This enables removing connections from the board withoutopening the cables from the terminal blocks. The IDAN-VPWR104HR boards always feature screw terminal blocks for inter- frame wiring.
