PV- series: Power supply module with UPS and SSD Flash
Page 2 of 8
Description
Micronix PV-5124 is a PC/104 Power Supply with 1.76/3.84 MB Flash SSD which provides a
convenient way to supply both power and solid state disk capacity to PC/104 bus products. The flash
SSD emulates a standard FDD, a complete system can thus be built from just one Micronix PV-5124
and one PC/104 CPU.
By connecting an external battery, an integrated UPS-function will provide a CPU controlled /
automatic shut down procedure of the operating system. An integrated battery charger will insure
maintenance of the battery during operation.
Power Supply
PV-5124 has a high efficiency DC to DC converter with 30 Watt output capability.
The Power Supply will supply +5V, +12V and –12V to the PC/104 bus.
UPS (Uninterruptible Power Supply)
Micronix PV-5124 has an integrated battery charger and built-in UPS function with interrupt alarm
outputs. It also features a CPU controlled / automatic shutdown facility for battery discharge
protection. The automatic shut down procedure is initiated when both “Mains failure” and “Low
battery” have been detected for 120 seconds. At the end of this “shut down time” +5V will be
removed from the system. “Low battery” occurs when Vbat goes below 10.8V. The CPU controlled
shut down is initiated by a user program.
See “Typical discharge/charge cycle” on page 8.
Battery charger
The integrated battery charger will deliver a constant current(400mA) to the battery as long as the
battery voltage hasn’t reached 13.8V. After reaching this point, the charger will act as constant
voltage source(13.5V).
See “Typical discharge/charge cycle” on page 8.
SSD (Solid State Disk)
The SSD can emulate a diskette drive as either drive A or B with up to 3.84 MB of capacity. The
SSD holds factory installed firmware, including a set-up program where you can configure the SSD
during boot, and the diskette data itself.
The SSD is most useful with DOS, where you both can have a complete operating system and an
application on the SSD.
