4. An embedded system equipped with the STUPS is guaranteed to execute proper shutdown sequence every time when power is accidentally or purposely disconnected This significantly simplifies power on off procedures for the system When STUPS is integrated it is acceptable for a user to simply flick the on off switch or unplug the unit if he desires to turn off the system STUPS will handle the shutdown sequence properly in any situation As an option it is possible to apply delay between the moment power level drops below limit and the moment when system starts shutdown This makes allowances for short power glitches without any disruption to the service or operation of the embedded system This feature is beneficial in industrial environments where short power blips are common and low quality of power causes high failure rates of embedded systems Secondary features of STUPS include auxiliary power output 3 3V 5A or 5V 4A system diagnostics voltage current and temperature measurements and system start stop management STUPS can be also used to turn the power to the powered device after a specified time elapsed This can be useful for example in battery powered data acquisition systems that need to perform some measurement in periodic intervals for example once per hour After initial startup the device would perform the measurement task and then send request to STUPS to enter a hibernate state Device would then start it s operating system s

STUPS would switch to backup after awhile the power supply would turn the power on again STUPS would switch back to main input start charger overload the power supply again and the switching back and forth would continue until the STUPS battery gets completely depleted You might not see this problem if the supercap battery is fully charged but could potentially run into this later We strongly recommend to set this parameter to match your particular setup Typically the ampere rating is indicated on the power supply label Occasionally only the maximum output power is provided you can calcuate the rated current by dividing max output power by output voltage e g for 12V 42W supply you calcuate 42 W 12 V 3 5 Amps Setting parameters to desired value The easiest way to set the parameter might be to start the StupsViewCS application connect to STUPS type following command to cmd text box and press Send button servicemode 1 setpar maxinputcurrent 3 5 setpar auxoutputvoltage 5 0 setpar updatemsgfields status runtime battery iout storepars This will change the parameters to specified value and store them into non volatile flash memory This needs to be done once only 16 63 4132 STUPS User Manual Mounting Hole Pattern Mounting Hole Pattern 250 6 35 Dia Pad 125 3 18 Dia Hole Typ 4 places 3 550 90 17 3 350 85 09 3 250 82 55 uo RN A i d R E E amp 3 y 2 350
