2.6 LOAD CONSIDERATIONS
2.6.1 I NDUCTIVE L OADS
To prevent damage to the power supply from inductive loads, the SFA has
incorporated a overvoltage shutdown circuit on the output. The overvoltage is
preset for approximately 110% of the total rated output voltage. If the output
voltage exceeds this amount for more than a few milliseconds, the output will
shutdown. In order to reset the unit, the input standby switch, will need to be
cycled on and off.
