c) Specification
Note :
* Droop is based on a speed sensor frequency of 4,000 Hz and an actuator current.
Change of 1 amp from no load to full load. Applications with higher speed sensor signals will
experience less percentage of droop. Applications with more actuator current change will
experience higher percentages of droop. See droop description for specific details on
operation of droop ranges.
** Protected against reverse voltage by a series diode. A 15 Amp. fuse must be Installed in the
positive battery lead.
*** Protected against short circuit to actuator (shuts off current to actuator), unit automatically
turns back on when shorts is removed.
