SET-UP: See section "G" for engineering and installation notes.
CURRENT LIMIT ADJUSTMENTS:
These amplifiers feature peak and continuous current limit adjustments. DIP switches reduce both peak and continuous
current limit. The ratio of peak/continuous current limit is fixed (50%). The switches also adjust the scaling of CURR-
MONITOR output.

The actual current can be monitored at pin P1-15 and is referenced to POWER GND P2-4.
OPTICAL INPUT SIGNAL ISOLATION:
PWM, DIR, INH, FAULT inputs are always isolated from the power section. If the isolation option is selected the Hall
sensor inputs (P1-10 through 14) are also isolated. If the isolated version is not ordered, an isolated power supply should
be used with this series of amplifiers.
ORDERING INFORMATION:
Models: BD30A8X, BD25A20X
With isolation:
Models: BD30A8IX, BD25A20IX
