PWM OUTPUTS (PWM OUT) – Qty (3)
These outputs are designed to proportionally sink current to ground using Pulse Width
Modulation (PWM). Each output can be configured for a specified current range. This
allows for maximum current sensing resolution for each application. All outputs are
short circuit protected and current ranges above 150mA have open and short circuit
detection as well.
Current Ranges – Each PWM output can be configured to a current range, which will
produce the maximum current sensing resolution (see ordering guide).
Note: Current ranges “L”, “H”, and “D” are short circuit protected but do not have short
circuit detection.
OUTPUT GROUPS (3)
The outputs are divided up into 3 output groups. Each output group has (2) High-Side
outputs and (1) PWM output.

features.
INPUT/OUTPUT FUNCTIONS – Qty (6)
The DVC750 Firmware incorporates six separate Input / Output Functions that can be
individually programmed. The I/O Function gives the user the ability to change the
relationship of the output with the input (see sample screen below). This gives the user
the ability to program a linear response on the output in relation to a non-linear input
curve on the input or visa-versa. The input and output being controlled must both reside
on the DVC750. The input and output is based on 0 to 100% (Min. to Max.). Different
