The Victor 883 is a speed controller specifically
engineered for robotic applications. The high current
capacity, low voltage drop, and peak surge capacity make
the Victor 883 ideal for drive systems while its braking
options and precise control meet the demanding needs of
arms and lift systems. This controller safely handles the
high continuous current draws and extreme current surges

Wiring Guidelines
You will need (4) #6 or #8 circle lugs (yellow) for
10AWG wire and (2) #6 or #8 circle lugs (red) for
20AWG wire.
1. The fan must be wired so it is always ON when the
Victor 883 is ON.
2. Attach (2) 20AWG circle lugs to the fan wires and
connect to the Victor 883 input terminals 12V and
GND.
3. The input and output wires should be 10AWG wire
and firmly connected to ensure low voltage drop and
minimal temperature rise.
4. Use circle lugs designed for 10AWG wire. The lug
should have a hole designed for a #6 or #8 screw. If
the center hole is too large, (#10 or larger)
inadequate mechanical contact may result in
excessively high resistance and temperature rise.
5. Check all lug connection after crimping. You should
not be able to pull the lug off the wire with your
hands.

produced by FIRST Competition robots. Innovative FET
switching architecture and an integral cooling fan ensures
cool FET junction temperatures. The low voltage drop
and high switching speed ensures the motor receives
maximum power, providing significant improvements in
acceleration, direction changes, and lifting torque.

6. Once the input and output wires are firmly
connected, tie the wires using tie straps within 2" of
the Victor 883. This will ensure the wires do not
move and loosen the connections.
WARNING: BEFORE APPLYING POWER:
1. Ensure the input connections are not reversed.
Connecting 12V and GND backwards will
destroy the unit.
2. Ensure that there is not a short circuit on the
output. A short circuit will destroy the unit.
3. Ensure there is a 30A circuit breaker inline with
the 12v power input to the speed controller. This
ensures that long term exposure to a stalled
motor will not overheat the Victor 883.
