Victor 883
An older speed controller used in FIRST robotics competitions from 1999 to 2003. This speed controller is not allowed in competition any more and has been replaced by the Victor 884, which has a greater degree of control and a higher current limit. It replaced the Tekin REBEL.

Q: How many Victor 883’s can we connect to one PWM output? A: You can safely connect two speed controllers to one output. Each requires about 7mA of current for the opto-coupler. The drivers supply 25mA. Three is pushing it. Also you only want to connect the same type (Red vs. Blue) on the same output. They have different input circuitry. Finally, you do not want a servo and a either type of Victor to share the same output. The opto circuit on the Victor reduces the voltage level of the PWM signal too low for the servo to work reliably.
