BIDIR-115D Datasheet, PDF (6/6 Pages) List of Unclassifed Manufacturers – 15 Amp Bidirectional Digital PWM Motor Speed Controller

BIDIR-115D(S) Speed Controller
Application Notes:
The controller automatically puts the motor into braking mode when power is removed. Please be
aware that if the motor is still spinning when the power is removed, the motor will brake
suddenly.
PWM controllers switch currents at high frequencies to vary the average power to the load. This
switching can cause undesirable RF interference. To minimize such interference, it is
recommended to twist the input V+ and Ground wire pair as well as the Out+ and Out- wire pair.
In addition, installation of a small capacitor from each of the two motor terminals to the metal
case may reduce noise emission.
A fuse appropriately rated for the load device can help enhance safety.
This controller is not reverse-polarity protected. Ensure that it is wired correctly before applying
power. Always turn off the power supply before making any changes to the wiring.
Ensure that the controller has adequate air flow for proper cooling. If operating for extended
periods of time in high temperature environments, a cooling fan may be necessary.
Use the shortest possible wires between the motor and controller, and between the controller
and the power source. Ensure that the wires carrying the load current are adequately sized. If
operating heavy inductive loads, it may be advisable to add an appropriately rated filter capacitor
at the input to the PWM controller. Inadequate power supply filtering or other causes leading to a
high impedance path to the power supply will result in higher losses in the filter capacitor and
wiring, reducing overall system efficiency.
