All of 4QD’s controllers can have some optional extras;
Water resistant coating
This is a high performance acrylic coating which is applied by hand after we have tested and assembled your controller. It doesn’t mean you can take it swimming, but it does make the controller a lot more resistant to splashes and high levels of humidity. We recommend this option if you are fitting to a boat, or to a golf cart due to the spray from the wheels on wet grass.
Spare IDC pack
The controller comes with a set of IDC plugs to connect to all the sockets. These are a one time crimp fit onto the wires and are crimped by using a pair of parallel jaw pliers. It can be useful to have spare connectors in case more than one fitting is needed.
The contents depend on the model of controller as follows;
Porter = 2 x IDC-005
DNO = 2 x IDC-006, 1 x IDC-003, 1 x IDC-004
Pro-150 = 2 x IDC-006, 1 x IDC-003
4QD-200 / 300 = 2 x IDC-006, 1 x IDC-003, 2 x IDC-004
48V optimisation; although the 4QD-200 / 300 will run on 24V or 48V, there are some modifications that we can do at production to optimise performance at 48V.
