(ET) Controller for sale
I have a barely-used 300 amp, 36 volt 4QD controller for sale.
The big advantage this has over a Curtis is that it can be configured for
true 2 quadrant (joystick or wig-wag) operation. That is, center of the
speed control is off, pull back for reverse, push forward for forward.
All
handled electronically with no relays.
Configuring wig-wag requires only moving a jumper on the logic board.
Factory default is conventional potbox control with a reversing switch.
This controller was designed for permanent magnet motors as used in some
smaller and later ETs. However it can be used with a wound field motor if
you provide a separate means to energize the field.
Potbox not included. It uses a 5-10k ohm true (3-terminal) potentiometer.
I can send manual PDF and/or photos off list.

Priced lower than a a cheap Chinese Curtis knockoff, $120 plus shipping.
Or make me an offer. It has to be out of here before Christmas.
