(ET) Controller for sale

["David Roden" <etpost drmm net>]

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.  

Contact me at the address on this page please:

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.
