MODEL-9612-01
This DC-Drive ranges from 0.25H.P. to 1.0H.P. It has a input of single phase 240V AC; 50Hz. We can have stable, regulated output from 0 to 180V DC through a potential free ON/OFF contact and a 4K7 pot. It can give stable output from180V AC to 270V AC as input. It has all the features of any modern type dc-drive like current limit; soft start; IR Compensation; maximum and minimum o/p latch and fuse protection.





MODEL-09Q11
This DC-Drive ranges from 0.5 to 3.0H.P. It has all the features of model 9612-011 in addition it has a solid state field failure protection, which can be used for series wound, laminated yoke and shunt type motors, where as for permanent magnet motors it can be by-passed. Single card version. Size is 225X235X90mm.




MODEL-07Q11
This is a presision type trouble free tough drive used for heavy-duty hours. Has all the features of model-09Q11 plus it has isolated voltage and current feedbacks, and its two cards and a choke for extra protection is mounted on a backallite of approximate size 320X425mm, with a height of 100mm.



MODEL-10Q1X
This has all the features of model-07Q11 leaving choke and is in the form of double- deckker, lower part is power section and upper is control.
It is different from model-07Q11 as it does not have a field failure protection but can be provided optionally if demanded, also it can operate on single as well as two phase supply but this has to be mentioned at the time of ordering.





MODEL-11Q42
It is a four-quadrant drive used for applications where instant stopping is required.
It finds application in lifts, CNC and SPM. It takes input from a 2-phase supply through a centre tap transformer and gives a output from -180V DC to +180V DC, through a pot.

MODEL-12Q13
It is a single quadrant; three phase dc-drive used for higher ratings ie 5.0H.P. to 60.0H.P. It has features like field failure protection; single phasing / phase fail protection; current limit; soft start; soft end; IR Compensation; over temperature trip; minimum and maximum output latch & 6 pulse synchronising.ln this drive output can be set from 0 to 380/440V DC as desired.
