DC6 DC Drive Non-Regenerative, 3 Phase Converters DESCRIPTION SAF’s DC6 thyristor converters are intended to power DC motors ranging from 5HP to 1000HP The basic converter unit consists of: a) A 6 thyristor power bridge b) A single control card type A650-L mounted on the power bridge assembly. The entire control circuit is accommodated on this card. c) Synchronizing transformers with mounted power supply relay logic motherboard type A650-MB. This assembly is connected to the control card via a flat ribbon cable and has all START/STOP control function relays. • Automatic resetting of ICT circuit when STANDARD FEATURES operating the normal stop/start circuit • Two quadrant operation (non-regenerative) • Stall protection applications where power will • Impedance isolated armature feedback for cease after a stall period of longer than 12 speed regulation of better than 5% seconds under current limit conditions • Isolated current feedback using current • Adjustable maximum speed with armature transformers feedback • Visual indication of all important control • Adjustable maximum speed with tachometer points within the control card (LED’s) feedback • Single control card for quick replacement • Tachometer feedback loss protection i.e. the • Phase rotation protection with run control will automatically revert to impedance- interlocking and indication isolated armature feedback • Adjustable minimum speed • Jogging facility with independent speed • Adjustable acceleration (1-60 seconds) adjustment • Adjustable deceleration (1-60 seconds) • Two stage current • Adjustable current limit to motor limit feature for • Adjustable IR compensation high initial starting • Adjustable major and minor loop stabilities torque requirements • Protection against instantaneous current overload (ICT circuit) PROTECTIVE FEATURES • Fast acting fuses • Thyristor protection against excessive current overload by means of individual R-C circuitry • Power module over-temperature protection interlocking (above 90ºC) • Instantaneous protection against excessive current overload (ICT) SAF DC6 DC Drive ELECTRICAL SPECIFICATIONS HP RATINGS MAX.

HARD TO FIND A BETTER PROVIDER
Our company provides services to aid in the manufacture of technological products, such as semiconductors and flat panel displays, and often searching for distributors of obsolete product we require can waste time and money. Finding GID Industrial proved to be a great asset to our company, with cost effective solutions and superior knowledge on all of their materials, it’d be hard to find a better provider of obsolete or hard to find products.
Applied Materials
CONSISTENTLY DELIVERS QUALITY SOLUTIONS
Over the years, the equipment used in our company becomes discontinued, but they’re still of great use to us and our customers. Once these products are no longer available through the manufacturer, finding a reliable, quick supplier is a necessity, and luckily for us, GID Industrial has provided the most trustworthy, quality solutions to our obsolete component needs.

TERRIFIC RESOURCE
This company has been a terrific help to us (I work for Trican Well Service) in sourcing the Micron Ram Memory we needed for our Siemens computers. Great service! And great pricing! I know when the product is shipping and when it will arrive, all the way through the ordering process.

GO TO SOURCE
When I can't find an obsolete part, I first call GID and they'll come up with my parts every time. Great customer service and follow up as well. Scott emails me from time to time to touch base and see if we're having trouble finding something.....which is often with our 25 yr old equipment.
