Thomson Power Systems Quick Conect Panel

Thomson Power Systems - QCP - Allows for a quick connection from a transfer switch to an onsite, portable generator


Having a solution to quickly and safely make a portable generator connection to your electrical distribution system is important and in some cases required. When normal power is interrupted during a natural disaster, or main utility power failure, the Quick Connection Panel (QCP) and Transfer Switch Connection Plate (TCP) enables your facility to accept temporary service from a rental or portable generator. 

Connecting portable generators can pose serious risks if not done properly. The Thomson Quick Connection Panel (QCP) and Transfer Switch Connection Plate (TCP) are certified to the UL 1008 standards for safe and easy connections to Automatic Transfer Switches.

On-Site Power, Inc. has been an avid supporter of Thomson Technology Power Systems.

Their ATS's were serviceable. You could trouble shoot down to the smallest part. That made it the least throw away ATS in the market.

 The TSC80e was bullet proof. Short of taking a lightning hit, they seemed to be the most robust ATS control.

To keep up with the times TTI came out with the 900 series control. They were so proud of it that they made the TSC80e obsolete. The 900 has touch screen & is impressive. The problem is we had a bunch of failures here in Florida.. First the SIM cards had to be replaced. Then we had to update the software in the controls on multiple occasions to fix glitches. But worst of all, the heat got to them. The screens got hard & cracked, then you could not see what you were touching any more, Then the screen would go blank!

TTI wants the owner to replace the TSC80e with what they call an upgrade to the 900 series.

The TS series ATS’s are still operable, serviceable & they would continue to be ‘if’ an owner could get a TSC80e.


OSP has started a remanufacture program. We are sending our cores to be rebuilt. Why throw a perfectly good ATS away because you cannot get the TSC80e & don’t want the 900 series ‘upgrade’.  Before they discontinued the TSC80e their MSRP was $1,750.00. Now you cannot get it.  A 900 series control & touch screen is over $ 3,500.00 plus freight.


Now you can buy a remanufactured TSC80e that is a direct replacement, in stock in Ocala. Electronic components usually do not carry a warranty, but we extend one year warranty on workmanship and components. 

 Right now, you can buy a remanufactures TSC80e board. There is a core charge to get the old one back.    Otherwise, the program would run dry of cores. No additional freight. No surprise fees or extras.

As a follow-up to our 01/01/21 announcement of the reman TSC80eR we would like to provide another offer.

                The TSC80eR is still available as a solution to not have to upgrade to the 900 control.

The next challenge was to figure out how to replace the 900 control as they failed.

                We began to replace the TSC 900 series control with a Deep Sea controller, but there was a lot of work to make it work. It was certainly not a direct replacement & was not a plug & play.

                It would be a challenge if someone calling in wanting to buy parts because it is difficult to describe the fab work involved.

                The TSC900 series control is made up of an SCU, the switch control unit, GHC, the graphic human control ( touch screen) & SD Cards ( software programming). These can be purchased to keep the 900 series control. But we wanted to find a way to offer an option:

                The solution is: Part Number: P-334-TS870.

This is a TSC900 series replacement kit. It is a plug & play.  It is a direct replacement & costs less than buying the 900 series controls. They are built-to-order if lead time is a concern. At this time there is no literature on them yet.

If lead time or literature is a concern, we are still competitive on an SCU, GHC and/or SD Cards; but you will still have 900 series control.
