002 - 3.2 Multiple DC1000S in Parallel
You can generate up to 250A as a maximum by connecting up to ten DC1000s together in parallel. Either the first DC1000, or a PC or a Voltech AT3600 or ATi can be used to control all the other DC1000s in the chain – automatically adjusting their output current to allow you to easily achieve the results you require.
Everything you need to hookup multiple DC1000s is provided with the units themselves. Fig.5 illustrates the connections required.
Be sure to connect the HI side of your LCR meter to the same side of the inductor to which the HI sides of your DC1000s are attached, and use the opposite side of the inductor to connect the LO sides of both the DC1000s and the LCR meter.
Connect the 9-Way RS232 cable between the RS232 OUT of the first DC1000 in your chain and the RS232 IN of the second DC1000, using the cable provided with your DC1000. Then, if you have more than two DC1000's, connect the RS232 OUT of the second DC1000 in your chain to the RS232 IN of the third. Follow the same pattern for any remaining DC1000's you wish to connect together in parallel.
Always connect directly from EACH DC1000 in your chain to the inductor. NEVER daisy chain the outputs of multiple DC1000's. The accumulated current could exceed the rating for the supplied cable, and cause fire and injury.
LCR COMPENSATION WITH MULTIPLE DC1000S
When compensating your LCR meter for use with the DC1000s, always set each DC1000's current to '0.00' and turn the output ON at each unit.
