Appendix 5  Two-Unit Parallel Connection

When two units are connected in parallel to the large current terminals of the 2560A, up to 73.44 A of 
DC current can be output to the two units.

 

Output target device

LO

HI

Note

The specifications of accuracy, stability, and temperature coefficient are those obtained by adding the values 
for two units.
