Parallel Connection
Using two 6243/44 units in parallel connection enables use of a source up to
4 A/
32 V (6243) or
20 A/
7 V (6244).
Figure 4-25 shows a connection diagram in which two units are connected in parallel using a 4-wire con-
nection. Two units are used for voltage measurement when measuring voltage at two points such as for
pulse charge and discharge test of batteries.

NOTE:
1.
If the load is opened, current flows from the higher to the lower of the set voltages.
Depending on the settings, overload and reverse source may be generated.
2.
If the load is opened when 3 or more units are connected in parallel, the one to be used as source and the one
to be use as sink are decided by the set voltage, and voltage control is performed in accordance with this bal-
ance.
