4.12.2 Serial Connection
Using two 6243/44 units in series enables use of a source up to 220 V/0.5 A (6243) or 40 V/4 A
(6244).
Figure 4-24 shows a connection diagram in which two units are serially connected using a 4-wire connec-
tion. The SENSE connection is not required for a 2-wire connection.

NOTE:
1. If the load is short--circuited, reverse polarity voltage is applied to the 6243/44 themselves. Depending on the
settings, overload or reverse source may be generated when short-circuit occurs.
2. Two units can be connected serially. Do not connect 3 or more units serially.
If the load is short-circuited, the maximum applicable voltage will be exceeded, and the 6243/44 may be dam-
aged.
3. When using constant current, the current setting value becomes the smaller of the two current settings as
shown in Figure 4-24. The other becomes the constant voltage.
4. When serially connecting a 6243 and a 6244, set each of them to 20 V or lower.
