5.2.12.2 Serial Connection
Two 6240B units serially connected can generate up to 30 V/ï‚±ï€±ï€ A.
The following figure shows a connection diagram in which two units are serially connected using a 4-wire
connection. The SENSE connection is not required for a 2-wire connection.
Figure 5-15 Serial Connection
CAUTION:
1. If the load is short-circuited, the two 6240B units apply reverse polarity voltage to each other. Depending on
the settings, an overload may be generated when a short circuit occurs.
2. Only two units can be connected serially. Do not connect three or more units serially. If the load is short-cir-
cuited, the maximum applicable voltage will be exceeded, and the 6240B may be damaged.
3. When using constant current, the smaller setting current of No.1 and No.2 becomes constant current as in
Figure 5-15. The other one becomes the constant voltage.
6240B No.1
6240B No.2
Output voltage = No. 1 output voltage + No. 2 output voltage (for constant voltage)
Output current = The smaller setting currents of No.1 and No.2 (for constant current)
