parallel to increase the current: I
MAX (one unit)
x N
P
= I
MAX (parallel combination)
where N
P
= number
of units in parallel. Similarly, up to two units (including the master) can be connected in series to
increase the voltage: E
MAX (one unit)
x N
2
= E
MAX (Series combination)
where N
2
= number of units in
series.
2.8.1 SERIES CONNECTIONS
Two identical KLN 750W units can be operated in series to double the output voltage.
CAUTION: TOTAL VOLTAGE MUST NOT EXCEED 600V TO AVOID DAMAGING THE
UNITS.
See Figure 2-10 for series connections without local sensing and Figure 2-11 for series connec-
tions with remote sensing. See PAR. 3.4.1 for operating units connected in series.

2.8.1.1 SERIES CONNECTIONS USING OPTIONAL SERIES CONNECTION KIT
Connections for two identical KLN 750W units operated in series to double the output voltage
can be simplified by using the optional Series ConnectIon Kit (see Table 1-4).
CAUTION: TOTAL VOLTAGE MUST NOT EXCEED 600V TO AVOID DAMAGING THE
UNITS.
NOTE:
Adding local sensing wires
from + to +S and from – to –S
on both the Master and Slave
will make the front panel volt-
age reading slightly more
accurate (~10mV).
