Technical data
4.2 Main power supply
4.2.1 Operational limits in conjunction with a weak power supply
input voltage
In general, the maximum output power of the CMC 310 is limited by the power supply input voltage. If
the power supply input voltage is less than 120 V
AC
, it is possible to supply the CMC 310 with 2 phases
(L-L, for example with a NEMA 6 240 V U.S. Standard) instead of the normal phase-neutral (L-N)
operation in order to increase the power supply input voltage.
In order to limit the internal losses and to maximize the output power of the voltage amplifier, always set
the maximum test object voltage to the minimum value possible for the test.
Apart from the reduction of the available total output power, a weak power supply input does not further
affect the technical data of the
CMC 310 .
