ENTRY DESCRIPTION
V OLT M ODE Selects the available output modes of operation. A vailable modes are AC, DC (all
models) and A CDC (Pi models only). The shuttle can be used to select the desired
output mode.
DC OFFSET This parameter applies only when the power source is in A CDC mode. The DC offset
can only be set to a max value of 220V DC. The rms level of the A C+DC waveform
may not exceed the limit of the voltage range (150V or 300V ).
Note: Changing the offset percentage setting will result in temporary loss of the
output voltage as the new offset is loaded. This may cause the EUT to reset or turn
off. To avoid this, set the desired offset percentage before programming the AC
voltage and turning on the output to the EUT.
CURR Sets the current limit value for the current detection system. W hen the load current
value exceeds the set current limit, a fault condition is generated. The actual
response of the A C Source to a current limit fault is determined by the protection
mode selected in the OL M ODE field. (CC = Constant Current, CV = Constant
V oltage).
OL M ODE Sets the current limit overload mode. The actual response of the A C Source to a
current limit fault is determined by this setting. A vailable settings are CC for
Constant Current mode or CV for Constant V oltage mode. In CV mode, the A C source
output will trip off and stay off until re-engaged. In CC mode, the voltage will be
reduced until the current limit is no longer exceeded.
