8.12 Current Sink Option (-SNK)
The –SNK or current sink option enables the MX/RS power source to sink current from the
unit under test. This mode of operation is particularly useful when testing grid-tied products
that feed energy back onto the grid. The ability of the MX/RS to simulate the grid provides
unique opportunities to test the EUT for immunity to commonly occurring line anomalies like
voltage and/or frequency fluctuations. Typical examples of these types of EUT’s are solar
and/or wind power inverters.
For more details on the regenerative mode of operation, refer to the MX Series User Manual
P/N 7003-960 or RS Series P/N M440036.
The following REGenerate subsystem SCPI commands may be used to control the
regenerative mode of operation if the –SNK option is installed:
Subsystem Syntax
REGenerate:
CURRent Sets the rms regenerate current limit.
DELay:
FREQueny:
[SHUTdown] Delay till frequency deviation, 0.25 to 10
sec.
OUTPut:
[SHUTdown] Delay till output off, 0.25 to 10sec.
DEViate:
FREQueny: 0 to 5 Hz
[:STATe] ON|OFF Turns SNK mode ON or OFF.
OVER:
[VOLTage] accept over voltage range limit
UNDer:
[VOLTage] accept under voltage range limit
REGenerate:CURRent
This command will set or query the regenerate current limit over which the EUT is allowed to
operate. Note that this current limit set point is different from the normal mode current limit
setting.
Command Syntax REGenerate:CURRent
Parameters 0 to max. value for selected current range.
Unit A (rms amperes)
Examples REG:CURR 12
Query Syntax REGenerate:CURRent?
