The power supply can accept values higher by 5% than
the table values, however it is not recommended to
program the power supply over the rated values.

7.7.6 Global output commands
1. General
All supplies, even if not the currently addressed supply, receivingaglobal command will execute
the command. No response to the PC issuing the command will be returned to the PC. The PC
issuing the command will be responsible to delay and any other communications until the
command is execute. 200 Ms minimum is the suggested delay.
If the command contains an error, out of range values for example, no error report will be sent to
the issuing PC.
Reset. Brings the Power Supply toasafe and known state:
Output voltage: 0V, output current: 0A, OUT:Off, Remote: RMT 1’
AST:Off OVP:Max, UVL:0.
The conditional register (FLT and STAT) are updated. Other registers are not changed.
Non-Latching faults (FB, OVP, SO) are cleared, OUT fault stays.
Sets the output voltage value in volts. The range of voltage values is shown in Table 7-3.
‘n’ may be up to 12 char plus dec. pt
Program the output current value in amperes. The range of current values is shown in
Table 7-4. ‘n’ may be up to 12 char plus dec. pt
Turns the output to ON or OFF:
“GOUT 1/ON”=turn on
“GOUT 0/OFF”= turn off, clears CV and CC bitsin the Status Condition (STAT)
OUT ON will respond with “E07’if the output cannot be turned on because ofalatching
fault (OTP< AC, ENA, SO) shutdown.

Saves to the RAM. These settings are erased when the supply power is switched off and
the new ‘last settings’ are saved.
5.
GSAV
Recall last settings. Settings are from last power-down or from last ‘SAV’ or ‘GSAV’
command. Address and Baud rate are not recalled so communication is not interruped.

NOTES:
1. In Advanced parallel mode (refer to Sec. 5.15.2), “n” is the total system current.
2. In Advanced parallel mode, “MC?” returns the Master unit current multiplied by the number of
slave units+1.
