Command
Description
Sets the Foldback protection to ON or OFF.
FLD 1 (or FOLD ON) - Arms the Foldback protection.
FLD 0 (or FOLD OFF)- Cancels the Foldback protection.
When the Foldback protection has been activated, OUT 1 command will release the
protection and re-arm it, while FLD 0 will cancel the protection.
Returns the Foldback protection status string:
“ON”- Foldback is armed, “OFF”- Foldback is canceled.
Add (nn x 0.1) seconds to the Fold Back Delay. This delay is in addition to the standard
delay. The range of nn is 0 to 255. The value is stored in eprom at AC power down and
recovered at AC power up.
Supply returns the value of the added Fold Back Delay.
Reset the added Fold Back Delay to zero.
Returns the output On/Off status string.
ON- output on. OFF- output off.
Display Voltage and Current data. Data will be returned as a string of ASCII characters. A
comma will separate the different fields. The fields, in order, are: Measured Voltage,
Programmed Voltage, Measured Current, Programmed Current, Over Voltage Set point
and Under Voltage Set Point.
Example: 5.9999, 6.0000, 010.02, 010.00, 7.500, 0.000

OUT?
Sets the OVP level. The OVP setting range is given in Table 7-5. The number of characters
after OVP is up to 12.
The minimum setting level is approx. 105% of the set output voltage, or the value in Table
7-6, whichever is higher. The maximum setting level is shown in Table 5-1. Attempting to
program the OVP below this level will result in execution error response (”E04”). The OVP
setting stays unchanged.
15
OVP n
Returns the power supply operation mode. When the power supply is On (OUT 1) it will
return “CV” or “CC”. When the power supply is OFF (OUT 0) it will return “OFF”.
Returns the Master/Slave setting. Master: n = 1, 2, 3, or 4 Slave: n = 0
Saves present settings. The settings are the same as power-down last settings.
These settings are erased when the supply power is switched off and the new “last settings”
are saved.
Sets Under Voltage Limit. Value of “n” may be equal to PV setting, but returns “E06” if
higher. Refer to Table 7-6 for UVL programming range.
Sets OVP level to the maximum level. Refer to Table 7-5.
Returns the setting “n” where “n” is the exact string in the user’s “UVL n”. When in Local
mode, returns the last setting from the front panel in a 4 digit string.
Returns the setting “n” where “n” is the exact string in the user’s “OVP n”. When in Local
mode, returns the last setting from the front panel in a 4 digit string.
Returns the string auto-restart mode status.
Recalls last settings. Settings are from the last power-down or from the last “SAV”
command.

Sets the auto-restart mode to ON or OFF.
AST 1 (or AST ON)- Auto restart on.
AST 0 (or AST OFF)- Auto restart off.

AST n
Reads the actual output current. Returns 5 digits string.
Example: 200A supply sends 000.50, 110.12, 200.00, etc...
Turns the output to ON or OFF. Recover from Safe-Start, OVP or FLD fault.
OUT 1 (or OUT ON)-Turn On.
