8.7.5. Output Control Commands
# Command Description
1 PV n
Sets the Output voltage value in Volts. The range of voltage value is described in Table 8-
6. The maximum number of characters is 12. See the following examples for PV n format:
PV 12, PV 012, PV 12.0, PV 012.00, etc…
2 PV?
Reads the Output voltage setting. Returns the string “n” where “n” is the exact string sent
in the PV n command. When in Local mode, returns the PREVIEW (front panel) settings
in a 5 digit string.
3 MV?
Reads the actual Output voltage. Returns a 5 digit string.
Example: 60V supply sends 01.150, 15.012, 50.000, etc…
4 PC n
Set the Output current value in Amperes. The range of current values is described in
Tables 8-7 and 8-10. The maximum number of characters is 12. See the following
examples for “PC n” format PC 10, PC 10.0, PC 010.00, etc…See Note 1
5 PC?
Reads the Output current setting. Returns the string “n” where “n” is the exact string sent
in the “PC n” command. When in Local mode, returns the PREVIEW (front panel) settings
in a 5 digit string.
6 MC?
Reads the actual Output current. Returns a 5 digit string.
Example: 200A supply sends 000.50, 110.12, 200.00, etc…See Note 2
7 DVC?
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
8 STT? Reads the complete power supply status.
Returns ASCII characters representing the following data, separated by commas:
MV: <actual (measured) voltage> PC: <programmed (set) current>
PV: <programmed (set) voltage> SR: <status register, 2-digit hex>
MC: <actual (measured) current> FR: <fault register, 2-digit hex>
Example response: MV(45.201),PV(45), MC(4.3257), PC(10), SR(30), FR(00)
9 FILTER nn
Set the low pass filter frequency of the A to D Converter for Voltage and Current
Measurement where nn = 18, 23 or 46Hz (default is 18Hz)
10 FILTER? Returns the A to D Converter filter frequency: 18,23 or 46 Hz (default is 18Hz)
11 OUT n
Turns the Output to ON or OFF. Recover from Safe-Start, OVP or FLD fault.
“OUT 1” (or “OUT ON”): Turn On.
“OUT 0” (or “OUT OFF”): Turn Off
12 OUT?
Returns the Output On/Off status string.
ON - Output On. OFF - Output Off.
13 FLD n
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, the “OUT 1” command will release the
protection and re-arm it, while “FLD 0” will cancel the protection.
14 FLD?
Returns the Foldback protection status string:
“ON”: Foldback is armed. “OFF”: Foldback is cancelled.
15 FBD nn
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 memory at AC power down and
recovered at AC power up.
16 FBD ?
Supply returns the value of the added Fold Back Delay.
17 FBDRST
Reset the added Foldback Delay to zero.
18 OVP n
Sets the OVP level. The OVP setting range is given in Tables 8-8 and 8-11. The number
of characters after OVP is up to 12. The minimum setting level is approximately 105% of
the Output Voltage setting, or the values in Tables 8-8 and 8-11, whichever is higher. The
maximum OVP setting level are shown in Tables 8-8 and 8-11. Attempting to program the
OVP below this level will result in an execution error response (“E04”) and the OVP
setting stays unchanged.
19 OVP?
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.
20 OVM
Sets the OVP level to the maximum level. Refer to Tables 8-8 and 8-11.
21 UVL n
Sets the Under Voltage Limit. Value of “n” may be equal to PV setting, but returns “E06” if
higher. Refer to Tables 8-9 and 8-12 for the UVL programming range.
