7.7.5 Output Control Commands
Sets the output voltage value in Volts. The range of voltage value is described in Table 7-3. 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…
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.
Reads the actual output voltage. Returns a 5 digits string.
Example: 60V supply sends 01.150, 15.012, 50.000, etc…
Sets the Output Current value in Amperes. The range of current values is described in Table 7-4
and 7-5. The maximum number of characters is 12. Examples for PC n format: PC 10, PC 10.0,
PC 010.00, etc…See Note 1
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.
Reads the actual Output Current. Returns a 5 digit string.
Example: 200A supply sends 000.50, 110.12, 200.00, etc…See Note 2
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 O), it will return “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
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)
Set the low pass filter frequency of the A to D Converter for Voltage and Current Measurement
where nn = 18, 23 or 46 Hz (default is 18)
Returns the A to D Converter filter frequency: 18,23 or 46 Hz.
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
Returns the output On/Off status string.
ON - output On. OFF - output Off.
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 cancelled.
Add (nn x 0.1) seconds to the Fold Back Delay. This delay is in addition to the standard 250 mSec
delay. The range of nn is 0 to 255 (0 to 25.5 Sec). The value is non-volatile until the “FDBRST”
(fold back reset) is sent.
Supply returns the value of the added Fold Back Delay.
Reset the added Fold Back Delay to zero. Restore the standard 250mSec delay.
Sets the OVP level. The OVP setting range is given in Table 7-6. The number of characters after
OVP is up to 12. The minimum setting level is approximately 105% of the Output Voltage setting,
or the value in Table 7-6, whichever is higher. The maximum OVP setting level is shown in Table
5-1. Attempting to program the OVP below this level will result in an execution error response
(“E04”). The OVP setting stays unchanged.
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.
Sets OVP level to the maximum level. Refer to Table 7-6.
Sets Under Voltage Limit. Value of “n” may be equal to PV setting, but returns “E06” if higher.
Refer to Table 7-7 for UVL programming range.
