KLN Series 051614
B.14 SOURce:CURRent COMMAND
SOUR:CURR
Syntax: Short Form: SOUR:CURR <NRf> Long Form: SOURce:CURRent <NRf>
Description: Sets the output current value. Maximum output current is rated current; minimum current is
zero.
Argument: <NRf> is a value in the range from 0 to rated current of unit. Rated voltage and current are defined
by model (e.g., for KLN 6-100, rated voltage is 6V, rated current is 100A).
Example: SOURce:CURRent 25 sets output current value to 25A.
B.15 SOURce:CURRent? QUERY
SOUR:CURR?
Syntax: Short Form: SOUR:CURR? Long Form: SOURce:CURRent?
Description: Indicates programmed output current (in amperes).
Return Format: <NRf>
Example: SOURce:CURRent? returns 2.50000E+01 to indicate output current is programmed to 25A.
B.16 SOURce:CURRent:PROTection:LEVel COMMAND
SOUR:CURR:PROT:LEV
Syntax: Short Form: SOUR:VOLT:PROT:LEV <NRf>
Long Form: SOURce:CURRent:PROTection:LEVel <NRf>
Argument: <NRf> is a value in the range from 10% to 110% of rated current.
MIN is the value programmed for output current (SOUR:CURR)
MAX is 110% of rated current of unit
Description: Sets the overcurrent protection (OCP) value (in amperes). OCP values set using this com-
mand are in effect once the unit is returned to local operation. Maximum value is 110% of rated
voltage. MIN sets OCP to be the same as the value programmed for output current. *RST sets
SOUR:CURR:PROT:LEV to maximum value.
Example: SOURce:CURRent:PROtection:LEVel 27.5 sets the overcurrent protection level to 27.5A. This is
the maximum value if the unit is a 30V, 25A model. SOUR:CURR:PROT:LEV MIN sets the over-
current protection level to be the same as the programmed value of output current (SOUR:CURR).
B.17 SOURce:CURRent:PROTection:LEVel? QUERY
SOUR:CURR:PROT:LEV?
Syntax: Short Form: SOUR:CURR:PROT:LEV? Long Form: SOURce:CURRent:PROtection:LEVel?
Description: Indicates programmed overcurrent protection (OCP) level for output current (in amperes).
Return Format: <NRf>
Example: SOURce:CURRent:PROtection:LEVel? returns 2.75000E+01 to indicate overcurrent protection
level is programmed to 27.5A.
B.18 SOURce:CURRent:PROTection:STATe COMMAND
SOUR:CURR:PROT:STAT
Syntax: Short Form: SOUR:VOLT:PROT:STAT <bool> {ON | OFF}
Long Form: SOURce:CURRent:PROTection:STATe <bool> {ON | OFF}
Argument: 1 or ON enables the foldback circuit for current protection
0 or OFF disables the foldback circuit for current protection
Description: Controls whether the output Current Protection (OCP) foldback protection circuit is
enabled. The foldback protection circuit turns the output off if the power supply is operating in con-
stant current mode and current exceeds the programmed value of SOUR:CURR:PROT:LEV for
0.5 Second.
Example: SOUR:CURR:PROT:STAT 1 enables the foldback current protection
B.19 SOURce:CURRent:PROTection:STATe? QUERY
SOUR:CURR:PROT:STAT?
Syntax: Short Form: SOUR:CURR:PROT:STAT? Long Form: SOURce:CURRent:PROtection:STATe?
Description: Indicates state of overcurrent protection (OCP)
Return Format: <bool> 1 = enabled, 0 = disabled
Example: SOUR:CURR:PROT:LEV? returns 0 to indicate OCP protection is disabled.
