Output programming

Voltage and current

The output voltage and output current are controlled by the VOLTage and CURRent commands. The output ON/OFF state is controlled by the OUTPut command.

:VOLTage 13.5    'Set the voltage to 13.5 V

:CURRent 4.5    'Set the current to 4.5 A

:OUTPut ON    'Turn the output on

To set the preset current to the maximum value, set the value of the CURRent command to MAXimum.

The current setting limit is set to approximately 95 % of the value specified by the CURRent:PROTection command if the CURRent:LIMit:AUTO command is set to ON (1). The setting limit cannot be set above this value. If the CURRent:LIMit:AUTO command is set to OFF (0), the setting limit is the maximum value of preset range (105 % of the rated output current).

:VOLTage 13.5    'Set the voltage to 13.5 V

:CURRent MAXimum    'Set the current to the max.value

To set the preset voltage to the maximum value, set the value of the VOLTage command to MAXimum.

The voltage limit setting is set to approximately 95 % of the value specified by the VOLTage:PROTection command if the VOLTage:LIMit:AUTO command is set to ON (1). The setting limit cannot be set above this value. If the VOLTage:LIMit:AUTO command is set to OFF (0), the setting limit is the maximum value of preset range (105 % of the rated output voltage).

:CURRent 4.5    'Set the current to 4.5 A

:VOLTage MAXimum    'Set the voltage to the max.value

You can confirm the maximum allowed value that can be specified in the VOLTage and CURRent commands by specifying the MAXimum parameter in the VOLTage? and CURRent? queries, respectively.

:VOLTage? MAXimum

<Read the response>

:CURRent? MAXimum

<Read the response>

The values that the queries above return may vary depending on the VOLTage:PROTection (OVP) and CURRent:PROTection (OCP) settings.

If a value exceeding the upper limit is specified with the VOLTage or CURRent command, it is interpreted as MAXimum and does not result in an error.

Setting the protection functions

The PAT-T provides overvoltage protection (OVP) and overcurrent (OCP) functions that can be configured. The VOLTage:PROTection and CURRent:PROTection commands are used to set the OVP and OCP, respectively.

:VOLTage:PROTection 16.0    'Set the OVP to 16 V

:CURRent:PROTection 7.5    'Set the OCP to 7.5 A

If you want to set the OVP or OCP setting to the maximum or minimum value, you can specify MAXimum or MINimum for the parameter.

:VOLTage:PROTection MAXimum    'Set the OVP to the max value

:CURRent:PROTection MAXimum    'Set the OCP to the max value

The output turns off if an OVP or OCP activates. Whether the breaker is to be tripped at this point can be specified using the SYSTem:CONFigure:BTRip:PROTection command.

SYSTem:CONFigure:BTRip:PROTection ON    

    'Setting in which the breaker is tripped when the OVP or OCP activates
