Protection
Five configurable protection mechanisms are available:
•
OVP:
Over-Voltage Protection. Factory default = 0V (disabled)
•
UVP:
Under-Voltage Protection. Factory default = 0V (disabled)
•
OCP:
Over-Current Protection. Factory default = 0A (disabled)
•
UCP:
Under-Current Protection. Factory default = 0W (disabled)
•
Fold:
Fold Protection. (See below.)
OVP shuts down the power supply if the protection limit is exceeded. The other
options offer a choice: they shut down the power supply or issue a warning by setting
a bit in the status register. Set the protection mechanism to ON to enable it to
shutdown the power supply.
When the protection level is set to zero, that mechanism is disabled. However, in the
case of OVP, a fixed hardware protection mechanism still exists to protect the supply
from damage.
To set the over-voltage protection level:
SOUR:VOLT:PROT <voltage>
To set the under-voltage protection level:
SOUR:VOLT:PROT:UND <voltage>
To enable UVP shutdown:
SOUR:VOLT:PROT:UND:STAT <on-off-state>
To set the over-current protection level:
SOUR:CURR:PROT <current>
To enable OCP shutdown
:
SOUR:CURR:PROT:STAT <on-off-state>
To set the under-current protection level:
SOUR:CURR:PROT:UND <current>
To enable UCP shutdown:
SOUR:CURR:PROT:UND:STAT <on-off-state>
To check if a protection mechanism was tripped:
SOUR:VOLT:PROT:OVER:TRIP?
SOUR:VOLT:PROT:UND:TRIP?
SOUR:CURR:PROT:OVER:TRIP?
SOUR:CURR:PROT:UND:TRIP?
Alternatively, you can query the status register. See
Appendix B. “SCPI Command
