Remote interface operation
Use the following commands to store and recall the power
supply state.
Programming the Overvoltage Protection
Overvoltage protection guards the load against output
voltages reaching values greater than the programmed
protection level. It is accomplished by shorting the output
via an internal SCR when the trip level is set to equal or
greater than 3 V, or by programming the output to 1 V when
the trip level is set to less than 3 V.
The following steps show how to set the OVP trip level, how
to check the OVP operation, and how to clear the
overvoltage condition.
Front panel operation
Setting the OVP level and enabling the OVP circuit
1 Turn on the power supply.
2 Select the output to be programmed.
*SAV {1|2|3|4|5} Store an operating state to
a specified location.
*RCL {1|2|3|4|5} Recall a previously stored
state from a specified
location.
“MEM:STAT:NAME 1, ‘P15V_TEST’” Name the storage location 1
as “P15V_TEST”.
