Under Voltage Inhibit
When the under-voltage inhibit function is enabled by selecting a mode, the load will not sink current until the input
voltage rises above the voltage-on setting.
Press UVI Mode to specify the under-voltage inhibit mode:
– Off : Turns the under-voltage inhibit function off.
– Live : Turns the input off whenever the voltage drops below the voltage-on setting. Turns the input back on
when the voltage reaches the voltage-on setting.
– Latched : Lets the load sink current when the voltage subsequently drops below the voltage-on setting. An
under-voltage inhibit condition is annunciated by the UVI status bit.
Under-voltage inhibit is not available when loads are grouped or when the unit is operating in CV mode.
To set the voltage-on setting, enter the voltage-on value in the Voltage On field. The voltage-on value can be
programmed from 0 to 153 V.
Clears OVP, OCP and OPP Event
To clear the protection function, first remove that condition that caused the protection fault.
Press Protection Clear to clear the protection function and returns the input to its previous operating state.
From the remote interface:
To enable the over-current protection for input 1 and 2:
CURR:PROT:STAT ON, (@1,2)
To set the over-current protection delay time for input 1 at 0.1 seconds:
CURR:PROT:DEL 0.1, (@1)
To set the over-current protection delay timer start for input 1 to CC transition:
CURR:PROT:DEL:STAR CCTR, (@1)
To enable the over-power protection for input 1 and 2:
POW:PROT:STAT ON, (@1,2)
To set the over-power protection delay time for input 1 at 0.2 seconds:
POW:PROT:DEL 0.2, (@1)
To program a low-voltage limit (under-voltage inhibit) of 2 V, and enable the inhibit mode:
VOLT:INH:VON 2, (@1)
VOLT:INH:VON:MODE LIVE, (@1)
To clear protection for input 1:
INP:PROT:CLE (@1)
