4 Using the Regenerative Power System
Set the Output Turn-On/Turn-Off Mode - RP793xA, RP794xA
This information applies to models RP793xA and RP794xA only.
The turn-on/turn-off setting only applies when the RPS is operating in voltage priority
mode. In current priority mode, the turn-on/turn-off behavior is always impedance.
The voltage priority turn-on and turn-off behavior can be set to either low impedance or high
impedance mode.
Low impedance mode is for devices like power converters. During output transitions, current is
sourced or discharged for fast output voltage response.
High impedance mode is for devices like batteries, where output transitions are controlled to minimize
output current.
When coupling is enabled, changing the turn-on setting also changes the turn-off setting and vice-
versa.
Front Panel Menu Reference
Select Output\Advanced\Tmode.
Select either High impedance or Low impedance for
turn-on an turn-off modes.
Check Coupled to couple the turn-on and turn-off
modes. Then press Select.
Enable the Output
Because of internal circuit start-up procedures and any installed relay options, OUTPut ON may take
tens of milliseconds to complete its function. OUTPut OFF delays may also be in effect. For more
information regarding output turn-on and turn-off delays, refer to
Front Panel Menu Reference
Press the On/Off key.
In addition to the front panel and SCPI Output On and Output Off commands, you can also use
OnCouple and OffCouple signals to enable and disable the output. Refer to
more information. When coupling is enabled, changing the turn-on setting also changes the turn-off
setting and vice-versa.
During a 1-cycle AC line dropout the unit may reboot. The output will remain off
after reboot until the operator reinstates the previous settings, either by the front
panel controls or using a computer program. This behavior is consistent with safe
operating procedures.
