Power Supply Function
At this time, 10Ω in sink mode (according to the formula I=U/R, sink current
is 80÷10=8A), due to the limitation of Is=–5A in CC priority mode, the actual
sink current is 5A, and the instrument is working In CC mode. If Sink Res is
set to 20Ω, the sink current is 4A, which is within the limit of Is, so the instru-
ment works in CR mode at this time.
4.4.4 Set the Output-On/Output-Off Delay
You can set the output-on/output-off delay time within the range from 0 seconds
to 60 seconds.
• On Delay: Indicates from the time that a command to turn on the output is re-
ceived until the output actually turns on.
• Off Delay: Indicates from the time that a command to turn off the output is re-
ceived until the output actually turns off.
The procedures to set the output delay time are as follows.
1. Press the composite keys [Shift]+[V-set] (Config) on the front panel to enter
the configuration menu.
2. Press the up/down key or rotate the knob to select On Delay or Off Delay,
and press [Enter] to confirm.
3. Set the output-on/output-off delay time and press [Enter] to confirm.
4.5 Protection Function for Power Supply
The IT6000B series power system provides the general protection functions
such as overvoltage, overcurrent, overpower, undercurrent and undervoltage
protection. The corresponding protection parameters can be configured in the
Protect menu. In addition, the power system also provides over temperature
protection and Sense reverse connection protection.
The descriptions of Protect menu are listed in the table below.
