Output resistance setting
3.11 Setting Output Rise Time/Fall Time
Rise/fall time is the time taken for one voltage point to rise/fall to the other under
the output status is ON. When view the fall time that voltage falls to 0V, set 0V
through [V-set]. After press [Enter] to confirm, voltage will fall based on the set
fall time.
This series of power supply is supported the rise and fall times in all modes
(Source: CV, CC, CP, Load: CC, CP), the range of time is 0.001S~24H.
1. Press [Shift] + [V-set](Setup) to enter power supply setting screen.
2. Select “Source”, press [Enter].
Or, the user can select “Load” to set the load slope.
3. Select “Slope”.
You can set the rise/fall times for voltage, current and power. The unit is
second (S). Each setting can be selected through the Up/Down key. Adjust
the rise time through the numeric key, Up/Down key or knob. After input,
then press [Enter] or [OK] for confirmation.
V-Rise/ V-Fall: Voltage rise/fall slope.
I-Rise/ I-Fall: Current rise/fall slope.
P-Rise/P-Fall: Power rise/fall slope.
Note
The drop rate of the voltage is affected by the internal load input current. Setting the load
input current to the maximum will get the drop rate of the voltage up. Please refer to the Set
load input in 3.14 Load Function for more detailed setting.
3.12 Protection Function
IT6500C Series provides OVP, OCP, OPP for power supply as well as OCP and
OPP for the load. In addition, this power supply also provides OTP, Sense
reverse protection, power-down protection and input under-voltage protection.
In case of protection, please check fault reason and remove fault. Press the
[Esc] key to disarm protection status.
OVP
User can enable the over voltage protection function and set the protection
value in setup menu, Over Voltage Protection will be triggered when the voltage
exceeds the protection value. Many reasons could cause over voltage
protection. For example, caused by internal defect,misoperation,or too high
external voltage.
Once the power supply is over voltage protected,will the output be shut down at
once, and “Prot” indicator lamp will be lit, and prompt “Over Voltage” will be
displayed on VFD screen. Please avoid inputing a external voltage higher than
120% rated value, or the instrument will be damaged.
When the power source is in OVP state, you should check the external cause
firstly. When the external factors are excluded, please press [On/Off] button.
Then the unit could have a output voltage again. If in remote control mode, you
should clear the OVP state, then could you open the output by OUTP ON
