Device Description
In this example you can see that the voltage source S1 (bank A) is fed by the source S5
(24V power supply). The consumption at S1 is also reflected at S5.
Measuring points of the voltage sources
The device has a current and voltage measurement at the following locations in the
device:
·
Bank A 5V DC (Bank monitor) display on the website Bank A
·
Bank B 12V / 24V DC (Bank monitor) Display on the website Bank B
·
Bank C 12V / 24V DC (Bank monitor) Display on the website Bank C
·
Bank D 12V / 24V DC (Bank monitor) Display on the website Bank D
·
24V power supply (Supply monitor) Display on the website as "S5"
·
230V power supply (Energy monitor & RCM type A) on the website as "L1 Meter12
Critical voltage and current values
If the voltage measurement falls below minimum values, the voltage indicator LED on the
front panel changes from green to red. If the current of a bank or 24V power supply ex-
ceeds a critical value, the voltage indicator LED flashes.
Error case
5V
12V
24V
230V
Voltage undershot (red
LED)
< 4,75V
< 11,4V
< 22,8V
< 80V
Current exceeded (flashing
LED)
> 8,8 A
> 6,0 A
> 12,5 A
> 16 A
Here the voltage at bank D has fallen below 11.4V.
Use of eFuses
In the device, the DC power sources are protected by resettable electronic fuses
(eFuses). These fuses are triggered by short circuit or overload. If an eFuse is triggered,
the output is switched off. The device then also automatically switches off the port (front
