The PSU-60 includes the following LED voltage status indicators:
-
If the input voltage (AC) is greater than 85 VAC, the green LED lights up next to AC and the AC relay is closed.
-
If the output voltage (DC) is greater than 12 V or 24 V (depending on the mode), the green LED lights up next to DC and the DC relay is closed.
-
If the battery voltage is greater than 11 V or 22 V (depending on the mode), the green LED lights up next to BAT and the BAT relay is closed.
The PSU-60 includes the following the battery mode:
- If the input voltage is less than 85 VAC, the power supply switches to “Battery operation” mode and the yellow LED lights up next to BOP.
- The OFF button is only activated in “Battery operation” mode. Press this button to switch off the PSU-60.
- Restart is only possible when the alternating current supply is restored.
- This power supply unit can be switched to 12 V or 24 V mode. To do this, the switch must be configured as shown below, when there is no voltage input on the power supply.
