The PSU-60 is a power supply unit with an integrated
battery charging device.
Functions
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 following applies to 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.
