Short Description of the UPS
The UPS (uninterruptible power supply) supplies the connected device for a
certain period of time with voltage if the supply voltage (+24 VDC) fails.
This UPS is a DC UPS. That means that the input voltage as well as the output
voltage of the UPS is +24 VDC. Instead of an accumulator, an AC power supply
unit is installed that is supplied by a main UPS when the 24 V voltage supply
fails. Thus, an output voltage of 24 V remains.
The UPS is able to provide the connected device with 24 V and 2.5 A for three
minutes max. The communication between UPS and connected device occurs
via a serial interface (XCOM1). The UPS consists of the following components:
●
Enclosed metal housing.
●
Power unit 115/230 VAC on +24 VDC integrated in the device. This power
supply unit functions as an accumulator if the +24 V supply voltage for the
UPS fails or is switched off.
●
Display and operating components are arranged accessibly on the front
panel.
●
Integrated burst and surge protection for the connected device.
