It is possible to configure the device by choosing two different types of display, DPY351 and DPY353, while meeting all requirements of the EN54-4 standard.
The device can be integrated with the whole range of CBI ADEL system batteries and with different battery sizes (from 1.2 to 18 Ah). Its protection degree is IP30. Its maximum total output can reach 20 A and it can be distributed between load and battery, depending on the type of CBI chosen. The complete range of power-supply output is 12-24-48 VDC. CBI devices can load, recharge and test batteries. For Recharge-&-Testing battery features, please refer to the Technical Data of the CBI Line.
In case of failure, CBI devices automatically switch the battery to the load without any output interruption. The battery is tested, charged and its charging temperature compensated through the external temperature sensor. With models DPY351 and DPY353, you can monitor the state of the device. An alarm will directly report a signal through dry contact or by Ethernet. The alarm mainly indicates a problem such as a battery fault (Internal Impedance), a problem related to the back-up or a rectifier fault.
SFP54.4 can be connected through other devices by ADELBus in loop configuration. For instance, CBI2801224A is performed for this configuration. In this way, you can manage additional devices with only one DPY351 display. With DPY531, it is also possible to detect electromagnets for fire doors; record switch detectors, ground leakage and environmental temperature; as well as to control light or output sound alarms. Installing a LDC (3.5”) on the front panel, enables you to monitor the system condition, i.e., event log, alarm, battery, back-up, output current (and voltage) during the loading, as well as the battery side connected on the loop. There is also a keyboard on the display of DPY351 for the configuration and maintenance of the device. |
