- IUoUO charging curve, constant voltage and constant current Battery-Life Test function (Battery Care)
- Four charging modes: Recovery, Boost, Absorption, Float
- Protected against short circuit and reverse polarity
- Output signal (contact-free) for discharged or damaged battery, Modbus, main and back-up
- Combinable with DC UPS series
- Wall mounted
- Protection degree: IP30
- Complies with EN54-4
Safety DC-UPS is an uninterruptible power supply unit for fire protection and voice alarm systems. 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.
You can integrate the device with the whole range of CBI ADEL system batteries and different battery sizes (from 1.2 to 18 Ah). Its protection degree is IP30. The maximum 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, The CBI devices switch automatically the battery to load without any output interruption.
The battery is tested, charged and its charging temperature is 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 signal mainly indicates a problem related to:
- a battery fault (Internal Impedance)
- a back-up
- a rectifier fault.
SFP54.4 can be connected through other devices by ADELBus in a loop configuration.
For instance, CBI2801224A is performed for this configuration. In this way, you can manage additional devices with only one DPY351 display.
It is also possible:
- to detect electromagnets for fire doors
- to detect record switch detectors, ground leakage, and environmental temperature
- to control light or output sound alarms.
Installing an 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.
