►Visit TVR Online Shop for DC UPS |
The range of EN54-4-certified auxiliary power supplies for firefighting systems consists of two models: SFP120W and SFP240W, available in black or white and certified for currents up to 5A and 10A and for use with batteries up to 40Ah. The two models are certified according to EN 54-4:1997 + A1:2002 + A2:2006.
The CBI245A is used with the (SFP120W) and CBI2410A with the (SFP240W). The are installed inside the panels. The DC-UPS are equipped with advanced charging curves and internal battery impedance control that enable extended battery life. The CBI series of DC-UPS protect batteries from deep discharge by promptly signaling the low battery alarm.
In the event of a grid failure, CBI devices automatically switch the battery to the load without any output interruption. |
|
Both models are integrated with the new MRF102 2-channel electronic fuse, which allows the operator to set load protection currents from 1A to 10A.
Installed on the outside of the panels is the DPY353 LED display, which displays the operation of the auxiliary power supply and allows the operator to monitor the charge and health status of the connected batteries. |

| Any DC-UPS model can be installed inside the SFP panels, ensuring an EN54-4 and 12101-10 compliant solution. |
Monitoring unit: DPY351
The DPY351 LCD intelligent display, can be mounted on the door of the SFP panel. The DPY351 allows the user to manage multiple DC-UPS units as well as monitor, configure, store and connect remotely via ETHERNET TCP/IP and SNMP communication protocol.
Gateways and Protocols
DPY351 is a powerful tool in addition to being a gateway:
- HTTP Web Server for device configuration and management via Ethernet with dynamic or static IP
- Modbus TCP/IP Ability to configure a set of default values. Allow unique identification of the unit in the network
- SNMP v2c A list of parameters of connected devices is provided that can be viewed remotely or with SNMP. Each parameter (OID), is marked one by one to a Modbus RTU register
- MQTT Allows the DPY351 to connect to the ADELView System Cloud for remote power monitoring of devices connected to the DPY using Modbus or CANbus
