BEL Power Solutions Industrial Power Supplies - BEL POWER SOLUTIONS LDD960-UU, The BEL POWER Solutions LDD960-UU is a microprocessor-controlled unit that can perform two functions:DC-UPS rated 960 W / 20 A usable in any system 12 - 48 VDC or DC/DC converter (non-isolated) rated 960 W / 20 A usable in any combination of IN/OUT voltages 12 - 48 VDC.For the UPS function it may use one 12 V battery, independently of the operating load voltage. For any supply voltages (12 - 48 VDC) it may use also multiple battery configuration (10 - 60 VDC).LDD960-UU monitors the voltage coming from a DC power supply and in case of power failure a backup storage source supplies the energy to the load. In normal condition the battery is kept charged by an integrated battery charger supporting various battery chemistries.As a DC/DC converter (no battery present), the input voltage is converted to any output voltage as per the set-up (programmable by front keys or communication interfaces).
