Salicru has just launched its new DC POWER-S range, which provides a high-level power supply to always critical telecommunications systems, ensuring excellent operation without unexpected outages. Its main applications are mobile and fixed communications networks, broadband access networks and data and telecommunication networks.

DC systems are devices that either convert alternating current into direct current (rectifiers, chargers) or direct current into alternating current (inverters). Such DC systems can store power in an accumulator battery, enabling an uninterrupted supply of DC or AC (through an inverter).

Salicru’s new DC POWER-S systems include DC-S rectifier modules available in power ratings of 1,000, 2,000 and 2,700 W and output voltages of 48, 110 or 125 Vdc. Its modular design enables up to 4 modules to be installed in a 19” 2U subrack, achieving very high power density and enabling the installation to expand according to growth needs, thereby optimising the investment. It also features a control and monitoring system that enables the entire system to be managed: input and output measurements, battery charging currents, control of priority and non-priority loads and outside communication channels.

Each control system can manage a maximum of 30 rectifiers, enabling systems to achieve power ratings of up to 81 kW with N+n redundant configuration options. Its communications module includes three programmable relays, a battery temperature sensor and an RS-232/485 channel in its basic version and an Ethernet/SNMP adapter slot, an NiCd electrolyte level detection input and six additional relays in its extended version. All contained in a fully closed cabinet with the possibility of including batteries.
