Salicru's new DC POWER-S energy systems include DC-S rectifier modules, available in power ratings of 1,000, 2,000 and 2,700 W and in output voltages of 48, 110 or 125 Vdc. Its modular design allows up to four modules to be installed in a 2U 19” subrack, achieving very high power density and enabling expansion as needed, thus optimizing investment. It also features a control and monitoring system for
managing the entire system: input and output measurements, battery charging currents, control of priority and non-priority loads, and external communication channels.
The maximum number of rectifiers controlled by a single control system is 30, enabling systems up to 81 kW, with the option of N+n redundant configurations. The basic version of its communication module includes three programmable relays, a battery temperature sensor, and an RS-232/485 channel. The extended version adds an Ethernet/SNMP adapter slot, an electrolyte level detection input for Ni-Cd batteries, and six additional relays. All of this is housed in a
fully enclosed cabinet with the option to include batteries.
