Salicru's DC power-S energy systems feature the following components: DC-S rectifier modules, subracks, a control and monitoring system, a communications module and a DC distribution unit, all situated in a closed cabinet with the possibility of including batteries.
DC power-S system rectifier modules are available in power ratings of 1000, 2000 and 2700 W and output voltages of 24, 48, 110 and 125 Vdc. Its modular design enables up to 4 modules to be installed in a 19" 2U subrack, achieving very high power density.
The control and monitoring system manages the entire system: input and output measurements, battery charging currents, control of priority and non-priority loads and communication channels with the outside. The maximum number of rectifiers controlled by a control system is 3 , enabling systems to achieve power ratings of up to 81 kW with N+n redundant configuration options.
The basic version of the communications module has: three programmable relays, a battery temperature sensor and an RS-232/485 channel. Extended version features a slot for an Ethernet/SNMP adapter, an NiCd electrolyte level detection input and six additional relays.
