DC power systems

DC power-S: Compact, flexible and modular DC power supply systems
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 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 30,
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, a NiCd electrolyte level detection input and six additional relays.

Applications: Redundant protection for critical applications
Salicru’s DC power-S energy systems provide a high-level power supply to always critical telecommunications systems,
ensuring excellent operation without unexpected outages. Because of its modular nature, it can also be expanded according to
needs, thereby optimising the investment. Typical applications include: fixed and mobile communications networks, broadband
access networks and data and telecommunications networks.
