DC POWER-S

DC power systems

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 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.

Application

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.

Accesories

Unit DC output voltage droppin

Unit DC output voltage droppin - SALICRU

Set of diodes used to drop the votlage and ensure that the DC output voltage doesn’t exceed the limits required by the loads.

Wireless-link communication

Wireless-link communication - SALICRU

An application that can be installed on tablets with the Android operating system to establish remote communication through a Bluetooth connection.

Extended communications module

Extended communications module - SALICRU

This enables the equipment’s communication functions to be extended by increasing the potential-free contacts from 3 to 9 and adding a digital input for electrolyte level detection (only for open lead or NiCd batteries).

Positive or negative output voltages

Positive or negative output voltages - SALICRU

Connection of one of the two DC output voltage poles to earth. DC negative pole connected to earth, positive output and positive pole connected to earth, negative output.
