Enhanced protection for mid-range systems with single-phase power supply
Salicru's SLC 4000 TWIN PRO2 4kVA UPS features on-line double conversion technology, currently the most advanced for the protection of critical systems as it provides a fully stabilised and filtered sinusoidal supply voltage.
The Salicru SLC TWIN PRO2's output voltage is always single-phase, featuring a single-phase input of 4 kVA. The SLC 4000 TWIN PRO2 4kVA UPS provides a unitary output power factor, the most optimum for systems and environments with high energy needs. Adaptability is another important feature thanks to the numerous operating modes available: On-line, Batteries, Eco-mode, Bypass, Frequency converter and Parallel redundant.
The possibilities of control and monitoring are varied: on the one hand, an LCD display + keypad for local operation of the device, and, on the other, various communication options (USB HID and RS-232 interfaces, and slot for SNMP, RS-485 and AS-400 cards) that enable the UPS to be integrated into standard or virtualised platforms for management, incident notification and remote maintenance.
On-line double conversion and DSP control technology.
Output power factor PF=1
Compact tower format for space saving.
Active power factor corrector for all input phases.
Multiple operating modes for better adaptability.
Equipped for parallel operation as standard, up to 3 devices.
USB and RS-232 interface for all models as standard.
Monitoring software for Windows, Linux, Unix and Mac.(downloadable)
Intelligent slot for SNMP/RS-485/optocoupler cards.
Eco-mode operation for increased efficiency.
Backup extensions available for all power ratings.
Frequency conversion function.
EPO – emergency power off.
Manual and/or automatic programmable battery test.
SLC Greenergy solution.
Double voltage conversion (AC/DC + DC/AC), providing the best degree of safety to loads
In the event of power failure, the loads continue to be powered by means of batteries
In the event of any eventuality (incident, overload, etc.), the loads continue to be powered by the input voltage.
Adaptation of the output frequency to the needs of the load (50/60 Hz or 60/50 Hz).
Increased efficiency up to 99%, with immediate availability of full power.
Increased safety (N+1) or capacity, with configurations of up to 3 devices.
Salicru's SLC TWIN PRO2 series is the best option for providing a secure power supply to ERP systems, Business Intelligence, CRM solutions, intranets/extranets and corporate networks in the event of a wide range of possible disturbances (micro power outages, voltage fluctuations, frequency variations, harmonics, transients, etc.), which can cause irreparable damage or incur high costs in all of these critical systems.
