SLC TWIN PRO3 4-10 KVA: Robustness, energy efficiency and extended connectivity: the best combination to protect your productive environment

Salicru’s SLC TWIN PRO3 series of uninterruptible power supplies (UPSs) is the successor to the prestigious SLC TWIN PRO2 family, offering improved functionality and representing a step forward in terms of technology. The range starts at 4 kVA and includes 5, 6, 8 and 10 kVA models. There are also specific B1 versions for extended backup, available in 6 and 10 kVA power ratings.

The power factor of 1, increased energy efficiency and multiple operating modes give the SLC TWIN PRO3 a high level of added value in technical terms.

It is the fourth incarnation of the SLC TWIN series and represents a consolidation of the on-line single-phase double conversion UPSs we have been offering to the market for over 12 years. This latest edition maintains the series’ characteristic robustness while adding cuttingedge technology in the form of complete connectivity that will meet the technological expectations of even the most demanding users.

Its versatility in terms of communication deserves particular mention. The smart slot is joined by direct connections to the native Ethernet, USB and RS-232 ports or a Wi-Fi dongle. This broad spectrum of connectivity is complemented by the NIMBUS app and website access, which offer multiple options for monitoring and interacting with the connected devices, thereby enabling simultaneous viewing of all of the connected Salicru devices (even if they are from different series).

Applications: Critical and sensitive loads that require close supervision
Salicru’s SLC TWIN PRO3 series is the best option for ensuring continuity with constant and precise monitoring. Critical environments that maintain highly productive structures, such as ERP systems, Business Intelligence (BI), CRM solutions, networks, etc. need to be backed by the kind of energy security provided by the SLC TWIN PRO3 series, which also protects them against frequency and voltage variations and other types of disturbances that can affect the network.

Flexibility at the user’s fingertips
The SLC TWIN PRO3 series gives users the option of configuring the device as a frequency converter (annulling the no-battery alarm), while also enabling full configuration of the charger and battery voltage as well as operating as an output transformer. Users can even take advantage of this adaptability after the device has been installed, thereby enabling them to reconfigure its functionality when needed.

Increased battery life expectancy
Beyond the quality of their electronic components, the success of our uninterrupted protection and supply systems lies in the intelligent and optimised use of the charge and discharge cycles of the energy storage units, which can result in an increased battery life expectancy of up to 50% under optimum operating conditions.

Unlike other UPSs that subject their batteries to short and frequent charges, the SLC TWIN PRO3 series is able to optimise battery use through “rest periods” in which the battery does not receive any current at all, provided it has enough charge to guarantee the provision of backup.

Vigilant protection and connectivity
The inclusion of an Ethernet port and the optional Wi-Fi device enables the SLC TWIN PRO3 series to be integrated into an IoT environment. Through the cloud, our NIMBUS app and the website, developed wholly within SALICRU’s Connected Software department, users can monitor the status of their devices in full, receive information and alarms, carry out remote battery tests, and much more.

The immediacy offered by the system’s connectivity directly ensures the continuity of the connected loads, and consequently the continuity of the productive activities with them.

In terms of hardware, the over-voltage cut-off device (OVCD), fan-block detection system, overheating sensor, overload alarm and external-battery detection system ensure constant automated monitoring of the overall system.
