SALICRU Usv Slc-4000-twin Rt3 Online Double Converter

On-line double conversion tower/rack IoT UPS from 4 kVA to 10 kVA with PF=1
Efficiency and reliability for the protection of critical data

Salicru’s SLC TWIN RT3 series of uninterruptible power supplies (UPS) ranges from 4 to 10 kVA and offers excellent electrical protection performance for critical server environments. Although the devices are designed to be incorporated into rack cabinets, they include all of the accessories and can be adapted for use in tower format. The models with a rating of 4 kVA and over include a power strip that can be rack-mounted or attached to the body of the UPS if the vertical format is chosen. This strip (also known as a power distribution unit or PDU) maximises the device’s electrical connectivity and enables the rapid connection/disconnection of the loads that are to be protected.

Users interact directly with the device via a dot matrix display that highlights important information by placing it in the centre of the screen, unlike traditional LCD screens.

Reliability, power density and immediacy of information are three of the key features that define the SLC TWIN RT3 series, as they make the biggest contribution to satisfying the demands of today’s users.

Reliability for IT environments

The perfect mode for ensuring productivity in data management. The SLC TWIN RT3 series provides reliable continuity of operation for IT systems, offering protection for server environments, voice and data networks, ERP systems, CRM solutions, document management, and more.

Vigilant protection and connectivity

The inclusion of an Ethernet port and the optional Wi-Fi device enables the SLC TWIN RT3 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 associated 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.

Improved length

In many cases, the depth of 19” rack-type cabinets is a significant factor. Consequently, when designing the SLC TWIN RT3 range we made sure to reduce its dimensions along the Z axis, while continuing to maintain a front height of 2U x 19” for our UPSs. The result is a range that offers high power density in a format that is just 600 mm deep. The corresponding batteries are supplied in a 3U format whose depth has also been reduced.

Multiple output options

The SLC TWIN RT3 series boasts a variety of options for connecting loads. The devices rated 4 kVA and over provide not only two IEC C13 quick-connection outputs and an input/output terminal block, but also a rackable strip with eight additional outputs (6x IEC C13 + 2x IEC C19). The strip comes with safety clips to enable secure fastening of the electrical connectors, and can also be mounted on the side of the UPS using the accessories provided.

Advanced internal temperature management

The SLC TWIN RT3 devices rated 4-10 kW and over are equipped with two sets of variable-speed fans, in order to optimise thermal conditions inside the device. The front set acts as a pump, while the rear set extracts the air immediately.

The resultant improvement in thermal conditions has a positive impact on the lifespan of the components, while creating a suitable working environment that enables the device to operate at full performance.

BM-R connectable manual bypass

The standout option for this series is the external manual bypass module. This bypass enables the user to manage the connected batteries and handle the connected UPS without having to interrupt the supply to the downstream network. Most importantly, it also incorporates two groups of programmable outputs that make it easy to assign critical and secondary loads.

This external module boasts four IEC C13 outputs and two IEC C19 outputs (evenly divided into two groups), as well as a terminal output. It can be mounted in rack format on the front as well as the back of the cabinet and comes with fastening lugs that allow the module to be lowered without the need for disassembly, thus maximising ease of access to the connections at the rear of the device.

The range of options does not end there, as the bypass also has two metal bracket that enable it to be mounted on the side of the unit when the user has positioned it in tower format.

Optional extended back-up time

The SLC TWIN RT3 retains the option to extend its backup through the use of additional battery modules in 3U rack format.

The modules are connected to one another and to the UPS via a solid Anderson aerial connector and an RJ45 cable, offering smart management.

The charging currents and bus voltage are selectable by the user, thereby ensuring maximum adaptation to the backup option chosen. For facilities that require a greater amount of current during the battery charging cycle, Salicru’s B1 range boasts a high-capacity charger while retaining the 2U format of the standard version.
