APC SCL500RMI1UC Smart-UPS Line Interactive 500VA Lithium-ion

What the SCL500RMI1UC provides

APC SCL500RMI1UC is listed by APC as Smart-UPS Line Interactive 500VA Lithium-ion Rackmount 1U 230V 4x IEC C13 outlets SmartConnect Port Short Depth, with a rated output of 500 VA (400 W).

It is fed from 230 V AC 1 phase and supplies 230 V AC 1 phase as a sine wave. The listed battery type is li-ion (lithium-ion) internal included. The recorded mounting mode is rack-mounted.

The APC SCL500RMI1UC is listed with line interactive topology. A line-interactive design corrects normal mains variations with automatic voltage regulation and switches to battery power when the supply fails. It is commonly used for servers, networking equipment and workstations where sags, surges and short outages are the main concern.

The output waveform is listed as sine wave. A sine-wave output is the safer choice for equipment with active power factor correction and for sensitive electronics. The listed ratings of 500 VA and 400 W correspond to a power factor of 0.8. Size the load against the watt rating as well as the VA rating, and keep margin for future equipment.

Technical specifications

Electrical interface and runtime notes

Output connections: 4 IEC 60320 C13. Input connection: IEC 60320 C14. Input frequency: 50/60 Hz +/- 3 Hz auto sensing. Communication and expansion: Serial port / USB port / SmartConnect port.

Load sizing should be checked against both the VA and the watt rating, and runtime depends on the connected load, battery condition and ambient temperature. Confirm these points against the product documents before ordering.

Physical data and environment

Dimensions are 44 mm x 432 mm x 232 mm (H x W x D), and the unit weighs 4.06 kg. Colour: black with silver front bezel.

Listed operating limits: operating temperature 0…40 °C; relative humidity 0…95 % non-condensing; operating altitude 0…10000 ft; protection IP20; acoustic level 45 dBA.

Certifications: C-Tick / CE / EAC / RCM / UK PSTI. Standards: EN/IEC 62040-2:2006/AC:2006 / EN/IEC 62040-2:2018. Warranty recorded by APC (months): 60.

Battery data listed for this model: type li-ion (lithium-ion) (internal battery included). Lithium-ion batteries are generally lighter and longer-lived than sealed lead-acid blocks, and the battery state can be monitored through the UPS management interface. Used batteries must be recycled according to local regulations.

Further electrical values recorded for the APC SCL500RMI1UC include: transfer time: 6 ms typical : 10 ms maximum; surge energy rating: 510 J. Use these figures when sizing upstream protection and cabling, and confirm them against the installation documents for the exact variant.

Communication and management details listed: UPS connectivity: Serial port / USB port / SmartConnect port; software compatibility: SmartConnect / IT Expert / PowerChute Serial Shutdown; software package: SmartConnect software for remote power monitoring feature availability varies by terms of use. Network cards, software and monitoring options should be matched to the facility monitoring system before ordering.

The mounting mode is listed as rack-mounted. The unit measures 44 mm x 432 mm x 232 mm (H x W x D) and weighs 4.06 kg, so check the available space and the floor or rack loading before delivery. It occupies 1U of rack space. Rack installation should be checked against the rack depth, rail kit and the clearance needed behind the unit for cables and airflow. Listed environmental limits: operating temperature 0…40 °C; relative humidity 0…95 % non-condensing; altitude 0…10000 ft. Equipment rooms in the Gulf region often run warm, so leave ventilation clearance and keep the unit away from direct heat sources.

Certifications listed: C-Tick / CE / EAC / RCM / UK PSTI. The warranty period recorded in the product data is 60 months. If a project requires certificates or test reports, include that request with the quotation request.

How the SCL500RMI1UC is used in APC Smart-UPS systems

Smart-UPS is the APC range most often found under servers, network switches, storage and branch-office IT. The line-interactive models correct everyday voltage swings with automatic voltage regulation instead of draining the battery, and transfer to battery within milliseconds when the supply fails. Many units carry a SmartSlot for a network management card, so the UPS can be monitored over the network and can trigger an orderly shutdown of connected servers through PowerChute software.

The APC SCL500RMI1UC is a complete UPS rather than a spare part, so the selection starts from the load. Add up the real power of the connected equipment in watts, compare it with the watt rating of the UPS as well as the VA rating, and keep about 20 to 25 percent margin for growth and for inrush current when equipment restarts. Then define the runtime the site needs: a few minutes is enough to ride through short interruptions or to let a standby generator start and stabilise, while longer outages call for external battery capacity where the model supports it.

In the product data for the APC SCL500RMI1UC, it is rated 500 VA and 400 W; it uses line interactive topology; its battery technology is listed as li-ion (lithium-ion) internal included; it occupies 1U rack unit(s). These values are the starting point for matching it to the rest of the installation.

Site conditions in Oman and the GCC for the SCL500RMI1UC

Check the nominal voltage of the site against the input and output ratings in the specification table: Oman uses 240 V single-phase and 415 V three-phase at 50 Hz. Because it is listed for both 50 Hz and 60 Hz, the same model can be used on the 50 Hz grids of Oman, the UAE and Qatar and on the 60 Hz grid of Saudi Arabia. The listed operating temperature tops out at 40 °C. Summer shade temperatures in Muscat, Sohar and the interior regularly pass 45 °C, so the equipment belongs in an air-conditioned room or cabinet rather than an open plant area. Battery temperature has the biggest effect on service life: as a rule of thumb, the life of a valve-regulated lead-acid battery roughly halves for every 10 °C above 25 °C, so a room held at 20 to 25 °C pays back in fewer battery replacements.

The heat dissipation of 41.61 Btu/h has to be included in the cooling budget of the room. Dust and humidity are the other two regional factors: fine dust blocks fans and filters, and coastal humidity and salt attack contacts, so a clean, sealed room and regular inspection protect the investment. Many sites in the region run the UPS downstream of a standby diesel generator. The UPS carries the load during the start-up of the generator and smooths its voltage and frequency, so the generator should be sized with margin for the UPS input and battery charging current.
