APC SYA8K16I Symmetra LX 8kVA Scalable to 16kVA N+1 Tower

Role of the SYA8K16I in a power protection layout

The APC SYA8K16I gives the protected load a UPS from the Symmetra LX range sized at 8000 VA (5600 W) with 220 V AC 1 phase / 230 V AC 1 phase / 240 V AC 1 phase output.

It is fed from 220 V AC 1 phase / 400 V AC 3 phases / 230 V AC 1 phase / 240 V AC 1 phase / 380 V AC 3 phases / 415 V AC 3 phases and supplies 220 V AC 1 phase / 230 V AC 1 phase / 240 V AC 1 phase as a sine wave. The listed battery type is lead-acid battery, with a typical recharge time of 3 h. The recorded mounting mode is not rack-mountable.

The APC SYA8K16I is listed with on-line topology. In an online double-conversion design the load is fed from the inverter at all times, so connected equipment is isolated from mains disturbances and there is no transfer time when the mains supply fails. This approach is commonly chosen for servers, network cores and other sensitive loads.

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 8000 VA and 5600 W correspond to a power factor of 0.7. Size the load against the watt rating as well as the VA rating, and keep margin for future equipment.

Technical specifications

Power, battery and connection data

Output connections: Hard wire 3-wire (H N + E) for 1 zone(s). Input connection: 1 hard wire 3-wire (1P + N + E) / 1 hard wire 5-wire (3P + N + E). Input frequency: 45…65 Hz auto-sensing. Communication and expansion: Serial port / Available expansion slot / Pre-installed network management card 3.

Extendable runtime is listed as 1. Battery life is listed as 3…5 year(s).

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.

Site requirements and approvals

Dimensions are 937 mm x 483 mm x 726 mm (H x W x D), and the unit weighs 219.55 kg. Colour: black / silver.

Listed operating limits: operating temperature 0…40 °C; relative humidity 0…95 %; operating altitude 0…10000 ft; acoustic level 62 dBA.

Certifications: C-Tick / CE / GOST / VDE. Standards: EN 50091-1 / EN 50091-2 / EN 55022 class A / EN 55024 / EN 60950 / IEC 60950. Warranty recorded by APC (months): 24.

Battery data listed for this model: type lead-acid battery. The typical recharge time is 3 h. Sealed lead-acid batteries need no topping up in normal use but wear with age and heat, so replacement should be planned in advance and the battery state checked during routine maintenance. Used batteries must be recycled according to local regulations. Extendable runtime is listed as 1. Actual runtime always depends on the connected load, battery age and ambient temperature.

Further electrical values recorded for the APC SYA8K16I include: bypass type: Internal bypass (automatic and manual); crest factor: Up to 5 : 1; maximum output current: 36 A. 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 / Available expansion slot / Pre-installed network management card 3; graph display: 1. Network cards, software and monitoring options should be matched to the facility monitoring system before ordering.

The mounting mode is listed as not rack-mountable. The unit measures 937 mm x 483 mm x 726 mm (H x W x D) and weighs 219.55 kg, so check the available space and the floor or rack loading before delivery. Listed environmental limits: operating temperature 0…40 °C; relative humidity 0…95 %; 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 / GOST / VDE. The warranty period recorded in the product data is 24 months. If a project requires certificates or test reports, include that request with the quotation request.

How the SYA8K16I is used in APC Symmetra LX systems

Symmetra LX is a modular single-phase UPS built from hot-swappable power modules and battery modules in a rack or tower frame. With N+1 redundancy a failed module can be replaced while the load stays protected, and capacity or runtime can be raised by adding modules instead of replacing the whole UPS.

The APC SYA8K16I 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 SYA8K16I, it is rated 8000 VA and 5600 W; it uses on-line topology; its battery technology is listed as lead-acid battery. These values are the starting point for matching it to the rest of the installation.

Site conditions in Oman and the GCC for the SYA8K16I

The output can be set to 240 V, which matches the nominal 240 V single-phase supply in Oman. 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 3707 Btu/h has to be included in the cooling budget of the room.

Fine dust inland and humid, salty air on the coast are hard on electronics, so a sealed room, clean filters and periodic inspection of fans and terminals are part of a reliable installation. 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. At 219.55 kg the unit needs two people or lifting equipment for installation, and rails rather than a shelf if it goes into a rack.

What to send with an enquiry for the SYA8K16I

To confirm the right item and quote quickly, send the following with the part number:
