SL20KHB01 UPS at a glance

The APC SL20KHB01 is an uninterruptible power supply from the APC power protection range, rated at 20000 VA (20000 W).

It is fed from 400 V 3 phases and supplies 230 V / 400 V 3 phases. The recorded mounting mode is not rack-mountable.

The listed ratings of 20000 VA and 20000 W correspond to a power factor of 1. Size the load against the watt rating as well as the VA rating, and keep margin for future equipment.

Electrical interface and runtime notes

Output connections: Hard wire 4-wire (3P + E) for 1 zone(s) / Hard wire 5-wire (3P + N + E) for 1 zone(s) / Hard wire 3-wire (3P) for 1 zone(s) / Hard wire 4-wire (3P + N) for 1 zone(s) / Hard wire 4-wire (3P + PEN) for 1 zone(s). Input frequency: 50 Hz programmable +/- 0.5 / 1 / 2 / 4 / 6 / 8 % / 60 Hz programmable +/- 0.5 / 1 / 2 / 4 / 6 / 8 %.

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 140 cm x 100 cm x 80 cm (H x W x D), and the unit weighs 323.64 kg. Colour: dark green (ncs 7020-b50g) / light grey (ncs 2703-g84y).

Listed operating limits: operating temperature 0…40 °C; relative humidity 0…95 %; operating altitude 0…3333 ft; acoustic level 52 dBA.

Certifications: C-Tick / CE / TÜV. Standards: EN 50091-1 / EN 50091-2 / ISO 9001 / ISO 14001. Warranty recorded by APC (months): 12.

Further electrical values recorded for the APC SL20KHB01 include: bypass type: Built-in static bypass; crest factor: Unlimited; efficiency: 96 % (full load). Use these figures when sizing upstream protection and cabling, and confirm them against the installation documents for the exact variant.

The mounting mode is listed as not rack-mountable. The unit measures 140 cm x 100 cm x 80 cm (H x W x D) and weighs 323.64 kg, so check the available space and the floor or rack loading before delivery. It occupies 0U of rack space. Listed environmental limits: operating temperature 0…40 °C; relative humidity 0…95 %; altitude 0…3333 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 / TÜV. The warranty period recorded in the product data is 12 months. If a project requires certificates or test reports, include that request with the quotation request.

The SL20KHB01 within the APC Silcon range

Silcon is the APC range of large three-phase UPS systems, used for data centres, industrial processes and large technical buildings. It is based on the delta-conversion on-line principle, which protects the load with a continuously running inverter while keeping the input power factor high and input current harmonics low.

The APC SL20KHB01 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 SL20KHB01, it is rated 20000 VA and 20000 W; it occupies 0U rack unit(s). These values are the starting point for matching it to the rest of the installation.

Applying the SL20KHB01 on sites in Oman and the GCC

Low-voltage three-phase networks in Oman run at a nominal 415 V, 50 Hz, and most GCC countries at 400 V or 415 V, so confirm that the input voltage window of the system covers the measured supply on site. 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 3207 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. At 323.64 kg the unit needs two people or lifting equipment for installation, and rails rather than a shelf if it goes into a rack.

Ordering checklist for the SL20KHB01

The following details help confirm compatibility before a quotation is issued:

• The load to be protected in watts and VA, with the share of critical equipment
• The runtime needed on battery, and whether a standby generator is installed
• Input and output connection types required on site (input / Hard wire 4-wire (3P + E) for 1 zone(s) / Hard wire 5-wire (3P + N + E) for 1 zone(s) / Hard wire 3-wire (3P) for 1 zone(s) / Hard wire 4-wire (3P + N) for 1 zone(s) / Hard wire 4-wire (3P + PEN) for 1 zone(s))
• Rack or tower installation, and rack depth if rack-mounted
• Whether a network management card or monitoring is required
• The delivery location in Oman (for example Muscat, Sohar, Duqm or Salalah) or elsewhere in the GCC, and the required date

Other APC UPS systems, batteries and accessories and Schneider Electric equipment can be combined in one quotation.
