10kVA true online UPS for high-capacity critical loads

The Symphony SPY10KiRTB is a 10kVA / 10000W single-phase, online double-conversion UPS designed by Uniti Power for data rooms, larger comms and network installations, healthcare and laboratory systems, industrial processes and other high-value loads. It comes as a complete 5U system, a 2U power module with a 3U battery module, and installs in a 19-inch rack or as a tower.

Because the inverter carries the load all the time, equipment is protected from power cuts, sags, surges, frequency variation and electrical noise, with no break in the output when the UPS moves to battery. Up to 95% online efficiency, ±1% output regulation and parallel operation of up to three units give larger sites both capacity and resilience.

Where the SPY10KiRTB is used

Typical applications include data centres and server rooms, IT and telecoms networks, enterprise and edge computing, healthcare and laboratory equipment, and industrial and manufacturing systems.

Power quality and efficiency

• 0ms transfer to battery: the output continues without a break when the mains fails.
• Regulated output: ±1% voltage accuracy, under 1% THDv on linear loads and a 3:1 crest factor.
• Wide input window: 160-275V at full load, and down to 110V with derating, to ride through voltage dips without discharging the batteries.
• Clean input: input power factor above 0.995, with THDi below 3% on linear loads and below 5% on non-linear loads.
• Efficiency: up to 95% in online mode and up to 98% in ECO mode, with a 10ms transfer from ECO to the inverter.
• Overload capacity: 105-125% for 10 minutes and 125-150% for 30 seconds in line mode.
• Frequency converter mode: 50Hz / 60Hz conversion (CVCF) at up to 60% load.

Runtime and battery expansion

The supplied 3U battery module holds 20 x 12V 9Ah batteries (240V DC), giving a typical 3.8 minutes at the full 10000W load and 9.3 minutes at 5000W. Up to five additional EBM2409RT3U external battery modules can be added, six battery modules in total, for extended runtime.

The 2A charger, adjustable from 0 to 4A, recharges the supplied batteries to 90% in around 3 hours. The Run Time tab estimates runtime at any load.

Runtimes are typical values for new, fully charged batteries at 25°C, provided as a guide only. Actual runtime depends on battery age, temperature and the type of load.

Parallel operation and redundancy

With the optional SPYPK parallel card, up to three Symphony 6kVA or 10kVA units can run in parallel, either to increase capacity or to provide N+1 redundancy for loads that cannot afford downtime.

Installation

Input and output are hardwired terminal connections (L / N / PE), so the SPY10KiRTB is connected into the electrical installation rather than plugged in. The power module measures 438 x 573 x 86.2mm (2U) and the battery module 438 x 593 x 129mm (3U). Rack ears and tower feet are included, the optional SPYRAIL6-10 rail kit supports the system in a 19-inch cabinet, and the dot-matrix LCD rotates for either orientation.

The SPY10KiRTB operates from 0 to 50°C, with output derating to 50% between 40 and 50°C.

Monitoring, communications and safe shutdown

USB (HID), RS232, a programmable dry input and output, and an emergency power off (EPO) input are fitted as standard. The intelligent slot accepts an optional network management card, Modbus card or AS400 dry-contact card, and an optional WLAN module is available. WinPower G2 monitoring software provides status, alarms and controlled shutdown of connected systems.

Standards, warranty and support

The SPY10KiRTB is CE marked and built to IEC/EN 62040, the international standard for UPS systems. It meets Category C3 for conducted and radiated emissions, with immunity tested to IEC/EN 61000-4-2, -4-3, -4-4 and -4-5.

Registered Symphony products in the UK carry a 6-year warranty on the UPS electronics and 2 years on batteries and accessories, from the original date of purchase. Installation and commissioning is recommended but is not a condition of the warranty. See warranty information for full terms, and register your UPS once it is installed.

What's in the box

SPY10KiRTB 2U power module, 3U battery module, USB cable, rack ears, tower feet and user manual. Power cables are not required because input and output are hardwired. An RS232 cable and the SPYRAIL6-10 rail kit are available separately.

Symphony SPY10KiRTB questions answered

Does the SPY10KiRTB include batteries?
Yes. The SPY10KiRTB is supplied with a 3U battery module containing 20 x 12V 9Ah batteries.

How much load can the SPY10KiRTB support?
Up to 10000W. Its output power factor is 1.0, so the VA and watt ratings are the same.

How long will the SPY10KiRTB run on battery?
About 3.8 minutes at full load and 9.3 minutes at half load on the supplied battery module, extending to 37.6 minutes at full load and 92.5 minutes at half load with five EBM2409RT3U modules.

Can SPY10KiRTB units run in parallel?
Yes. Up to three units can be paralleled for capacity or N+1 redundancy using the SPYPK parallel card.

How is the SPY10KiRTB connected?
Through hardwired L / N / PE terminals on both input and output. Professional installation and commissioning is recommended.
