RackPower 20kVA Three Phase Online Tower UPS – Long Backup (TT020EL)

RackPower 20kVA Three Phase Online Tower UPS – Long Backup

True Online Double Conversion | Three Phase | 20000VA/20000W | Model TT020EL

RackPower’s 20kVA Three Phase Tower UPS is built for critical sites that need extended runtime, pairing true online double-conversion protection with external battery banks sized to your backup requirement. It suits larger server and comms rooms, building services and critical commercial loads. With a true power factor of 1.0, up to 97% online efficiency, a 3-level topology and full digital control, it delivers continuous, clean, regulated power with zero transfer time. It delivers twice the capacity of the 10kVA in the same compact tower footprint.

Key Features & Benefits

True Output Power Factor of 1.0

• Delivers the full rated power—20000W from 20kVA—with no compromise on capacity.

High Online Efficiency – Up to 97%

• 3-level topology and full digital control reduce energy waste, minimise heat and cut electricity costs.

Long-Backup Design with 10kW Charger

• Designed for external battery banks. The charger is rated at 50% of output (10kW) to recharge extended-runtime battery banks.

Wide Input Voltage Range (304–478Vac)

• Operates reliably on unstable mains or generator supply without switching to battery, preserving battery health. Continues to run down to 228Vac with power derating.

Clean Input – PF >0.99, THDi <2%

• Minimal impact on the upstream supply and generator, with no need for oversized input cabling or switchgear.

Flexible Output Configuration

• Three phase in / three phase out as standard. Three-in/one-out or one-in/one-out is available as an option, rated at 20kVA.

Intelligent Battery Management

• Extends battery life through smart charging and real-time battery diagnostics.

Self-Aging Function

• Enables automated testing without external load banks—saving energy and simplifying commissioning and maintenance.

Auto Fault Waveform Recording

• Captures fault events automatically for faster diagnostics and fault-finding.

7-Inch Touch LCD

• Real-time system monitoring and control through an intuitive touchscreen with LED status indicators.

Robust Overload Capacity

• 110% for 1 hour, 125% for 10 minutes, 150% for 1 minute and >150% for 200ms. Handles half-wave loads, with a crest factor of 3:1.

Comprehensive Communications

• USB, RS232, RS485, dry contacts, Ethernet and cold start as standard. SNMP card, AS400 card and parallel kit available as options.

Parallel Capable

• Supports parallel operation for N+1 redundancy or added capacity with the optional parallel kit.
