Overview

The UltimaPro 33 is a 3-phase double-conversion online UPS using PWM transformer-less technology, DSP-controlled technology, APFC in all phases, and ATS function for a high performing, reliable UPS for comprehensive power protection, performance, and efficiency. Enhanced features such as APFC, MBS, dual input power sources, and parallel-redundancy flexibility offers even greater reliance in power source and seamless operation. The APFC feature monitors input voltage for leading or lagging to correct as needed to ensure all phases are balanced to maintain high power efficiency and prevent harmonic currents from distortion so mission-critical equipment, especially sensitive equipment, receive higher quality power for optimal equipment performance. Customizable features such as adjustable charging current, frequency converter, ECO Mode, and others make this the ideal solution for organizations demanding the highest level of power quality and reliability.

Main Features

True Online Double-Conversion Topology

True online double-conversion topology for constant, clean power supply for connected equipment with output power isolated from common input power quality issues. Zero transfer time ensures seamless, uninterrupted operation when a power disruption occurs.

High Overload Threshold

Keeps the UPS running in Line Mode when overloaded for a period time. This series will keep running in Line Mode up to 60 minutes at 110% overload capacity and up to 1 minute at 130% overload capacity.

DSP Controlled Technology

DSP (digital signal processor) controlled technology for high reliability, accuracy, and efficiency.

APFC in all Phases

APFC (active power factor correction) improves the power factor and power quality by reducing the load on the electrical system while improving energy efficiency and reducing power loss. By having APFC in all phases, the UPS is able to deliver reliable power protection.

Maintenance Bypass Switch (MBS)

Safely service the UPS while keeping connected equipment powered for zero downtime with the built-in MBS.

1A to 12A Adjustable Battery Charger

Adjust the battery charger based on the number of batteries in the UPS for faster recharge times.

EMI / RFI Filter

EMI / RFI filter suppresses electromagnetic noise and radio frequency interference transmitted from AC power.

Emergency Power Off (EPO)

Tab Instantly shut off the UPS and prevent the UPS from supplying power in the event of an emergency.

Dual Input

Hardwire the primary input power with Mains Input and secondary power source to Bypass Input for redundant power supply. If connected to an ATS, the Main Input will switch over to battery power while the secondary power source starts up if the Mains Input power fails or UPS is damaged. Once the secondary power source (usually generator) starts up to power the UPS, the UPS will run on generator power until the main power supply returns. If for some reason the secondary power does not start up, connected equipment will continue to run on battery power.

NOTE: Requires ATS (automatic transfer switch) for the UPS to automatically switch between the two input power sources.

Transformerless Design

Transformer-free design uses advanced electronic components to perform power conversion, voltage regulation, and power conditioning instead of a transformer. Some of the advantages include high efficiency (particularly at lower loads), lower noise level, reduced heat generation, improved reliability, reduced harmonic distortion, smaller footprint and weight, enhanced scalability, and lower total cost of ownership.

Generator Compatible

This UPS is compatible with inverter generators using electronic governors. Inverter generators produce pure sine wave for better performance and "cleaner" power. Electronic governors uses an electronic control system that detects changes in the load and can adjust the throttle to control the engine and generator control functions for output power that is reliable and constant under variable loads.

Compact Design

Space-saving design with high performance capabilities with flexibility to expand in size as business needs increase.

N+X or N Parallel Option (up to 6)

This series allows for the expansion of the UPS reliance with a parallel-redundant setup up to 6 units (N+X) or a parallel-capacity system (N) to increase overall capacity.

Smart Battery Management

Maximize battery performance and lifespan with an intelligent, 3-stage battery charging system to auto-sense the optimal battery charging performance based on battery levels. Charging will be either constant current, constant voltage, or floating for optimal battery performance.

Cold Start Capable

Turn on the UPS even without utility power as long as there is sufficient battery power.

5-inch Touchscreen LCD

Colorful, easy-to-read LCD screen shows real-time status information of your UPS power conditions including the voltages, capacity level, battery level, faults, event logs, settings, and more.

Intelligent Slot

For use with a network management card to remotely monitor and control the UPS from a web browser.

Power Management

Software Monitor and control the UPS from your computer with the included user-friendly software to automate computer shutdown, monitor battery levels, set UPS parameters, receive alerts of abnormalities, and more.

Optional Accessories (Not Included)

• Network Management Card - For remote power monitoring. See model number #SNMP3-2 for compatibility with this UPS series.
• Parallel Cable - Parallel up to 6 x ULT-P20K33HV for parallel redundancy. 1 x parallel cable required per UPS set.
