The Ultima RT series is a true double-conversion online UPS with pure sine wave output delivering reliable power protection for mission-critical equipment in rack and tower configuration to fit standard rack cabinets. Power outages, even momentarily ones, cause monetary loss to businesses and operation flow. The zero transfer time from Line to Battery ensures there is no power gap when power goes out and mission-critical equipment rely on the UPS to keep businesses powered. This series features segmented outlet groups to keep prioritize mission-critical loads in the event of a power disturbance outside normal range. A high 0.9 power factor allows for higher load capacity while a wide input voltage range improves the reliability of the UPS. |
Typical Applications Mid-size servers ATMs Lab equipment |
Networking devices Surveillance systems VoIP / PBX systems |
Security systems High performance computers Slot machines |
Main Features (5) Battery-Backed Outlets with Surge Protection These outlets keep critical electronics online during a temporary blackout and offer protection from power surges and voltage spikes. If a blackout occurs or a power disruption beyond the tolerance range is detected, the UPS will switch over to battery power to keep mission-critical equipment powered. True Double-Conversion Online Topology The main supply is fed directly into the UPS and charges batteries within the UPS. The battery power is then converted back to the main power to feed the protected equipment. Zero Transfer Time True online double-conversion topology for zero transfer time from Line Mode to Battery Mode in case of a power disturbance prevents malfunction of mission-critical equipment. Pure Sine Wave Output Best waveform for sensitive electronics. Benefits include: • Smoother waveform • Best for sensitive equipment • Higher quality than a modified sine wave • Maintains voltage at a safe level • Motors run at their intended speed and with less heat • Equipment runs with less noise • IT equipment lasts longer • Low harmonic distortion Microprocessor Controlled System Built-in microprocessor controlled unit (MCU) optimizes the reliability of the UPS system. Emergency Power Off (EPO) Tab Instantly shut off the UPS and prevent the UPS from supplying power in the event of an emergency. Wide Input Voltage Range Minimizes the need to switch over to battery power and frequency of battery charge and recharge cycles by correcting extreme voltage distortion for higher system reliability. EMI / RFI Filter EMI / RFI filter suppresses electromagnetic noise and radio frequency interference transmitted from AC power. Expandable Battery Runtime Add up to 3 external battery banks to extend the battery runtime of your UPS. NOTE: This UPS does not have any batteries inside. An external battery bank is required for battery backup function. Advanced Battery Management Maximize battery performance and lifespan with an intelligent, multi-stage battery charging system to auto-sense the optimal battery charging performance based on battery levels. Set Output Voltage and Frequency (for Battery Mode) The output voltage can be set to 100 / 110 / 115 / 120Vac and the frequency can be set to either 50Hz or 60Hz for better performance with sensitive electronics when the UPS runs on battery power. In Line Mode or ECO Mode, the UPS output voltage and frequency synchronize with the input voltage and frequency. NOTE: Setting the UPS output to 50Hz will derate the UPS capacity by 40%. For this UPS, the capacity will be cut down to 918W maximum output capacity. |
Adjustable 4A or 6A Battery Charger Select 4A or 6A battery charger for faster battery charging time and depending on the number of external battery banks connected to the UPS. Overload Protection Protects the UPS from an overload. If the circuit breaker trips, unplug a few electronics before resetting the circuit breaker and turning your unit back on. ECO and Advanced ECO Modes Efficiency Corrective Optimizer (ECO) improves energy consumption by changing how power flows through the UPS. ECO Mode: Improves energy efficiency of the UPS by setting the UPS to "standby." Input power will bypass voltage to output when the input voltage is within the acceptable range. Power factor correction and the inverter are still active in this mode. Advanced ECO Mode: Improves energy efficiency of the UPS by setting the UPS to "standby." Input power will bypass voltage to output when the input voltage is within the acceptable range. Power factor correction and the inverter are not active in this mode. Cold Start Capable Turn on the UPS even without utility power as long as there is sufficient battery power. Auto-Restart During AC Recovery Once power returns to normal and the battery levels are sufficient, the UPS will automatically restart. 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. LCD Screen See real-time status information of your UPS power conditions including the voltages, battery level, fault detected, and more. Mute Audible Alarm Temporarily mute the audible alarm from your UPS by pressing the Mute button when audible alerts are ongoing. The mute setting is reset once the UPS returns to a normal state for the next time unusual activity is detected. Optional Accessories (Not Included) • Battery Banks - External battery banks to extend the battery runtime. Add up to 3 external battery banks. See model # ULT-3KRTBB. • Network Management Card - For remote power monitoring. See model # SNMP-2 for compatibility with this UPS series. • Rail Kit - Purchase an add-on rail kit to mount this UPS to a rack cabinet. See model # ULT-123RMKIT for compatible rail kit set for this UPS model. Warranty (US & Canada) 2-year equipment warranty, 2-year battery warranty, and 2-year $25,000 connected equipment warranty with product registration.
