  • Flywheel adaptable


The Q-LS 10-60 Series UPS systems provide superior power conditioning and uninterruptible power for critical high-power applications. The Q-LS provides five stages of isolation and conditioning for a pure, high-resolution sine-wave output signal.

Q-LS 10-60 High-Resolution Sine Wave Output

The Q-LS 10-60 assures consistent power to connected equipment. The systems isolate, filter, and regulate impure and erratic input power to provide a pure and consistent sine wave output.

Branch Circuit Input Protection

The Q-LS has an independent branch circuit for each input loop. In the event that a breaker trips or a short circuit condition occurs on one of the input loops, the other input loops will continue to function normally, avoiding a total system shutdown.

True Galvanic Isolation

The Q-LS incorporates true galvanic isolation on the output, which isolates the AC output under every mode of operation. The Q-LS can accept a different ground between input and output, thus stopping any current leakage through the ground. True galvanic isolation reduces the common mode noise that is normally transferred to the output from the AC power input source.

EMI Suppression

The Q-LS provides EMI (Electromagnetic Interference) filtering, eliminating noise that could interfere with the equipment attached to the UPS system as well as surrounding equipment. The Q-LS Series meets all international EMC (Electromagnetic compatibility) requirements.


  • Variable input & output power configurations (60 Hz, 50 Hz, 400 Hz)
  • Single- and three-phase configurations
  • Active or redundant power configurations
  • Power Distribution Units (PDUs)
  • Inline voltage and frequency converters
  • Twelve-pulse rectifier available in 10-60 kVA (standard in larger systems)
  • Parallel and serial emergency power OFF (EPO)

Harsh Environment Tolerance

Each component used in the Q-LS Series has been selected for exceptional durability and safety. The Q-LS Series can run efficiently in extreme environments: temperature, humidity, altitude, shock, and contamination.

Multi-CPU Design

The Q-LS provides redundancy of all critical functions by utilizing several CPUs on the control board. If one of the CPUs fails, the other CPUs will continue to operate so that output power is not affected.

Hot-Swappable Battery Modules

In order to minimize system downtime, battery modules can be swapped and serviced while the system is running.

Intelligent Battery Charger

The Q-LS Series battery charger features user-selectable charging levels (Low/Med/Hi), depending on the Ah of the battery. The Q-LS system will automatically boost the charge to the battery as needed. This boost charge allows the batteries to charge at a quicker rate and keeps them in their best condition. To avoid overcharging the battery, the boost charge will stop when the ambient temperature is over 35°C (95°F).

Automatic Battery Test

The Q-LS will automatically test the batteries after every boost charge. This test is initiated by a battery discharge or after one month has elapsed since the last test. The Q-LS system will notify the user of the battery’s condition and will indicate when any of the batteries need to be replaced. This feature allows the batteries to be replaced before they fail.

Phase Control Technology

The Q-LS utilizes phase control technology to regulate the DC bus voltage. This feature provides efficient and direct battery charging.

Cold Start Function

The Q-LS can be started independently of an AC power source by using its batteries. Special current-limiting circuitry protects the Q-LS Series from high inrush currents associated with DC battery connections on a dry DC bus. Ordinary online UPS solutions will suffer damage to battery fuses and DC capacitors when batteries are connected to an empty DC bus for cold start applications.
