Q-LS 180 kVA to 1.6 MVA – Power Management and UPS

Q-LS 180 kV – 1.6 MV
System Benefits

  • Zero in-rush current
  • Lowest input distortion
  • Branch Circuit Input Protection
  • Output phase imbalance protection
  • Smallest footprint and cubic space
  • Unique “whisper-quiet” operation
  • Advanced isolation and conditioning


The Q-LS 180-1.6M Series UPS systems provide superior power conditioning and uninterruptible power for critical high-power applications. The Q-LS UPS provides five stages of isolation and conditioning for a pure, high-resolution sine-wave output signal. It is designed to be connected to one or more battery modules to provide uninterruptible power output during input power fluctuations or failures.

Q-LS 180-1.6M High-Resolution Sine Wave Output

The Q-LS 180-1.6M assures perfect power to connected equipment. The systems isolate, filter, and regulate impure and erratic input power to provide a pure and consistent sine wave output.

Self-diagnosing, Plug-and-Play Modular Design

For ease in troubleshooting, all critical components in the Q-LS system self-diagnose. Plug-and-play modules of high-stress, high-voltage switching electronics make serviceability virtually effortless. Circuit trays can be replaced in a matter of minutes. Tray components can be serviced and put back into use while the system is running.

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.

EMI Suppression

The Q-LS provides EMI (Electro-magnetic Interference) filtering. EMI filtering eliminates 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 (Electro-magnetic compatibility) requirements.

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.

UPS Technology Features

  • Offers multiple voltage options. Input voltages can be different from output voltages.
  • Eliminates the need for independent input/output step-down or step-up transformers.
  • Input: Provides international compatibility for global applications.
  • Output: Allows for multiple and simultaneous output voltages.

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 battery 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.
