FAQ

  • Are the models LT and LTR standby UPS’s?

    • No. Ferroresonant technology is used to eliminate the “break in power” associated with standby designs. In addition, standby systems provide little to no power conditioning, but the LT and LTR models condition, regulate, and filter the power 100% of the time. Healthcare IT systems receive a steady, spike-free, sinewave voltage, regardless of incoming power conditions.



  • How is voltage regulation achieved?

    • The LT and LTR models incorporate a highly-efficient ferroresonant transformer that produces a steady output voltage over a wide range of input voltages. Even in severe brownout conditions, these models deliver regulated voltage to within +/-3% without using battery power.



  • How is voltage distortion removed?

    • The UPS’s ferroresonant transformer remains in the power circuit 100% of the time. Since the transformer is designed to recreate the output waveform at 60Hz or 50 Hz, the voltage distortion of other frequencies will not be present in the output. The UPS corrects for bad input voltage waveforms with distortion levels as high as 40%. Most standby UPS units will not tolerate over 7% distortion, and they switch to battery backup. The LT and LTR preserve the battery power for outages only.



  • What level of TVSS protection is offered?

    • The limited voltage surge protection that a standby system offers is provided by its TVSS circuit. The typical TVSS protection is no more than a couple of "dime" to "nickel-sized" metal oxide varistors (MOV), with limited capability and an unpredictable life expectancy. In contrast, the LT and LTR suppress voltage surges and attenuate transients via a power conditioning isolation transformer. The transformer absorbs the high-energy transients, and eliminates waveform notching and reverse voltage spikes.



  • Do the LT and LTR improve the operation and increase the reliability of the connected equipment?

    • Yes. The output filter circuit removes unwanted frequencies generated by non-linear loads. This characteristic lowers the high load current demand and improves the power factor. The load draws less current and produces much less heat; increasing its efficiency and extending its life.



  • Is ground noise attenuated, and do all UPS's of similar VA size provide this attenuation?

    • The LT and LTR use a high-level isolation, ferroresonant transformer for power conditioning. Only an isolation transformer removes common mode noise (the noise generated on the ground lead). Most other UPS's do not incorporate an isolation transformer. Some models provide a tapped auto-transformer used for limited voltage regulation. They ignore the need for common mode noise attenuation.



  • How do the LT and LTR correct for improper site wiring?

    • Site wiring is typically an unknown. There may be voltage variations, ground current that causes disruptive operation (unsolvable with TVSS), mixed grounds, etc. The UPS’s power purifying isolation transformer generates the equivalent of a new power source dedicated to the load. It creates a new clean ground reference, and establishes a central ground point for all loads.



  • Is anything done to correct for load-generated harmonics?

    • Yes. Load-generated noise and harmonics are suppressed and not allowed to reach the input power source. Standby UPS's simply don't correct for harmonics.
