• Is the HV a standby UPS?
  • No. The HV uses a seamless ferroresonant transfer system to secure optimum performance. Unlike standby systems that do nothing until power fails, the HV conditions, regulates, and filters the power 100% of the time. The load receives a steady, spike-free, sine wave voltage regardless if the incoming power is in or out of acceptable range.
• How does the HV regulate voltage?
  • The HV incorporates a highly efficient ferroresonant transformer that produces a steady output voltage over a wide range of input voltages. Even in severe brownout conditions, the HV delivers regulated voltage to within +/-3% without using battery power.
• How does the HV correct for bad power?
  • The ferroresonant transformer remains in the power circuit 100% of the time. Since the transformer is designed to pass only 60Hz, the power distortion of other frequencies will not be present in the output. The HV corrects for bad input voltage waveforms with distortion levels as high as 40%. Most standby UPS units will not tolerate over 7% distortion, so they switch to battery backup. The HV preserves the battery power for only outages.
• What level of TVSS (surge) protection is offered by the HV?
  • The limited protection that a standby UPS offers is from its TVSS circuit. The typical TVSS protection is no more than a couple of dime- to nickel-sized metal oxide varistors (MOVs), offering limited and temporary protection. In contrast, the HV protects the load with 180 pounds or better of pure transformer steel. The transformer absorbs the high energy transients, leaving the load solidly protected. In addition, it also replenishes the energy where notching and reverse spiking occur.
• Is it true that the HV improves the operation of equipment connected to it?
  • 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.
• How does the HV correct for ground noise when other UPS models of similar VA sizes do not?
  • The HV uses 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 models use an auto transformer for some voltage correction functions and ignore the need for common mode noise attenuation.
• How does the HV correct for improper site wiring?
  • Site wiring is always unknown. There may be voltage variations, ground current that causes disruptive operation (unsolvable with TVSS), mixed grounds, etc. The HV’s ferroresonant 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. The new ground assures the data spike attenuation networks are at the most optimal location (the shortest lead length to ground).
• How does the HV provide superior isolation compared to typical units of the same size?
  • Most standby UPS just pass the incoming power directly to the load without any regulation, power conditioning, and/or isolation. The HV uses a special ferroresonant isolation transformer for power purification and isolation.
• Does the HV do anything to correct for load generated harmonics?
  • Yes. The HV’s ferroresonant transformer acts as a band pass filter, allowing only 60 cycles to pass. Load generated noise and harmonics are trapped in the output of the HV, preventing the unwanted harmonics from reaching the input power source. Standby uninterruptible power systems simply don’t do anything for harmonics; you live with the results.

Controlled Power Company warrants the HV Series Uninterruptible Power Systems to be free from defects in material and workmanship for a period of one (1) year following shipment from the factory. Batteries are warranted with a one (1) year full replacement warranty, and an optional four (4) year pro-rate with applicable maintenance contract. Controlled Power Company agrees to replace, F.O.B. its factory, any parts which fault through defect in material or workmanship during the warranty period.

Warranty begins from date of shipment unless a factory start-up is purchased, then the warranty begins from date of start-up or 90 days from ship date; whichever comes first.

Consult the factory for additional warranty details, and a description of start-up services provided.
