Power Processor Series 700F (10kVA - 150kVA)

The Series 700F is a front access, tap switching, power conditioning voltage regulator which features a small footprint, high efficiency design, triple-shielded isolation transformer, tight output voltage regulation to +/- 3%, as well as optional power quality monitoring. Digital processing provides fast, accurate regulation within 1 cycle, without over- or under-shoot. With a unique front access cabinet design, left, right, and rear access are not required for system installation, operation or service.

The Series 700F has been shake-table tested and meets seismic standards which satisfy the California Office of Statewide Health Planning (OSHPD) requirements, as well as CBC 2013, and IBC 2015 standards! The verification testing required is recognized and accepted by most of the U.S., as well as other countries, and not exclusive to the hospital market.

  • What is a tap switching power conditioner?

  • Tap switching describes a voltage regulating system that uses pre-selected transformer taps to compensate for varying line voltages. A microprocessor control selects the correct tap, and makes a connection through high-powered electronic switching devices. This technology is fast, accurate, and very efficient. Power conditioner refers to the system’s ability to provided clean power, free of voltage spikes, transients, and electrical noise.

  • What power quality advantages does the Series 700F tap switching power conditioner offer?

  • Three major advantages: (1) When the input voltage rises dangerously above nominal, the microprocessor immediately calculates the correction necessary, and switches to the appropriate voltage compensating tap within 1 cycle. (2) To provide power conditioning, a low impedance shielded isolation transformer is used to minimize voltage distortion and sags commonly associated with high surge currents. Loads that create momentary surge currents do not affect other equipment connected to the system. The isolation transformer is constructed using 3 electrostatic shields that provide a high level of common mode noise attenuation, eliminating ground noise and spikes. (3) Size, weight, audible noise, and operational efficiency are all optimized.

  • When should the Series 700F tap switching technology be used?

  • Tap switching technology should be used for applications and equipment that require a regulated power source to function properly and perform at an optimum level. For most electronically controlled systems, voltage regulation (correction) must occur within a few cycles. The Series 700F provides voltage correction in 1 cycle. Other voltage regulating technologies can take numerous cycles or seconds to “adjust”. This is not acceptable for most electronically controlled systems.

  • Are all tap switching power conditioners the same?

  • No. Some systems use 6 voltage taps per phase, while the Series 700F uses 7 voltage taps per phase. This extra tap has a big benefit, resulting in tighter voltage regulation and a more stable power source. The Series 700F’s proprietary switching algorithms insure that incoming voltage distortion will not affect regulation performance, and that nuisance switching and voltage over-shoot often seen with other manufacturers’ designs are eliminated.

  • How does the Series 700F protect the load from a utility loss of phase condition?

  • A utility loss of phase condition can prove detrimental to sensitive 3 phase loads, including motor loads. The Series 700F protects down-stream equipment by electronically shutting off if the power source feeding it loses one or more phases. Once the phase(s) return, the Series 700F will turn all 3 phases back on simultaneously. This protects the load, and insures that the line currents will not exceed critical values.

  • How much overload can the Series 700F handle?

  • The Series 700F is very robust and conservatively designed, handling 1000% of its continuous rating for 1 cycle, and 200% for 10 seconds!

  • Is the Series 700F as reliable as other technologies?

  • Yes, and in some cases…much more. Our tap switching technology has a long history of reliability; exceeding 200,000 hours of field compiled data. Conservatively designed, rated components are never stressed. In the event that input or output conditions exceed the unit’s ratings, protective devices are strategically placed to minimize or eliminate component failure.

  • Since OSHPD is pertinent to hospital construction within the state of California...can the seismic-rated Series 700F be used in other states and provinces, and for non-hospital applications?

  • The answer is YES to both questions. The Series 700F has been OSHPD pre-approved and certified via shake-table testing to a very specific set of criteria. Testing and data reporting were completed to the following standard: ICC – AC156: “Acceptance Criteria for Seismic Certification by Shake-Table Testing of Nonstructural Components and Systems”. The important fact to remember, is that this standard satisfies IBC 2015, as well as OSHPD and CBC 2013… this means that the Series 700F models carry verification testing which is recognized and accepted by most of the United States, as well as other countries. We DO receive a number of requests for seismic-rated equipment, outside of the state of California! The Series 700F is the perfect power conditioner for industrial and commercial facilities located in earthquake-prone regions!

  • Are there tangible differences between seismic-rated and traditional (standard, non-seismic) Series 700F models?

  • Yes, but very few. Product model weights and dimensions are the same for both seismic-rated and non-seismic units. However, seismic-rated units are constructed exclusively with floor-mounting channels; and are only available with an input nominal voltage of 208VAC, 240VAC, or 480VAC. While 600VAC and custom voltage models can be designed and built to the same seismic ratings...they have not been OSHPD pre-approved.
