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

Description The Series 700F front access power conditioning voltage regulator features a small footprint, high efficiency design, and optional power quality monitoring. With a unique front access cabinet design, left, right, and rear access is not required for system installation, operation or service! The Series 700F is an electronic, microprocessor-controlled tap switching power conditioning voltage regulator, which consists of an all-copper, triple-shielded isolation transformer. In conjunction with the electrostatic shields, the low output impedance of the transformer assures computer-grade performance with excellent noise and transient attenuation. For each of the 7 taps per phase, independently controlled inverse parallel electronic switches provide tight voltage regulation to +/- 3%. Digital processing provides fast, accurate regulation within 1 cycle, without over- or under-shoot.

Three Phase Sizes: 10kVA, 15kVA, 25kVA, 30kVA, 50kVA, 75kVA, 100kVA, 125kVA, 150kVA

  • 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.
