Series 700F Front-Access Power Processor (10 kVA - 150 kVA) Three Phase
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%, and optional power quality monitoring. Digital processing provides fast, accurate regulation within one 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 each of our models are offered with an optional seismic rating. Seismic-rated Series 700F models are available with an input nominal voltage of 208VAC, 240VAC, or 480VAC and are provided on floor-mounting channels. These models meet 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.

Frequently Asked Questions
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 provide clean power, free of voltage spikes, transients, and electrical noise.
Are all tap switching power conditioners the same?
No. Some systems use six voltage taps per phase, while the Series 700F uses seven 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 ensure 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.
Where should the Series 700F tap switching technology be used?
Tap switching technology should be used for applications and with 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 one cycle. Other voltage regulating technologies can take numerous cycles or seconds to adjust. This is not acceptable for most electronically controlled systems.
What power quality advantages does the Series 700F offer?

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 three phase loads, including motor loads. The Series 700F protects downstream equipment by electronically shutting off if the power source feeding it loses one or more phases. Once the phases return, the Series 700F will turn all three phases back on simultaneously. This protects the load and ensures that the line currents will not exceed critical values.
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.rnrnConservatively 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.
