Series 700A Power Processor (10 kVA - 1 MVA ) Three Phase
The Series 700A Power Processor is a microprocessor-controlled, electronic tap-switching voltage regulator and power conditioner engineered for precision and reliability. Featuring an all-copper, triple-shielded isolation transformer with seven taps per phase, it delivers ±3% output regulation within one cycle—without overshoot or undershoot. Its low output impedance ensures excellent load regulation and compatibility with dynamic, high-surge loads, while triple electrostatic shielding provides superior noise attenuation and spike suppression. With high efficiency, extended input range options, and optional bypass, metering, and monitoring, the 700A is ideal for mission-critical commercial and industrial applications.

FAQs
What is a tap switching power line conditioner?
u003cdiv class=u0022slide js-acc-hiddenu0022u003ernu003cdiv class=u0022under-accordion-textu0022u003eu003cspan style=u0022letter-spacing: 0em;u0022u003eTap 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.
Where should the Series 700A 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 700A 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.
How much overload can the Series 700A handle?
The Series 700A is very robust and conservatively designed, handling 1,000% of its continuous rating for one cycle and 200% for 10 seconds!
Is the Series 700A 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.
Are all tap switching power conditioners the same?
No. Some systems use six voltage taps per phase, while the Series 700A 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 700A’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.
What power quality advantages does the Series 700A offer?
The Series 700A has three major advantages.rnu003colu003ern tu003cli style=u0022list-style-type: none;u0022u003ernu003colu003ern tu003cliu003eWhen the input voltage rises dangerously above nominal, the microprocessor immediately calculates the correction necessary, and switches to the appropriate voltage compensating tap within one cycle.u003c/liu003ern tu003cliu003eTo 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 three electrostatic shields that provide a high level of common mode noise attenuation, eliminating ground noise and transients.u003c/liu003ern tu003cliu003eSize, weight, audible noise, and operational efficiency are all optimized.
How does the Series 700A 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 700A protects downstream equipment by electronically shutting off if the power source feeding it loses one or more phases. Once the phases return, the Series 700A will turn all three phases back on simultaneously. This protects the load and ensures that the line currents will not exceed critical values.
