POWER PROCESSOR SERIES 700A - POWER LINE CONDITIONERS

1.0 SCOPE This specification covers the electrical aspects of the Power Processor which provides clean regulated power to computers and other sensitive electronic equipment.

2.0 GENERAL The Power Processor, Power Line Conditioner consists of an all copper, multiple tapped, triple shield isolation transformer. The low output impedance of the transformer in conjunction with the electrostatic shields assures computer grade performance with excellent noise and transient attenuation. Independently controlled inverse parallel electronic switches for each of the 7 taps per phase provide tight regulation. Linear devices are used for line synchronization to prevent phase shift errors normally associated with simple CT zero current crossing acquisition. The microprocessor control accurately selects the correct tap to maintain the output typically at 2.5% of nominal, correcting for voltage disturbances within one cycle. Digital processing provides fast and accurate regulation without over or undershoot.

3.0 DYNAMIC ELECTRICAL CHARACTERISTICS

3.1 LINE VOLTAGE REGULATION Input Line Voltage +10%, -25% Output Line Voltage +2.5% typical (+3% maximum). Optional Extended Range for Intermittent Duty only: Input Line Voltage +10%, -40% Output Line Voltage +5.5% typical (+6% maximum).

3.2 RESPONSE TIME Response time is less than 1/2 cycle.

3.3 CORRECTION TIME The output voltage is corrected within 1 cycle.

3.4 LOAD REGULATION The output is maintained to within 2 1/2% of nominal or less, from no load to full load.

3.5 OPERATING FREQUENCY 60 Hertz + 3 Hertz

3.6 HARMONIC DISTORTION Less than 1% THD added to the output waveform under any dynamic linear loading conditions presented to the line regulator.

3.7 TURN-ON CHARACTERISTICS When energized the voltage overshoot is 5% or less of the nominal voltage for less than 1 cycle.

3.8 OVERLOAD RATING 200% for ten seconds. 1000% for one cycle.

3.9 NOISE ATTENUATION

3.9.1 Common mode noise attenuation is typically 140 dB or greater.

3.9.2 Transverse mode noise attenuation is 3 dB down at 1000 Hertz, 40 dB down per decade to below 50 dB with a resistive load.

3.10 AUDIBLE NOISE 40dB to 50dB measured 3 feet away, depending on size.

3.11 EFFICIENCY 97% Typical.

4.0 MAIN TRANSFORMER

4.1 BASIC CONSTRUCTION The transformer windings are of all copper conductor construction with separate primary and secondary isolated windings.

4.2 MAGNETIC Grain oriented, M6 grade, stress relieved silicon transformer steel is utilized to minimize losses and provide maximum efficiency. Flux density will not exceed 15k gauss.

4.3 INSULATION Class N (200° C) insulation is utilized throughout.

4.4 SHIELDING The transformer has multiple (three) copper shields to minimize inner winding capacitance, transient and noise coupling between primary and secondary windings. Inner winding capacitance is limited to .001 pf or less.

4.5 COOLING The transformer is designed for natural convection cooling.

5.0 MAIN INPUT BREAKER A main input molded case thermal magnetic circuit breaker, rated at 125 % of the full load input current, is furnished as an integral part of the unit.

6.0 BY-PASS SWITCH (OPTIONAL) A rotary bypass switch is provided which will bypass the regulator portion of the Power Processor. The regulator can be either on-line or bypassed with one turn of the switch.

7.0 MONITORING (Three phase units only)

7.1 ALERT LIGHT An indicator Light is provided to indicate that the output has been disabled by one of the following conditions: Transformer over-temperature Over voltage SCR thermal overload Under voltage

8.0 CABINET (Salient Characteristics)

8.1 Termination - Termination is rear access with input and output connections made of copper stand off bus.

8.2 Ventilation - Ventilation originates from the bottom of the cabinet and exhausts at the rear of the cabinet.

8.3 Mobility - The Power Processor cabinets are equipped with fixed casters located so as not to exceed 600 lbs/sq inch on any one caster.

8.4 Accessibility - The cabinet is constructed with lift off side panels for ease of access.

9.0 CONTROLS

The control portion of the cabinet containing the circuit boards and connection to the semi- conductor devices is separate from the transformer and input / output termination.
