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 15 k 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. Fans are located on the front of the unit.
4.6 OPERATING TEMPERATURE
The system operating range: 0 to 40 degrees C, 32 to 104 degrees Fahrenheit
4.7 OPERATING HUMIDITY
0-95 % relative humidity non-condensing.
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. For example, a 110 Amp breaker will be provided
for 208 VAC input, a 100 Amp breaker will be provided for a 240 VAC input and a 60 Amp breaker will
be provided for a 480 VAC input.
6.0 BY-PASS SWITCH
A manually operated rotary bypass switch provides bypassing of the regulator portion of the Power
Line Conditioner. The regulator can be either on-line or bypassed with one turn of the switch. The
transformer and suppression circuitry remains in the circuit when in the bypass mode. The bypass
switch is located on the front of the unit.
7.0 MONITORING
7.1 ALERT LIGHT
An indicator light shall annunciate that the output has been disabled by one of the following conditions:
(1) Transformer over-temperature
(2) SCR thermal over-temperature
7.2 INDICATING LAMPS
Output ON indicating lamps shall provided for each phase.
