Each pack supplies power to a discrete module of unicells with
a dedicated, externally mounted indicator light that illuminates to
indicate normal operation. The PSG power pack meets UL safety
standards. In the event of a short circuit or overload condition to the
output side, the power pack’s high voltage collapses and the indicator
light is in the flashing mode. Upon removal of the overload, the power
pack automatically returns to normal and the indicator light will be
illuminated. The power pack is self-protecting against overloads (e.g.
dirty components, short circuits in ionizer and cell circuits) and is self
regulating when the AC voltage supply varies from 90 to 132 VAC.
1.4.2 Unicell Ionizer Section
Each unicell supports ten (10) 10 mil tungsten steel ionizer wires
spring mounted and centered between aluminum ground plates.
Refer to Figure 6. When high DC voltage is applied to the wires, a
powerful field charges contaminated particles. Ionizer standoff con-
voluted insulators are part of the ionizer wire support bar(s) which
separates high voltage from grounded chassis.
1.4.3 Unicell Collector Cell Section
Each unicell contains a series of parallel plates, alternately charged
and grounded, whose planes are in-line with the direction of airflow.
Refer to Figure 6. Charged plates are connected electrically and sus-
pended from four triangular shaped insulators on each end of the
unicell. The ground plates are independently supported.
