GENERAL

DESCRIPTION

The PC-3 Ultra is a special purpose UV curing lamp used for small area curing of

adhesives, coatings, and potting materials. It emits a 5 mm diameter spot of UV light

from a liquid light guide. This guide is hand-held for complete mobility or clamped into

position on assembly equipment or work stations for repetitive operations.

The unit consists of a stainless steel housing containing a 50 watt power transformer,

circuit protection, lamp/reflector assembly, internal light filter for extended lightguide life,

cooling fan, light guide mount, lamp status indicator light, non-resetable hour-meter, and

shutter system. Electric shutters are supplied with timed and manual shutter operating

modes. The light guide is separate and plugs into the bezel. Light normally is not

emitted from the unit when the light guide is removed. But the light can escape when

the shutter is activated. That is why it is important to have the liquid guide engaged

within the bezel. Light can be emitted from the unit when the light guide is removed

from the bezel. Lamps are rated at 500 hours of life.

The light source contains circuitry which allows the user to monitor whether the lamp is

operating or not. This circuit will operate with a simple, audible alarm, a visual display,

a PLC or a computer system. The software to monitor via a personal computer (IBM

compatible) is available upon request from Dymax Corporation.

The power supply operates on line voltages of either 115 or 230 Vac, and 50 or 60 Hz

(factory set). AC voltage is stepped down and rectified to DC through a transformer and

fullwave bridge rectifier. A separate high voltage winding on the transformer provides

ignition voltage for the lamps. A blocking diode is located between the power regulator

and the high voltage winding to prevent damage to the regulator circuit. When the lamp

ignites, the high voltage is dissipated across the lamp, although the high voltage

winding is always energized. If the lamp extinguishes due to a momentary power

failure, it will reignite after it cools down if the power switch is left on.

A cooling fan is provided to keep the lamp housing and internal components of the

power supply at the optimum operating temperature. The fan must not be covered or

otherwise blocked. The UV source is a 50 Watt short arc mercury vapor lamp mounted

in a reflector and pre-focused to provide optimum light output. The unit is rated for

continuous operation.
