General Theory Of Operation - Cuda surgical Elite 300 Manual De Servicio

The Elite 300 Illuminator general operation is as follows. Please consult Fig. 1
for wiring information.
The Elite 300 Illuminators are based around a universal input power supply.
Input line voltages of 100-120V ˜ and 220-240V ˜ at 50/60 Hz are applied at the
Power Input Model via a Hospital grade power cord. The input power is then
filtered by a low leakage current EMI Filter. Over-current protection is provided
by two 7.5 amp circuit breakers. A double-pole interlock switch provides operator
safety, which is located on the back left side of the lamp heat shield.
DC power for the other system components is generated by the lamp power
supply. In addition to the 15 volts DC lamp power, it generates +12 VDC. The 12
VDC is used to power cooling fan and the elapsed lamp hour meter.
A rotating stainless steel disc that is placed in front of the lamp controls intensity.
The disc contains holes in varying sizes and patterns. Manual lamp intensity
control is made via a front panel mounted knob.
The lamp used in the Elite 300 illuminators is a 300 watt ceramic arc lamp. For
ignition of the lamp to occur, it takes a high voltage pulse of approximately 20
KV. The power supply generates a pulse of approximately 400-600 volts, which
is then stepped up to the 20 KV pulse by the igniter module circuitry. Connection
to the lamp is made via two jumbo banana jacks.
