Electrical Description
The basic wiring of the Model 500 is shown schematically in
Figure 8
.
Dynacalibrators are powered from a benchtop style transformer on the rear
panel. This is a switcher-style supply that allows a range of input voltage and
frequency from 100 to 240 VAC at 50-60 Hz. The power supply steps the voltage
down and regulates the output to 24 VDC. If the cord end type is inappropriate
for your locale, please contact Vici Metronics for a replacement cord.
The main power switch S1 is on the front panel, along with the main fuse F1.
When the main power switch is on, 24 VDC energizes the main power indicator
on the front panel, as well as the fan and stream switching solenoids.
Power to the permeation chamber heater is controlled by switch S2 on the front
panel. There is a separate fuse F2 and indicator for power to the permeation
chamber heater.
