Theory of Operation Teledyne API – Model T300/T300M CO Analyzer
Teledyne Analytical Instruments 310
13.4.7. POWER SUPPLY/ CIRCUIT BREAKER
The analyzer operates on 100 VAC, 115 VAC or 230 VAC power at either 50Hz or
60Hz. Individual units are set up at the factory to accept any combination of these five
attributes. As illustrated in Figure 13-14, power enters the analyzer through a standard
IEC 320 power receptacle located on the rear panel of the instrument. From there it is
routed through the ON/OFF Switch located in the lower right corner of the Front Panel.
A 6.75 Amp circuit breaker is built into the ON/OFF Switch.
The bench and GFC Wheel heaters as well as the GFC Wheel receive AC power via the
relay board.
AC Line power is converted stepped down and converted to DC power by two DC
power supplies. One supplies +12 VDC, for valves and the IR source, while a second
supply provides +5 VDC and ±15 VDC for logic and analog circuitry. All DC voltages
are distributed via the relay board.
CAUTION
GENERAL SAFETY HAZARD
Should the AC power circuit breaker trip, investigate and correct the condition causing
this situation before turning the analyzer back on.
