These models were designed to conform to IEC 601-
1 requirements,
Nominal Power Consumption
500 watts at maximum % power setting.
Heater Output
440 watts + 5% at maximum %power setting.
Average Energy at Mattress Level is 35 mw/cm2 at
Maximum % power setting
Recommended Bed Level (Model 3000)
27 inches + 2inches from the bottom of heater mod-
ule.
CAUTION: For the Model 3000 Infant Warmer Sys-
tem the height of the bed should be 27 inches + 2
inches from the bottom of the heater module for
proper heating and temperature control.
Line Voltage Compensation
Input voltage is monitored and the heat output is
adjusted to compensate for variations of line vol-
tage.
Circuit Breaker
Rated Current: 7 Amps
Trip Point: 9.45 Amps Minimum
Type: Manual Resetting
Model: Airpax Snapak
Chassis Leakage Current
Less than 8 microamperes on 100v and 120v units
(18 microamperes on 220v and 240v units) measured
at the patient probe connection.
Less than 90 microamperes on 100v and 120v units
{180 microamperes on 220v and 240v units) mea-
sured at an exposed metal surface.
2.2 Controller
Electronics
Microprocessor based control system. Self test func-
tions are performed at power up and during normal
operation.
Power Control Method
Proportional heat control with zero voltage switch-
ing to minimize radiated and conducted EMI.
Examination Light
Nominai illuminance output: 100 foot candles at
center of mattress.
Estimated lamp life: 3,000 hours
Temperature Sensing System
Probe Model Number: LA003
Range: 22-42 degrees C
Accuracy: + 0.3 degrees C
Resolution: + 0.1 degrees C
Probe interchangeability: + 0.1 degrees C
Elapsed Timer
60 minute elapsed timer with hold mode and Apgar
tones.
Manual Mode
Manual mode heat selector range: 0 to 440 watts in
20 increments (5% per step).
Servo Mode
Servo control range 36.0 to 37.5 degrees C in incre-
ments of 0.1 degrees C.
2.3 Alarms
Multiple audio tones
1. Operator prompt tone
2. Alternating single tone
3. Alternating two tone
Overhead Alarm Light 一 一
Large alarm light located on the front of the heater
assembly for easy visual identification.
Probe Failure Alarm
Activates when the skin temperature probe fails
electrically open or short, or is disconnected from
the warmer. The alarm is only active in the servo
mode. The heater is tumed off and the patient tem-
perature display flashes HH.H when this alarm con-
dition exists.
