DATE 03-01-2006
This MAJ43VV specification covers input voltages from +5 VDC to +28 VDC. The VV-
- in the part number specifies the nominal operating voltage. If the voltage is less than +10 VDC, use a leading zero (i.e. for +5 VDC use VV = 05). The TT in this specification describes set point temperature in °C (i.e. for +75°C use TT = 75).
- - See the TABLE at the end of this specification for available voltages.
1. TEMPERATURE
1.1. Set point
+TT °C (Customer adjustable)
(+35°C to +95°C)
(Set by an external resistor between the "TEMPERATURE ADJUST" Pin and the "0 VDC" Pin. See the TABLE at the end of this specification for resistor value to set the temperature.)
(Use metal film resistors to prevent aging of the set point temperature.)
1.2. Initial tolerance
< ±5°C @ +25°C
2. STABILITY 2.1. Ambient 2.2. Voltage 2.3. Warm-up
±3°C from -30°C to (TT-10)°C ±0.5°C/±10% change ±1°C in 2 minutes @ +25°C (Referenced to temperature at 15 minutes)
3. INPUT POWER
3.1. Voltage
VV VDC (Customer specified)
(+5 VDC to +28 VDC)
3.2. Voltage tolerance
±10%
3.3. Power a. At turn on
< 6 Watts @ +25°C b. Slope
- -0.024 Watts/°C typical
To calculate the typical steady state power (Pss), use the following formula.
Pss = (TT
- ambient temperature of unit)°C x 0.024 (Watts)
