DESCRIPTION
The TEC5V4A-NT is an electronic module designed for
driving TECs (Thermo-Electric Coolers) with high stability in
regulating the object temperature, high energy efficiency, zero
EMI, and small package. Figure 1 is the photo of an actual
TEC5V4A-NT.
The module provides interface components for users to
configure desired object temperature range, i.e. set-point
temperature range; maximum voltage across TEC, i.e.
maximum TEC voltage; and the compensation network. The
compensation network compensates the high order thermal
load and thus stabilizes the temperature control loop.
It provides these functions: thermistor T-R curve linearization,
temperature measurement and monitoring, temperature
control loop status indication, TEC voltage monitoring, power
up delay, and shut down.
The TEC5V4A-NT comes with a high stability low noise
3.0V voltage reference which can be used for setting the
desired object temperature by using a POT (Potentiometer) or
a DAC (Digital to Analog Converter). When using this
reference for setting the set-point temperature, the set-point
temperature error is independent of this reference voltage.
This is because the internal temperature measurement network
also uses this voltage as the reference, the errors in setting the
temperature and measuring the temperature cancel with each
other, setting the object temperature with higher stability. This
reference can also be utilized by an ADC (Analog to Digital
Converter), for the same reason, the measurement error will
also be independent of the reference voltage, resulting in a
more accurate measurement.
The TEC5V4A-NT is packaged in a 6 sided metal enclosure,
which blocks EMIs (Electro-Magnetic Interferences) to
prevent the controller and other electronics from interfering
with each other.
