POW-R-BRIK™
Phase Control Modules
345-800 Amperes/400-3000 Volts
Typical Thermistor Circuit
Thermistor temperatures can be
measured using the following
circuit arrangement in conjunction
with a 5 volt source. Resistance
values for R1 and R2 are specified
for two operating temperature
ranges.

Curve matched ±2% over temperature range of +40°C
to +125°C. Resistance tolerance specified at +125°C,
±6%.
Without self heating, 10mW maximum thermistor
dissipation.
Use “Sensor at Tj” ohms from characteristics for
recommended steady state overload trip resistance.
The output signal (V0) is
approximately 30 mv/°C over the
temperature range indicated.
