GENERAL DESCRIPTION:
Quickly interface an ultrastable WTC3243
Temperature Controller to your thermoelectric
or resistive heater load without having to
design a printed circuit board. Onboard
switches, jumpers, and trimpots make
operation simple.
Control temperature using thermistors,
100
Platinum RTDs, or linear temperature
sensors such as the LM335 or the AD590.
Adjust temperature using the onboard trimpot
or a remote voltage. Other adjustable
trimpots con
fi
gure heat and cool current
limits, proportional gain, and integrator time
constant. A dipswitch allows the sensor bias
current to be optimized for your sensor type.
High power applications can use the onboard
fan connections to power a WXC303 or
WXC304 (+5 or +12 V) DC fan attached to a
WHS302 heatsink.
