The HTC Series Temperature Controller is a linear
controller designed for stable, low noise operation.
We recommend using a regulated, linear supply
for optimum performance. Depending on your
requirements, you may be able to use a switching
power supply. [A switching power supply will affect
noise and stability.]
The recommended operating voltage is b5 V
and +12 V. The voltage available to the thermoelectric
is the “Compliance Voltage.” Compliance voltage
varies with the input voltage.
A heatsink is required to properly dissipate heat from
the HTC mounting surface. Maximum internal power
dissipation is 17 Watts.
Special attention to grounding will ensure safe operation.
Some manufacturers package devices with one lead
of the sensor or thermoelectric connected to the metal
enclosure or in the case of laser diodes, the laser
anode or cathode.
WARNING: Precautions should be taken not to
earth ground pins 11, 12, or 13. If any of these pins
are earth grounded, then pins 5, 10, and 14 must be
floating with respect to earth ground.
