DATASHEET AND OPERATING GUIDE
PTCxK-CH Series
Chassis Mount Temperature Controllers
TIME-TESTED RELIABILITY
The PTCxK-CH Series Chassis Mount Temperature
Controllers deliver the precision performance and long-term
reliability you expect from a Wavelength Electronics
temperature controller.
APPLICATIONS
PTCxK-CH Series controllers are found in such diverse
applications as particle and droplet measurement,
manufacturing machine vision systems, biomolecular
interaction analysis, and more.
FEATURES AND BENEFITS
• Drive up to ±2.5, ±5.0, or ±10.0 A of linear bipolar
TEC or heater current
• Add a booster unit to drive up to ±20.0 A
• Single supply operation: 5 to 30 VDC
• Small package: 3.0” x 3.2” x 1.1”
• Use a wide variety of temperature sensors
• Remote Output and Setpoint controls
• Short term stability: 0.0012°C
• Long term stability: 0.002°C
• Selectable sensor bias current
• Adjustable current limit
• Failsafe Setpoint default in case of remote
temperature setpoint signal error
VERSATILE AND EASY TO USE
The PTCxK-CH controllers operate from a single power
supply between 5 V and 30 V. The linear bipolar controller
drives a Peltier thermoelectric cooler or a resistive heater,
and integrates easily into OEM applications.
PTCxK-CH controllers interface with a variety of
temperature sensors, and the bias current is adjustable in
order to maximize controller sensitivity and stability.
The compact chassis mount design simplies heatsinking
and requires minimal space. PTCxK-CH controllers are
quick to congure for your prototype project, and there are
no surprises when it’s time to integrate the controller into
the nal design.

QUICK CONNECT GUIDE
TO ENSURE SAFE OPERATION OF THE PTCXK-CH
! CONTROLLER, IT IS IMPERATIVE THAT YOU VERIFY THAT THE
UNIT WILL BE OPERATING WITHIN THE INTERNAL HEAT
DISSIPATION SAFE OPERATING AREA (SOA).
Visit the Wavelength Electronics website for the most
accurate, up-to-date, and easy to use SOA calculator:

Figure 1 is a top view of the PTCxK-CH, showing the
trimpots and connector identiers. Conguring the PTC for
operation with remote controls, or changing the sensor bias
current, requires the cover be removed; refer to page 9.
Figure 3 is the Quick Connect schematic for TEC operation
using a Negative Temperature Coefcient (NTC) sensor.
Refer to page 7 and page 8 for additional wiring
diagrams.
We recommend using a test load and simulated thermistor
when conguring the PTCxK-CH; see Figure 2. The
thermistor test load simulates a 10 kΩ thermistor operating
at 25ºC ± 5ºC.

! Use caution when the PTC is combined with a PLD laser driver: if the TEC or
thermistor is connected to the laser diode, two power supplies may be required and
must float independently of each other.
