DESCRIPTION

PTC5000

±5 A Temperature Controller

PTC10000

±10 A Temperature Controller

PTCEVAL

Evaluation board for PTC-PCB 
Series Controllers

TIME-TESTED RELIABILITY

The PTC Series PCB-Mount Temperature Controllers are 
based on our long-proven PTC-CH linear controllers, and 
deliver the precision performance and reliability you expect 
from Wavelength Electronics. 

PTC Series controllers are found in such diverse 
applications as particle and droplet measurement, 
communications, manufacturing test, and medical systems.

POWERFUL AND EASY TO USE

The PTC controllers operate from a single power supply 
between 5 V and 30 V, and two models drive ±5 A or ±10 A 
to a Peltier thermoelectric cooler or a resistive heater. 
These controllers mount directly to your circuit board.

PTC controllers interface with a variety of temperature 
sensors, and the bias current is adjustable in order to 
maximize controller sensitivity and stability for your 
application.

You can use the PTCEVAL board to quickly con

fi

 gure the 

PTC controller for prototyping. Using the same controller 
for development and production helps guarantee there are 
no surprises when it’s time to integrate the 

fi

 nal design.

FEATURES AND BENEFITS

Temperature Setpoint controls

•  Short term stability of 0.0012°C (off-ambient)
•  Long term stability 0.002°C
•  Selectable sensor bias current
•  Adjustable current limit
•  PI Control with “Smart Integrator”
•  Failsafe Setpoint default in case of remote 

temperature setpoint signal error
