January 23, 2012--Wavelength Electronics.anounces PTC Series PCB-Mount Temperature Controllers, The PTC controllers operate from a single power supply between 5 V and 30 V, and two models drive ±5 amps or ±10 amps to a Peltier thermoelectric cooler or a resistive heater. These controllers mount directly to a 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.
Features include: * Onboard controls, combined with the ability to remotely control the PTC allows maximum application versatility. * Built-in heatsink and fan simplifies thermal management of the controller. * If the remote temperature setpoint signal is lost, the controller defaults to a standard “safe” temperature setpoint (25ºC when a 10 kΩ thermistor is used).
The safe temperature can be changed at the factorys. * An onboard trimpot is used to set the output current limit to prevent over-driving the TEC, and helps protect the load from thermal runaway situations. * Proportional gain is easily adjusted with an onboard trimpot. * Low temperature-coefficient design remains stable across a wide range of ambient conditions.
