The DBTEC-2A is designed to control thermoelectric coolers to a high precision, especially in diode lasers. It maintains temperature regulation using an adjustable sensor bias current and error amplifier circuit that operates with thermistors, RTD’s, AD590 and LM335 type temperature sensors. The DBTEC-2A can supply up to 2 Amps of heat and cool current to the thermoelectric from a single power supply.

Two heat sinking options are available for the driver. The first option allows you to mount the TEC driver directly to your instrument chassis or other large heat sink. The second option uses a small, efficient heat sink mounted on the TEC driver. For added thermal dissipation, an optional small fan can be mounted on the driver or your instrument fan can be used. A twenty turn potentiometer is used to set the temperature or you can use a remote potentiometer or voltage source. Adjustable potentiometers are also available to set the high and low current limits. A dipswitch allows the sensor bias current and sensor gain to be optimized for your sensor type. Monitoring pins are available for temperature set point and actual temperature. Resistive heaters can be used by disabling the cooling current output.

Our line of diode lasers that are compatible are the Lepton IV-TE OEM Series (circular beams) and SRT-F OEM Series (Fiber coupled lasers).
