TM2 30-15-2.8 is a two-stage thermoelectric cooler with a ∆Tmax of 95 °C, with a hot-side temperature of 27 °C (105 °C with Th of 50 °C ), delivered to a 15x15mm cold-side. Typically powered by 12 or 15 volt DC power sources TM2 30-15-2.8 provides up to 25 °C more ∆T than is possible with a single-stage module.

With a Qmax of about 9 watts the module is best cooling a no-load ~ low-load sensor or device. At full power, this module has a total heat load of roughly 50 watts to heat-sink from the 30x30mm hot-side. It’s likely a forced convection heat-sink, liquid heat-sink, or cold ambient (i.e. wing-tip CCD) will be required.

In electro-optic and photonic applications, TM2 30-15-2.8 is commonly used to maintain a cold, and constant, temperature in order to stabilize the wavelength detector or sensor.
