Same Sky SPG Thermoelectric Generator – Same Sky® and its Thermal Management Group today announced the expansion of its thermoelectric generator (TEG) modules product line. Utilizing the temperature difference between the hot and cold side of the module to generate usable power, the SPG family of thermoelectric generators now offers output power up to 27.3 W in expanded package sizes from 30 x 30 mm to 80 x 80 mm with profiles as low as 3.5 mm. They are ideally used in applications where waste heat is present, like industrial processes, to recover energy that would otherwise be lost.
These TEG modules feature silicone sealing, continuous maximum hot side temperatures up to 300°C, and graphite pad options for a simplified thermal interface. Additional specifications measured under conditions (Th = 300°C / Tc = 30°C) include:
- Open circuit voltage: 8 to 17.7 Vdc
- Matched load resistance: 0.83 to 5.7 Ohms
- Matched load output voltage: 4 to 8.8 V
- Matched load output current: 1 to 5.7 A
- Heat flow across module: 90 to 525 W
- Heat flow density: 6.2 to 13.2 W/cm2
The SPG models are available immediately with prices starting at $49.55 per unit at 25 pieces through distribution. Please contact Same Sky for OEM pricing.
