FEATURES
- Compact form factor
- Regulated output voltage
- High waste heat conversion ratio
- Ultra-low voltage converter
- Reliable solid state operation
APPLICATIONS
- Wireless sensors and transmitters
- LED lighting
- Battery charger The WPG-1 is a self-contained thin-film thermoelectric power generator that harvests waste heat and converts it to usable output DC power. Due to its compact size, output power generation and ability to regulate voltage this device is suitable for use in applications to power wireless sensors and wireless sensor networks. One WPG-1 can produce up to 1.5 mW of usable output power and can handle a wide range of load resistances. An ultra-low voltage step-up converter is incorporated to provide usable output power at low temperature differentials, < 20°K. The output power can be regulated to accommodate three voltage set points: 3.3V, 4.1V or 5.0V. Custom design services are available to accommodate alternate heat absorption and heat dissipation mechanisms or output power requirements, however MOQ applies. Heat is absorbed through a flat heat exchanger plate, energy is harvested by the thin-film thermoelectric and heat is exhausted into ambient environment by the pin fin heat sink. Note: Unit of measure is in mm’s
