EH300/EH301 Series Modules can accept energy from many types of electrical energy sources and store this energy to power conventional 3.3V and 5.0V electrical circuits and systems.
The EH300/EH300A/EH301/EH301 series are EPAD® energy‑harvesting modules that accept input voltages from 0 V to ±500 V and store energy to power 3.3 V and 5.0 V circuits. They operate continuously, charging an internal capacitor bank and providing up to 1 A output current when the stored voltage is within the configured thresholds.
These modules are RoHS‑compliant, require no user setup, and are shipped ready to use. They include optional input/output pins for external control and are suitable for intermittent, low‑power monitoring applications across a wide temperature range.
