The EH4205 is designed primarily for driving loads such as theALD EH300/EH301 Series Energy Harvesting Modules. The ACoutputs of the EH4205 are connected directly to the input terminalsof the EH300/EH301 Series Energy Harvesting Modules with atwo-wire cable. They can also be used for trickle-charge applica-tions such as battery charger or super-cap charger, includingsituations where the energy input is not well controlled or regu-lated. For certain applications, the EH4205 can also be usedwithout the EH300/EH301 Series Energy Harvesting Modules.

 Its applications are as below: 

APPLICATIONS

• Charge EH300/EH301/EH300A/EH301A series

EH Modules from low voltage sources

• Energy Harvesting from low-voltage micro-power

energy-generating sources

• Direct or Indirect remote-node power supplies for

Wireless Sensor Networks

• Low duty-cycle metering, control and sensing networks

• Energy capture from Intermittent energy sources

• Trickle-charger for Standby backup power such as

battery-packs or super-capacitor networks

• Backup power for switching between different power

sources

• Industrial and Business systems with always-charged

temporary backup power supplies

• Micro-power Self-boosting oscillator

• Low DC Voltage Booster to supply operating voltage

for another Step-up DC-DC converter

• Extreme life-span power sources

• EH energy capture, storage, and power management

from mechanical, thermal, chemical, solar, biological,

and human body sources

• EH based battery substitution and/or remote battery

charging systems

• Hybrid or alternative power source conditioning

• Condition-based monitoring systems

• Self-powered remote control switching systems

• Hybrid power (dual power) systems with extended

operating lives

• System power reliability enhancement

• Intermittent duty cycle remote site applications
