marlow industries, inc. Subsidiary of II-VI INCORPORATED TECHNICAL DATA SHEET Preliminary EHA-LXXAN1-R02-L1 Thermal Energy Harvesting Demo Unit Water to Air TYPICAL PERFORMANCE VALUES 5.5 ORDERING OPTIONS Model Number Description For pipe diameter 9.5mm[.375”] For pipe diameter 12.7mm[0.5”] TYPICAL PERFORMANCE CURVES Marlow’s EH series offers a range of source-to-application, thermoelectric-based energy harvesting systems for evaluation and testing. Each system integrates a Marlow electrically-matched, thermally- optimized custom thermoelectric generator and heat sink with a Linear Technology LTC series voltage step-up converter to provide the customer with tools and flexibility necessary to evaluate a wide range of test conditions. The EHA-LXXAN1-R02-L1 is designed to harvest power from the temperature difference between a warm fluid stram and the surrounding ambient air.

Model Number MECHANICAL DRAWING Ideal Orientation Good Orientation INSTALLATION: Assembly should be mounted to hot fluid line using the provided mounting brackets and M 3 bolts with a maximum torque of 5.0 in-lbs. A layer of graphite has been adhered to the pipe mounting surface on the EHALXXAN1-R02-L1 to ensure a good thermal contact between the mounting pipe and the EHA assembly. Performance will vary greatly with ambient conditions. For best results, insulate the fluid line feeding into the assembly and mount assembly in ideal orientation as shown. During installation, observe...

VSTORE (PIN 6) Output for the storage capacitor or battery. The VSTORE output can be used to charge a large storage capacitor or rechargeable battery. The storage element on VSTORE can be used to power the system in the event that the input source is lost or is unable to provide the current demanded by VOUT and VLDO output. A large capacitor may be connected from this pin to GND for powering the system in the event the input voltage is lost. It will be charged up to 5.25V. Note that it may take a long time to charge a larger capacitor, depending on the input energy available and the loading...

where IQ is the sleep current on VOUT required by the external circuitry in between bursts (including cap leakage), IBURST is the total load current during the burst, t is the time duration of the burst and T is the period of the transmit burst rate (essentially the time between bursts). CUSTOMER ADDITION SET-UP TIPS VOUT and VSTORE Capacitor For pulsed load applications, the VOUT capacitor should be sized to provide the necessary current when the load is pulsed on. The capacitor value required will be dictated by the load current, the duration of the load pulse, and the amount of voltage...
