Reliability of Switchmode Power Conversion Versus Legacy Technologies

MicroGenius 2 offers even better field reliability than the already super-reliable NRG. Operating at high frequency, switchmode power converters outperform line frequency (50 or 60 Hz) power conversion topologies such as SCR and controlled ferroresonant in nearly every way. Switchmode technology delivers advantages in dynamic response, smoothness of DC output, size, weight, noise, energy efficiency, cost, Read More

Commissioning NiCd Batteries with MicroGenius 2, S2, S4

Application Note 26 – click here to download as .pdf Introduction This application note describes how to commission discharged (zero charge) Nickel-Cadmium batteries using the MicroGenius 2 or MicroGenius S2/S4 chargers. Nickel-Cadmium (NiCd) batteries can be supplied already charged or in a discharged state. Verify your NiCd battery type to determine if commissioning is required. Read More

Industrial Switch Mode Power – Small, Light and Rugged

Switch mode power conversion technology offers many benefits not available with line-frequency converters such as those employing SCR technology: small size, light weight, high efficiency, modularity, and very clean DC power. But, most switch mode power supplies and chargers were not designed for the rigors inherent to industrial environments such as dirty air, electrical transients, Read More

Verifying / Changing the Voltage Range of MicroGenius 2 Chargers

This tech tip describes how to verify the factory-set voltage range of a MicroGenius 2 battery charger and change it if necessary.   All MicroGenius 2 chargers are electronically programmed at the factory for either 12v or 24V application based on the customer order. To verify the voltage for which a particular charger is set, remove Read More

All About Sizing Chargers for Engine-Starting Batteries

What is the correct output ampere rating of a battery charger used in engine-starting applications? Let start with an example. The prime mover for a medium size generator set, in this example 500 KW electrical output, would be powered by an engine of about 15 liter displacement. The starter motor of an engine this size Read More
