Custom design and manufacture of state-of-the-art battery chargers, UPS, and power supplies for
OEMs in a hurry?
This is a microprocessor controlled DC/DC converter which can be used as a solar charge controller for lithium-ion,
Nickel-Cadmium, and Nickel metal hydride batteries. It also has serial communications and is programmable with great
flexibility.
Serial communications allows you to control voltage, current, or power remotely, or to select on-board programs.
Very flexible input
and output voltages available
Can be used as a
solar charge controller for a wide variety of cell counts and battery capacity.
Can use locally to
the battery to boost voltage after a long wire run, for example on POE.
Output voltage can
be higher or lower than the input voltage.
State-of-the-art
charging algorithms available for a variety of battery chemistries and types
Also useful in
other energy harvesting applications since it can be programmed to use whatever power is available, unlike other battery
charging circuits.
Input and output voltage and current sense can be read by the on-board microcontroller. Other A/D and digital input pins are
available to adapt to your needs, for example battery charge termination measurement, capacity testing, battery quality
testing, electrolysis, sensor control, etc.
Form factor and custom features can be designed to OEM requirements.
This product is a platform that can be programmed to meet your system requirements. Typical programming fees are
$500 to $2000 depending on complexity and test requirements.
