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.
