SES Flexcharge model NC-25A/12 charge controller - 12 volt DC
The following is copyrighted by SES Flexcharge. NC25A Ultra High Efficiency 25 Ampere Solar and Wind System Charging System Controller
The NC25A-(X) is series regulator designed for alternative energy charging systems ranging in size from 0.1A to 25A. It is the ideal regulator for Solar (PV) and Permanent Magnet Generators (Including outboard motors and smaller wind generators). The NC25A also includes the Charge Divert feature. Charge Divert allows you to use the excess charging source energy for other tasks, or for placing a load on permanent magnet charging sources such as wind generators to prevent over speed conditions. The Divert connection is only activated after the charging source is making energy and the batteries are not using the energy (i.e. A wind generator will not be starting into the divert load). This controller can easily and inexpensively be expanded to handle one or more banks of 100A charging sources. (1000A max charging current in this configuration). Multiple battery banks can be charged with the use of a standard battery charging isolators.
Years prior to the sale of the first NC25A, the SES Flexcharge product development team took a hard look at what a new alternative energy charge controller's performance level would need to be to give the user the best possible controller for there needs. From that effort came the following design criteria;
Power Wasted = (Total Charging Current) x (100% - 96%) x (Typical Battery Voltage). P = 25A x 0.04 x 12.6V = 12.6W of wasted energy.
The NC25A operates at 99.5% typical charging efficiency. (99.9% at its best).
P = 25A x 0.005 x 12.6V = 1.57W
In comparing the numbers we see a 11 watt gain in charging energy that is available for your battery bank with the NC25A over the Typical Charge controller.
Question: How much does an 11W solar panel cost? This is precisely why controller efficiency is so critical.
With a peak charging efficiency of 99.9% and an operating current of only 4mA, more of the systems charging energy will get through a NC25A into your batteries than with any other regulator on the market. Models are available for charging 12V, 24V, 36V, and 48V systems. Use with Lead Acid, Gel, or Flooded Nicad battery technologies.
Dependability
There
should never be such thing as a compromise to dependability when it
comes to an alternative energy system charge controller as these systems
are often located in hard to reach locations (mountain tops, ocean
navigation buoys, polar regions, etc...). We took great care to design
the NC25 for long term unattended operation; extensive transient
voltage protection; high steady-state voltage protection (it is not
affected by continuous charging input voltages up to 100V, the point
where the transient voltage protection kicks in); reverse polarity
protection on battery connections; fully sealed electronics for 100%
humidity operation; etc... The NC25A is designed for Install and Forget
operation.
Simple to Operate
The
NC25A includes easy to read Charge and Divert Indicators, an adjustment
for peak charge voltage, and an easy to use terminal strip for the
system wire connections. Because the system charge controller is
usually located near the battery bank in a remote structure we chose not
to incorporate power consuming monitors such as volt meters or current
monitors. If this type monitoring equipment is desired it should be
installed after the system disconnect switch and located where you can
view them.
Easy Upgrades
Upgrading the controller to regulate higher currents can be accomplished easily, and is relatively inexpensive.
