NC12L12:

These controllers are in use everywhere between Florida USA, Saudi Arabian Deserts, to Antarctica. With these controllers performing dependably in those locations, you can be assured it will work for you.  

As with all Flexcharge controllers The NCxxLxx Controllers are designed using the latest proven surface mount technology components.  Low standby power consumption is achieved in these controllers with a 6mA typical parasitic current.  Each controller is tested for proper operation prior to being placed into its shipping container. 

Operation
The NCxxLxx use the Flexcharge Charge method described at this link for superior battery operation.

The circuitry is designed to ignore numerous types of false inputs from stray light sources.

Unlike a number of controllers on the market the NCxxLxx controllers switch power to the Positive Side of the Load and the Battery Charging connections.  This allows the user to connect all the system grounds to one location rather than running a separate wire for PV-, Load- and Battery- to the controller, a feature that is required for UL approval.

One small but convenient feature not found on competitors controllers but is included with the NC12L12 is the Manual Low Voltage Disconnect RESET Circuit. This function is also used to test the load circuitry after the installation is completed, and / or when The Low Battery Disconnect circuitry is active. To activate the RESET circuit pass a small magnet over the RED Low Battery Symbol. The load will also illuminate briefly indicating that the Load Circuitry and Low Battery Voltage Disconnect circuit is functioning properly.

Features

NC25A:

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.

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.
