Product Overview

Description

 NC25A/12V   Ultra High Efficiency 25 Amp Solar and Wind System Charging System Controller

For Lead Acid GEL, AGM, and Flooded cell Batteries. Also works with wet cell NiCad batteries.  Do not use on Lithium batteries of any type.

The NC25A/12V 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).  Divert Resistor 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.

Features:

  • 5 YEAR WARRANTY.
  • COMPLETELY SEALED ELECTRONICS FOR MARINE OR OUTDOOR MOUNTING.
  • LOW BATTERY VOLTAGE INDICATOR. (FLASHING RED LIGHT).
  • ARC REDUCTION CIRCUITRY TO ELIMINATE OR REDUCE RELAY CONTACT WEAR.
  • CHARGING EFFICIENCY BETTER THAN 99.50% FROM 0.5A TO 30A OF CHARGING CURRENT.
  • OPERATES EFFICIENTLY (98%) WITH AS LITTLE AS 0.1A OF SOLAR PANEL CHARGING CURRENT.
  • EFFICIENTLY CHARGES BATTERIES FROM 0 VOLTS WITH FULL POWER.
  • 25 AMP CHARGE CAPACITY12V
  • 25 AMP CHARGE DIVERT CIRCUIT. STABLE DIVERT CIRCUITRY PREVENTS ERRATIC RELAY SWITCHING IF CHARGE SOURCE VOLTAGE DROPS.
  • DIVERTS ONLY WHEN VOLTAGE AND CURRENT ARE AT USABLE LEVELS. PERFECT FOR MOTOR TYPE DIVERT LOADS (FANS, PUMPS, etc...)
  • PEAK CHARGE VOLTAGE ADJUSTMENT WITH A RANGE OF 13.8V TO 15.9V (Multiply by 2,3,or 4 to find voltages for 24V, 36V, or 48V versions).
  • CHARGES WITH THE SAME HIGH ACCURACY THROUGH BATTERY ISOLATORS.
  • CONSUMES LESS THAN 5mA (0.005A) WHILE CHARGING AND AT NIGHT, 2mA IF YOU DO NOT USE THE CHARGE INDICATOR.
  • CHARGES BATTERIES AT FULL POWER, BELOW THE PLATE SATURATION POINT, THIS CHARGES BATTERIES FASTER, AND REDUCES ELECTROLYTE DEPLETION BY UP TO 90% OVER CONVENTIONAL CONSTANT VOLTAGE, PWM, & HIGH FREQUENCY CHARGE REGULATORS.
  • BATTERIES START CHARGING AT 0.005A OF CHARGE CURRENT.
  • CONTROLLER CAN WITHSTAND OPEN CIRCUIT INPUT SPIKES OF 1500V/A, & 140V CONTINUOUS WITHOUT DAMAGE.
  • REVERSE POLARITY AND TRANSIENT VOLTAGE PROTECTION ON THE BATTERY SENSE WIRES.
  • NO POWER WASTING SAMPLE PERIODS.
  • REMOTE BATTERY VOLTAGE SENSING SO THE CONTROLLER CAN BE MOUNTED ANYWHERE BETWEEN THE CHARGING SOURCE AND THE BATTERIES.
  • EASY TO INSTALL USING THE LABELED CORROSION RESISTANT NICKEL / BRASS / STAINLESS STEEL CONNECTOR.
  • U/L 94V-O RATED ENCLOSURE AND UL LISTED OR RECOGNIZED COMPONENTS.
