12/24/48V 40A Charge Controller

The Schneider Electric (formerly Xantrex and Trace) C-35, C-40 and C-60 PWM Controllers can be used as a PV charge control, DC load control or DC diversion regulator in 12, 24 and 48 volt systems.   They operate in only one mode at a time, so to provide both PV charge control and low battery load disconnect, two controls must be used.  As a DC load control they disconnect the load at a user settable low voltage and reconnect at the low voltage reconnect point.  As a diversion controller they send excess power to a "dummy load" such as a water or space heater to regulate hydroelectric or wind generators.   All Trace controllers, when used as a charge control, have field-adjustable bulk and float setpoints and perform automatic equalization every 30 days or whenever LVD is reached.  Equalization can be manually initiated.  Order the optional temperature sensor for more accurate battery charge control.  The optional LCD Digital Display shows battery voltage, array amps and watts, cumulative amp-hours and a separately resettable "trip" amp-hour measurement.  The digital display is available for mounting on the front of the charge control, or with a 50 or 100 foot cable for remote mounting in a double-gang electrical box.  Made in China.

NOTE: When used as a diversion controller it must be derated 25%.
