XANTREX C12 Controller

The Xantrex/Trace C12 charge, lighting, or load controller is uniquely sophisticated. As a charge controller, it features three-stage charging, user definable voltage parameters, and automatic equalization. Standard in the C12’s load control circuitry are field adjustable low voltage disconnect and reconnect points, along with a five minute low battery disconnect warning. The C12 also functions as a lighting controller. Lighting run time is adjustable from 2 to 8 hours or can be set from dusk to dawn operation. It is used worldwide in a variety of applications, including remote village lighting systems and automatic outdoor lighting in Africa, Latin America, and Asia. An optional battery temperature sensor ensures precise battery charging regardless of battery temperature fluctuations.

Photovoltaic Charge Controller
Silent, solid state, series pulse width modulated (PWM) charge control with 3-stage (bulk, absorb, & float).
Field adjustable setpoints with removable knobs to reduce tampering (bulk range: 13.0 to 17.0 VDC).
Electronic short circuit, overload, overtemperature and reverse polarity protection improves reliability.
Automatic reset of overload protection system–eliminates problems of tripped breakers and blown fuses.

High efficiency, "No diode" design without electronics in the negative conductors (as per NEC code).
Optional plug-in/replaceable temperature compensation sensor –ideal for sealed batteries.
Continous rating of 12 amps @ 113F /45C and 8 amps @ 150F/65C for severe environments.
Designed for 15 amps of short-circuit PV array current (typically about four 50 watt modules).
Two stage lightning and surge suppression through both active and passive protection components.
Equalize mode (@ bulk+1DC for 2 hours) with automatic activation every 30 days or if LVD is reached (defeatable).

DC Load Controller
Automatic low voltage disconnect (LVD) with adjustable setpoint (LVD range 10.5 to 12.5 VDC).
Automatic low voltage reconnect (LVR) with adjustable setpoint (LVR range 12.0 to 14.0 VDC)
Selectable automatic or manuals reconnection of loads after low voltage disconnect occurs.
Electronic short-circuit, overload, overtemperature and reverse polarity protection improves reliability.
Continous rating of 12 amps @ 113F /45C and 8 amps @ 150F/65C for severe environments.

Low voltage disconnect warning system–blinks loads on-off-on when the battery voltage is below the low voltage disconnect setting after a two minute delay. Loads are then disconnected after a 5 minute additional time delay unless loads have been reduced and voltage has risen above the low voltage disconnect setpoint.
Manual reset switch on bottom of enclosure allows one-time 10 minute grace period for operation of DC loads after reset has accurred. Additional pushes have no effect until voltage reaches the low voltage reconnect setting.

Automatic Lighting Controller
Automatic control of lighting systems with nighttime detection by using the PV array as a photocell.
Adjustable run duration from 2 to 8 hours or "dusk to dawn" all night operation of lights, unless LVD is reached.
Electronic short-circuit, overload, overtemperature and reverse polarity protection improves reliability.
Continous rating of 12 amps @ 113F /45C and 8 amps @ 150F/65C for severe environments.
Manual reset switch on bottom of enclosure allows testing of lights during daytime or after LVD has accured.
