The Xantrex C-35, C-40, and C-60 PWM (pulse width modulator) controllers can be used as PV charge controllers, DC load controllers or DC diversion regulators in 12 and 24 VDC systems (only the C-40 can also be used in 48 VDC systems). Two controllers can be used together to provide multiple functions. As DC load controllers they disconnect the load at a user-settable low voltage and reconnect at a higher voltage reconnect point. As diversion controllers they send excess power to a diversion load (See Controls and Relays) to regulate hydroelectric or wind generators. The maximum current throuput is reduced by 25% when used in deversion mode. All Xantrex charge controllers have field-adjustable bulk and float set points and perform automatic equalization every 30 days or whenever low-voltage disconnect (LVD) is reached. Equalization can be manually initiated with automatic shut-off. The optional temperature sensor can be used to increase accuracy of the control algorithms. The optional LCD digital display shows battery voltage, array amps and watts, cumulative amp-hours and a separate resettable "trip" amp-hour measurement. The digital display can be mounted on the front of the charge controller, or with a cable for remote mounting in a double-gang electrical box up to 100 feet away. These controllers are Listed to UL 1741 and CSA 22.2 No 107.1-95 and covered by a 2-year warranty.
