Schneider Electric C35 Charge Controller

The Schneider Electric C-35, C-40, and C-60 PWM (pulse width modulator) controllers can be used as either PV charge controllers, DC load controllers or DC diversion regulators in 12 and 24 VDC systems (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-defined 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 throughput is reduced by 25% when used in diversion mode.

All Schneider Electric C-Series 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 Battery Temperature Sensor can be used to increase accuracy of the control algorithms. The optional LCD Digital Display shows battery voltage, array current and power, cumulative amp-hours, and a separately 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.
