Schneider Electric RNWC35 > 35 Amp 12/24 Volt PWM Charge Controller
Manufacturer Part Number: RNWC35
The Xantrex C35 is a controller for virtually any DC charging source. The C35 is field configurable for 12 and 24 VDC operation. It can be used as a charge, diversion, or load controller and comes with a standard multi-color charge status LED. It is a fully solid state, microprocessor-driven controller that is UL and cUL listed.

Display Panel: CM, CMR/50 or CMR/100-A back-lit meter which continuously displays: battery voltage, DC amperage, cumulative amp hours and amp hours since last reset. CM mounts on front of C Series, C35, C40 and C60, charge controllers. The remote meters CMR/50 and CMR/100 use simple telephone type plug-in connectors. 50 ft. (15 m) or 100 ft. (30 m) cable included.
Battery Temperature Sensor: BTS/15 or BTS/35 Monitors battery temperature and adjusts charging voltage for maximum performance. A 15 ft. (4.5 m) or 35 ft. (11 m) cable with standard telephone type connectors is included.
Silent Microprocessor Control
All C Series controllers have a powerful microprocessor at their core which increases system performance and maximizes battery life. They are fully solid state and operate silently.
PWM Charge Performance
C Series controllers all use Pulse Width Modulation (PWM) charging profiles which are designed to provide a full charge to your battery while, at the same time, minimize gassing which can shorten battery life.
3-Stage Battery Charging
All C Series controllers automatically initiate a 3-stage battery charging cycle. Bulk, Absorption, and Float modes are used to ensure that voltage and current settings accurately match the batteries' actual state of charge. This means fast-as-possible charging and extended battery life. An auto equalize mode can be easily switched off when the controller is used with sealed batteries. C Series controllers are factory set for solar PV battery charging operation.
There are a number of field configurable, user adjustments for C Series controllers. C35 and C60's can only be set for 12 or 24 VDC operation. The C40 may be configured for 12, 24 or 48 volt systems. Bulk and Float voltage set points are user adjustable which allows use with a wide variety of battery technologies including; flooded lead acid, gel, and absorbed glass mat. In addition, there are manually selectable settings for Nicad batteries.
DC Load Controller Mode
When used as a load controller, the C Series will automatically turn a DC load on or off at predetermined battery voltage settings. Both LVD (low voltage disconnect) and LVR (low voltage reconnect) set points are user adjustable.
DC Diversion Mode
In this mode, all power, which is not used to maintain a full charge on the batteries, is diverted to a load dump such as water or space heaters. Diversion mode is used to regulate microhydro and wind turbine systems which need a constant load.
LED Status Indicator
A simple to read, multi-color LED indicates operating status and is standard on all C Series controllers.
UL and cUL Listed
C Series controllers are listed by UL to exacting UL 1741 and cUL CSA 22.2 107.1-95 standards. C Series controllers are also CE compliant (European countries) and are designed to CTIK standards (Australia). Their current ratings are "real world" and do not have to be derated to comply with USA NEC 125% over-current requirements.
