Schneider Electric XW+ CONFIGURATION TOOL
The Schneider Electric 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.
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.
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
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.
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.
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.
A simple to read, multi-color LED
indicates operating status and is standard on all C Series controllers.
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.
