  • 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.

Detailed Description

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.

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.

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.

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.

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.

Status Indicator

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.
