C40
Charge-Diversion
& Load Controller
Introducing the C40
The C40 controller is the finest large-system
controller available. The C40 can be used with
12, 24, or 48-volt DC systems as a PV charge
controller, a DC diversion controller, or a DC
load controller (low voltage disconnect). These
capabilities make the C40 the only DC controller
you’ll need! Numerous standard features are
provided to maximize the performance of the
system:
Silent, solid-state Pulse Width Modulated
(PWM) charging process with three-stage
control, temperature compensation, and
manual or automatic equalization.
Maximizes system performance and
increases battery life.
Meets National Electrical Code (NEC) and
other international controller specifications.
Certified by ETL for the U.S. (UL Standard
1741 (draft), and Canada (CSA-C22.2 No.
14-M91 SEP 91)
Electronic overload and short circuit
protection with automatic and manual reset
capability increases the reliability of
unattended systems by eliminating blown
fuses and tripped circuit breakers
Field adjustment of charge setpoints is
provided by rotary controls with removable
knobs, reducing the potential for setpoint
tampering. Calibrated scales and test points
allow precise adjustments of settings
Optional external battery temperature compensation sensor (BTS) for automatic
adjustment of charge setpoints (required by UL draft standard 1741 and strongly
recommended for sealed batteries)
Over-temperature protection of the electronic circuitry (by reducing the charge rate)
improves the reliability of the C40 when used in environments over 113 F / 45 C.
Indoor-type, powder-coated enclosure for wall mounting
Multi-color status LED with matching color label for mode/status indication
Optional LCD meter for remote or direct mounting on the C40. May be mounted up to
1000 feet away
2 year limited warranty
