Introduction

Features
The C35/C40/C60 (C-Series) controllers can be used with
12-volt, 24-volt, or 48-volt DC systems (depending upon
model) as Charge Controller or a Load Controller.
Numerous features are provided standard to maximize the
performance of the system:
• Solid-state Pulse Width Modulated (PWM) charging
process with three-stage control, temperature
compensation, and manual or automatic equalization to
maximize system performance and increase battery life.
• Multi color LED with easy to read mode/status label.
• 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.
• Adjustment of charge setpoints is provided by rotary
controls (potentiometers) with removable knobs.
Calibrated scales and test points allow precise
adjustments of settings.
• Over-temperature protection for the electronic circuitry
when used in hot environments (over 113 °F/45 °C).
