C-Series Charge Controller
C Series

The C40 has long been the mainstay of our charge controller line-up, its versatility and reliability have made it an industry standard. Now the C40 is joined by two companion controllers, the C35 and C60.

Product Info | Specifications | Datasheet

Description
A Controller for Virtually Any DC Charging Source

The C Series, including the C35, C40 and C60, is the benchmark of our charge controller lineup. The C35 and C60 are field configurable for 12 and 24 VDC operation. The C40 may be configured for 12, 24, or 48 VDC operation. All can be used as a charge, diversion, or load controller and come with a standard multi-color charge status LED.

All three of these fully solid state, microprocessor-driven controllers are UL and cUL listed. Whatever the charging source, a C Series controller is sure to meet your DC controller needs.

Product Features

  • Ensures your batteries are always charged
  • Silent, pulse width modulated microprocessor control (maximizing battery life)
  • Field adjustable voltage and battery set points
  • Electronic protection against short-circuit, overload, over temperature and reverse polarity conditions.

Optional Accessories:

  • CM: Cumulative amp hour meter
  • CM/R: Remote cumulative amp hour meter (available in 50 or 100 foot lengths)
  • BTS: Battery Temperature Sensor
