Part 1. Product Introduction
The CX series offers outstanding features in this class. In addition to sophisticated PWM charge regulation with integrated temperature compensation, the CX controllers provide substantial display, programming, and safety functions. The battery state of charge is clearly displayed by means of a bar graph, as well as energy flow from and to the battery and the load status (e.g. overload, load short circuit).
The deep discharge protection function can be set to five different modes: two voltage-controlled, two SOC-controlled,
