Solar PWM Battery Charging Controller , Auto Voltage, 12/24V In 12/24V out, 8A Features 3 stage PWM with automatic overdischarge protection for extended battery life Very low self consumption Applications Remote Power Systems UPS Systems Description Tycon Power Systems solar controllers are 3 stage PWM type battery charging controllers controlled by an industrial CPU. The controllers are available in 12V and 24V to accommodate different battery voltage systems. They have full electronic protections for short circuit, reverse current, overvoltage, overcharge and over discharge. The built-in overdischarge protection and low self consumption ensures the battery is not overdischarged, which greatly increases the life of the batteries. They have three multifunction LED indicators to give a quick visual status of the load status, if battery is charging or fully charged, as well as any fault condition. Connections are via 6 screw terminals for wire size up to 10AWG. The controllers are externally fused with a standard replaceable fuse. There are four screw holes(4mm) for mounting.
