FEATURES
1. PWM Charge control - Depending on the actual battery level, various charging procedures, float charging
and boost charging are automatically performed.
2. Deep discharging protection - If the battery falls below a specified voltage (11.0V/22V), the load output is
disconnected preventing excessive discharge of the battery. Once the voltage increases to 12.0V/24V the
load will be automatically re-connected. The set points of the deep discharging protection are predefined
and cannot be reset.
3. Two timers can be set to turn the loads on and off automatically.
4. Temperature Compensation
ISC3042 has an internal ambient temperature sensor that compensates during the float mode. This functions
only when float voltage setup is set to “OFF” (See item no. 4 page 5)
5. MPPT function - Implementing the latest MPPT technology the controller is able to harness the panels
maximum available output at all times.
6. 5V USB output provides 5Vdc/ 500mA power supplier
