Product Overview

The Cotek SC1200-112 is a bi-directional power solution, meaning it can convert DC power from batteries into AC power while also charging batteries from an AC power source when available. This ensures a continuous power supply while protecting batteries from deep discharge and extending their lifespan.

This unit is engineered with 5 intelligent operating modes to optimize power usage:

1. Inverter Mode: Supplies AC power from the battery when no external AC source is available.
2. Charger Mode: Charges the battery using AC input when an external source is connected.
3. Power Sharing Mode: Balances power between the AC source and battery to prevent overload.
4. Power Generation Mode: Utilizes both AC input and battery power to support higher loads.
5. Power Support Mode: Adjusts AC input current to prevent overloading external power sources like generators.

The automatic AC transfer switch ensures a seamless transition between power sources, minimizing downtime and ensuring continuous operation. The built-in power-sharing feature prevents overloading the AC input source by adjusting the charging current when other appliances are drawing power.

The SC1200-112 features a highly efficient 3-stage battery charging system, ensuring optimal battery health for lead-acid (AGM, Gel, Flooded) and lithium-ion batteries. An optional battery temperature sensor adjusts the charging parameters based on temperature fluctuations, improving performance and extending battery life.
