Description
- Microtek OLD Refurbished PCB
- 12v INVERTER PCB
- 100% Tested
- Non TX PCB
- Inverter Manages the primary function of converting DC battery power to AC power (the power supplied to your home appliances) when the mains supply fails. Some models use Quasi Sine Wave or Pure Sine Wave output, which is controlled by the circuitry on the PCB.
- Battery Charging Management: Employs a Multi-stage Charging system, often PWM Controlled (Pulse Width Modulation), to ensure the battery is charged safely and efficiently, maximizing its life.
- Protection Circuitry: Integrates essential safety features to protect both the battery and the connected load:
- Overload/Short Circuit Protection: Automatically shuts down the output if the load is too high or a short circuit occurs.
- Deep Discharge Protection: Prevents the battery from being over-discharged.
- Temperature Shield: Monitors internal temperature and shuts down if overheating is detected.
- 🧩 Main Components on the PCB
- While the exact layout varies, the board generally contains:
- Microcontroller IC: The central processing unit (e.g., a variant of the SQEB SGP V3 R5 or EBHB-SGP-V3R3 series) that executes the control logic for charging, inversion, and fault detection.
- Power Circuitry: Includes MOSFETs (Metal-Oxide-Semiconductor Field-Effect Transistors) and a Driver
