Description
Yah microcontroller IC 18018 Ya 23023 Transformer wali kit ka hai
Key Specifications & Features
Model Number: SQEB-SGP-V3R5 (often abbreviated as V3.5 or V3R5).
Package Type: DIP-28 (Dual In-line Package with 28 pins), making it easy to replace on the PCB.
Inverter Type: Specifically programmed for Square Wave “TX” series models (e.g., Microtek EB 700, EB 900).
Voltage System: Standard for 12V DC inverter systems.
Functionality:
Generates the Pulse Width Modulation (PWM) signal for square wave output.
Handles Mains Sensing (detecting when electricity is available from the grid).
Controls the Battery Charging algorithm (Trickle/Boost charging).
Provides protection against Overload, Short Circuit, and Low Battery.
Usage & Troubleshooting
This IC is a direct replacement for damaged controllers on the inverter’s main logic board. Common symptoms of a faulty IC include:
Inverter stuck in “Charging” or “Mains” mode.
Constant “Overload” or “Low Battery” buzzer despite normal conditions.
No output signal to the MOSFETs (inverter does not switch to backup mode).
