Buy SG3525 Inverter Driver Board at store.tajr.pk. Adjustable 13-40KHz PWM module for 12V-24V DC to AC converters. Reliable power for DIY inverters.
Description
The SG3525 Inverter Driver Board is a high-performance PWM (Pulse Width Modulation) control module designed for building powerful DC-to-AC inverters and switching power supplies. Built around the industry-standard SG3525 IC and LM358 operational amplifier, this board provides a stable, adjustable frequency range of 13KHz to 40KHz. It is specifically engineered to drive high-power MOSFETs, making it capable of handling large-scale projects like 5000W motor drivers or home inverters. With built-in protection features like overcurrent (short circuit) locking and power transposition protection, it ensures both the safety of your components and the user.
Features
Dual-Chip Design: Utilizes the SG3525 PWM controller for stable signal generation and the LM358 for precise protection logic.
Adjustable Frequency: Easily tune the output from 13KHz to 40KHz to match your specific transformer or motor requirements.
High Driving Power: Equipped with high-current TO-220 output stages, capable of driving massive loads.
Safety First: Includes "locking" overcurrent protection; if a short circuit occurs, the board shuts down and requires a manual reset (power switch toggle) to resume.
Safety Function: Features an adjustable 7.6s automatic power-off function to protect users from accidental contact (can be disabled by removing resistor R7).
Reverse Polarity Protection: Protects the board from damage if the input power wires are connected backward.
Applications
DC to AC Inverters: The core component for converting 12V/24V battery power to AC for household appliances.
High-Power Motor Control: Ideal for driving large DC motors and industrial actuators.
Ultrasonic Cleaners: Can be used as a driver for high-frequency ultrasonic transducers.
Switch Mode Power Supplies (SMPS): Great for DIY lab power supplies and battery chargers.
Educational Projects: A perfect tool for students learning about PWM, frequency adjustment, and power electronics.
Parameters
Input Voltage: DC 12V to 24V.
Frequency Range: 13KHz – 40KHz (Adjustable via onboard potentiometer).
Output Drive: Dual totem-pole outputs (can source/sink up to 200mA-500mA peak).
Max Load Capacity: Can drive power stages up to 5000W (with appropriate MOSFETs).
Automatic Shut-off Time: 7.6 seconds (adjustable via R7).
Protection Type: Locking overcurrent protection and power transposition protection.
Board Material: High-quality metal film resistors and industrial-grade PCB.
