Single Power Supply Module Non Regulated Rectifier Filter Board 8A 3300uF/50V
130.00 EGP
This 8A, 3300μF/50V Rectifier Filter Board is a medium-power, non-regulated DC power supply module that converts AC to DC with reduced ripple. It features an 8A bridge rectifier and a high-voltage (50V) capacitor, making it ideal for higher-voltage applications like audio amplifiers, motor controllers, and industrial circuits where stable but unregulated DC is needed.
Description
🔑 Key Features
✔ 8A Current Rating – Handles moderate power loads reliably
✔ 3300μF / 50V Capacitor – Better ripple filtering for higher voltage inputs
✔ Non-Regulated DC Output – Pure rectified voltage (≈1.4 × AC input)

🔌 Wiring Guide
Input (AC Side):
-
AC ~ → Connect to transformer secondary (~12V-36V AC)
Output (DC Side):
-
+ (Positive) → Smoothed DC output
-
– (Negative/GND) → Common ground
Optional Upgrades:
-
Add a fuse (8A) for overcurrent protection
-
Use a heatsink on the rectifier for prolonged high-current use
-
Combine with a regulator (LM317, Buck Converter) for stable voltage
⚡ Why Choose This Board?
✅ Higher voltage support (50V capacitor) for 24V+ applications
✅ Better ripple filtering than smaller capacitors
✅ Ready-to-use – No soldering required (pre-assembled)
✅ Cost-effective for medium-power projects
📦 Package Includes

⚠️ Safety Notes
-
Do not exceed 50V DC (capacitor limit)
-
Ensure proper cooling for high-current operation
-
Check polarity – Incorrect wiring can damage components
-
For 110V/220V AC input, use an isolation transformer
