Specification: Origin: Mainland China Type: Module Condition: New Hign-concerned Chemical: None Product details 1. Application voltage 12V 2. Overcurrent (short circuit) protection at the back stage, with lock protection, that is, after the protection is activated, the power switch of the driver needs to be released, and the drive signal will be output only after pressing it again; 3. Frequency 16KHZ to 22KHZ; 4. PCB uses FR4-1.2MM board; 5. Use ST original SG3525A; 6. High-precision chip resistors and capacitors (small error, more stable performance) Pin description 1-pin water protection, 2-pin power supply +12V, 3-pin overcurrent protection sampling, 4-pin power supply negative GND, 5-6-pin drive field effect tube 3-pin and 4-pin are interchangeable according to the actual circuit Product size: 34.00x28.00x13.00mm Product size: 1.34x1.1x0.51inch Note: Due to the different monitor and light effect, the actual color of the item might be slightly different from the color showed on the pictures. Thank you! Please allow 1-2cm measuring deviation due to manual measurement. Included: 1 x SG3525 LM358 Inverter Driver Board 1.
