This soft start has a simple but very useful design. The circuit will limit the current through the supply wires to 5.5A for about 1.5sec. After that time the relay will close and the current flow won't be restricted anymore. One of the relays has 230Vac coil voltage and you can control the power switch of your amp with a low current stylish switch... The 2 position JST connector is for relay coil switching. Thermal protection is done with KSD-01F D75C. If the thermal sensors reach 75 degrees, your amp will shut down. Dont you want to use thermal protection? You need to short thermal socket pins. 1 and 2 short. 3 and 4 short. Input Voltages: 220-240VAC Output voltages: 220-240VAC Power: till the 1KVA BOM and wiring diagram are going to send buyer email address. Note: We will offer special price for complete finished pcb to you. Please send me message. |
