PWM Amplifiers

Started by rguimond, 3 April

1 post in this topic

I'm trying to find a DIN rail-mountable 4-0channel PWM amplifier that is capable of accepting a 5VDC PWM with a maximum frequency of 180Hz and using it to drive 24VDC outputs that energize the coils of proportional solenoid valves at 3A

I purchased one on Amazon, buts it's not readily mountable and one I received always has an output on channel 4 and blows the fuse if I energize output 1, so I have my reservations as to its reliability - https://www.amazon.ca/WALFRONT-4-Channel-Amplifier-Circuit-3-7-27VDC/dp/B07NRPNQXN/ref=sr_1_2?crid=2XK3WMJB6A2MK&dib=eyJ2IjoiMSJ9.FDw_rg5OGgtt425EPx82eKWy1EZ-D7xHfWjbX78mVRPfQrV0tjjaEMgOTCYMpaoGECFOyP9ZtxuMJywY-ih2hSquTEPlveXwpOqxKlr-13_Li7WjFA9b_JjZXOmVZqpXR2EdhkioPBVfrqBTHe999KXKDYD7pamsXMINUzJZQcis3crkLf0-G_iig44VnbsB4D8yAf7NJzfeXFvfjq0np5SMRYat2MqD1O5_07_N00YDmgophypbEckrkxe8F6fnsHYXKYoMiHCLhZqtxe5QxWrOWQuZ6NnIbSk4tA-WBXc.BcNYk9hGzsWq_CNxJDf3TxN2bGuEUwyFe5Y-RUp7Jy8&dib_tag=se&keywords=pwm+amplifier+din&qid=1712149829&sprefix=pwn+amplifier+din%2Caps%2C120&sr=8-2
