They also did not filter any digital noise from one of my digital guitar pedals (draws only 0.5A) to the analog pedal, but that's probably my misunderstanding of how the noise gets to the analog pedal and shows up in the audio signal. i have to use separate power supplies for digital effects units. I wish I could one one and chain the power. That said I would keep these silly things if they would handle the current they said they would. Returning as defective. ## Frequently Bought Together - Rakstore 3pcs 0-50V 4A DC Power Supply Filter Board Class D Power Amplifier Interference Suppression Board Car EMI Industrial Control Panel - 22 AWG Stranded Wire Kit – Silicone Coated Copper Wires 22 Gauge Pre-Tinned 23ft/7m Each Spool, 6 Colors (Black, Red, Yellow, Green, Blue, White), Electrical Jumper Wire Hook Up Wire Kit from Plusivo - Tnisesm/70pcs 2 Pin & 3 Pin 5mm/0.2inch Pitch PCB Mount Screw Terminal Block Connector (Can be spliced) TN-T03B --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.at/products/477286517-3pcs-0-50v-4a-dc-power-supply-filter-board-class](https://www.desertcart.at/products/477286517-3pcs-0-50v-4a-dc-power-supply-filter-board-class) --- *Product available on Desertcart Austria* *Store origin: AT* *Last updated: 2026-09-01*
