I found the label below the connector a little confusing, but after popping the back cover off and looking at the markings on the PWB it became more clear. Also a little puzzled by the 5-30 ma rating. Can it safely source only 3ma at certain settings? If anyone knows, please share. I'm going to drive a 2N3055 with it so I can use some high-current devices. This might be used in many projects - strobe light, spark generator (with auto ignition coil, crude (square wave) audio generator, incandescent light flasher, motor speed controller, etc. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vu/products/97406094-yeeco-signal-generator-adjustable-3-3-30v-12v-24v-1hz](https://www.desertcart.vu/products/97406094-yeeco-signal-generator-adjustable-3-3-30v-12v-24v-1hz) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-12*
