Using potentiometer adjustment method, simple to use, easy to adjust. With constant current, constant voltage (CC, CV) mode, the current mode can be used to simulate a resistive load to discharge the battery pack to power load; their voltage mode can be used to simulate the capacitive load to charge the load, and simulate the LED to the LED drive power constant voltage characteristic load. With perfect protection function, and its performance and functionality is the traditional slide wire resistor can not be compared for the related industries can greatly improve production efficiency and reduce costs. ## Features - Model:KL283 Electric current：30A：15A X 2 Voltage：300W：150 X 2 Voltage and current are five LED high precision digital display , overvoltage/over current/power/hot/reverse polarity protection , operating mode with constant voltage and constant current. Have separate two independent input channel, constant current mode can be parallel, constant voltage mode to series; Optimization of the cooling structure for high power density far look the function of the test part (models) have external analog quantity control and the remote ON/OFF, the CC/CV switch operation (models); equipped with non-slip feet portable strong case smart fan control ›See more product details ## Images ![300W 80V 30A Dual Channel Adjustable LCD DC Electronic Load Instrument 220V - Image 1](https://m.media-amazon.com/images/I/412tvK0oM3L.jpg) ![300W 80V 30A Dual Channel Adjustable LCD DC Electronic Load Instrument 220V - Image 2](https://m.media-amazon.com/images/I/41UnPgEHZRL.jpg) ![300W 80V 30A Dual Channel Adjustable LCD DC Electronic Load Instrument 220V - Image 3](https://m.media-amazon.com/images/I/41XLsjDC++L.jpg) ![300W 80V 30A Dual Channel Adjustable LCD DC Electronic Load Instrument 220V - Image 4](https://m.media-amazon.com/images/I/41JYAsQuKQL.jpg) ![300W 80V 30A Dual Channel Adjustable LCD DC Electronic Load Instrument 220V - Image 5](https://m.media-amazon.com/images/I/51C7xEsz2lL.jpg) --- ## 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.kr/products/179816788-300w-80v-30a-dual-channel-adjustable-lcd-dc-electronic-load](https://www.desertcart.kr/products/179816788-300w-80v-30a-dual-channel-adjustable-lcd-dc-electronic-load) --- *Product available on Desertcart South Korea* *Store origin: KR* *Last updated: 2026-05-12*
