The "LOCK" button locks the machine, preventing misoperation while safeguarding your testing. - Easy to Use: Adjust voltage and current with ease thanks to the sensitive knobs that turn smoothly within 0-30V and 0-5A. The backlit 4-digit large display screen is clear and bright, making it easy to read even in low-light conditions. - Programmable Design: Our power supply unit's programmable operation panel allows users to modify output voltage and current without downloading any software. Change internal parameters such as resistance, capacitance, and inductance to output different voltage stabilization values. - Excellent Heat Dissipation: The build-in cooling fan provides stable and reliable working status, effectively prolonging the service life. The dense heat dissipation holes on both sides dissipate heat in time, keeping the shell cool to the touch. - High Accuracy: Our power supply unit boasts an accuracy of 0.01V (10mV) and 0.001A (1mA) with coarse and fine adjustment, ensuring circuit stability and reducing circuit losses. - C.V. and C.C. Mode: If the load current is less than the preset current limit value, it can be used as a CV source. If the load current is equal to or greater than the preset current limit, the device will automatically switch to DC mode and the voltage will decrease. ## Images ![High Accuracy Lab Bench DC Variable Power Supply - 30V/5A Adjustable Power Supply Variable with 4 LED Digital Display & Programmable Features, Storage Function & Locking Capability - Image 1](https://m.media-amazon.com/images/I/61H0IaZyDBL.jpg) ![High Accuracy Lab Bench DC Variable Power Supply - 30V/5A Adjustable Power Supply Variable with 4 LED Digital Display & Programmable Features, Storage Function & Locking Capability - Image 2](https://m.media-amazon.com/images/I/71JXrgmmKaL.jpg) ![High Accuracy Lab Bench DC Variable Power Supply - 30V/5A Adjustable Power Supply Variable with 4 LED Digital Display & Programmable Features, Storage Function & Locking Capability - Image 3](https://m.media-amazon.com/images/I/61xRVKH2YzL.jpg) ![High Accuracy Lab Bench DC Variable Power Supply - 30V/5A Adjustable Power Supply Variable with 4 LED Digital Display & Programmable Features, Storage Function & Locking Capability - Image 4](https://m.media-amazon.com/images/I/61QAYfFehtL.jpg) ![High Accuracy Lab Bench DC Variable Power Supply - 30V/5A Adjustable Power Supply Variable with 4 LED Digital Display & Programmable Features, Storage Function & Locking Capability - Image 5](https://m.media-amazon.com/images/I/61bdAKpooHL.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.at/products/557789673-high-accuracy-lab-bench-dc-variable-power-supply-30v-5a](https://www.desertcart.at/products/557789673-high-accuracy-lab-bench-dc-variable-power-supply-30v-5a) --- *Product available on Desertcart Austria* *Store origin: AT* *Last updated: 2026-06-04*
