Ensure optimal voltage stabilization even amidst heavy loads with the Magic Series DC-DC Converter. Designed for professional use, this converter doubles up as a reliable 3-step battery charger, ensuring your equipment runs smoothly without disruptions. Its unique capability to regulate voltage both up and down guarantees stable performance, even when battery voltage fluctuates. With galvanic isolation between input and output circuits, it safeguards sensitive equipment from disruptions, making it ideal for communication setups.

Crafted for versatility, this converter boasts adjustable and programmable output voltage, allowing you to customize settings based on your specific requirements. Whether it's ensuring a longer lifespan for halogen lights or enabling dimmer function for Mac & Magic models, this converter delivers exceptional performance. With interference suppression features and the option for negative or positive grounding, it's a must-have for any professional setup.

Programmable Control

Easily program and control the Magic converters using a desktop, laptop, or PC. Utilize the communication port and MasterAdjust software for seamless configuration.

Energy-Efficient Dimmer Function

Unlike standard light dimmers that waste energy as heat, Magic converters efficiently regulate power without excessive heat buildup, ensuring safety and energy savings.

Parallel Operation

Need more power? Configure multiple units in parallel to achieve over 100 amperes. Advanced technology minimizes power loss during voltage switching, maintaining efficiency.

Built for Tough Conditions

Designed for professional, semi-professional, and recreational use, Magic converters excel even under extreme conditions, offering reliable round-the-clock performance. With a proven track record of sustainability and technology, they provide uninterrupted power supply when needed most.

Versatile Power Supply
