Intelligent Voltage Regulation and Stabilization

The Magic Series 12/12-20 can regulate voltage both up and down, ensuring a stable output even when input voltage varies due to load changes. This voltage stabilization protects connected equipment and helps extend the lifespan of electrical components such as lighting and sensitive electronics.

By maintaining consistent output voltage, the Magic Series supports reliable system performance under changing conditions.

Galvanic Isolation for System Protection

The isolated Magic models provide galvanic isolation between input and output circuits, preventing electrical disturbances from transferring between systems. This is especially important for protecting communication equipment and sensitive electronics from noise, ground loops, and interference.

Additional protection features include:

• Extra touch-proof construction
• Interference suppression for sensitive equipment
• Availability with negative or positive grounding

DC-DC Converter and 3-Step Battery Charger in One

Beyond voltage conversion, the Magic Series can also function as an advanced 3-step battery charger. When connected to a 12V or 24V service battery, it supports safe and efficient charging for:

• Flooded lead-acid batteries
• GEL batteries
• AGM batteries
• Lithium-Ion batteries

This dual functionality reduces the need for separate devices while maintaining charging precision.

Energy-Saving Dimmer Function

The Magic Series includes an energy-efficient dimmer function, designed to regulate power without converting excess energy into heat. Unlike conventional dimmers, this approach minimizes energy loss and improves overall system efficiency.

Multiple Magic converters can be used together to manage multiple lighting circuits safely and efficiently.

Parallel Operation for Scalable Power

For systems with higher power demands, multiple Magic units can be connected in parallel. Parallel operation allows charging and conversion capacities to exceed 100 amps, while advanced high-frequency technology and modern microprocessors ensure minimal power loss during voltage conversion.

This scalability allows the system to grow without redesigning the entire power architecture.

Configurable and Programmable Control

The Magic Series is designed for flexibility and customization. Output voltage can be adjusted and programmed to meet specific system requirements.

Configuration options include:

• Programming via desktop or laptop PC
• Remote control using MasterAdjust software
• Communication port for system configuration
• PC-Link interface for easy setup

This allows users to fine-tune performance and personalize system behavior with precision.

Designed for Continuous, Heavy-Duty Operation

Built for the toughest tasks, the Magic DC-DC converters are designed to operate reliably even under extreme conditions. With a mean time between failures (MTBF) of 280,000 hours at full capacity and continuous use, the Magic Series is well suited for applications requiring uninterrupted power.

The design philosophy behind the Magic Series reflects Mastervolt’s long-proven approach to durability, sustainability, and performance.

Can Be Used as a Stabilized Power Supply

The Magic Series can operate purely as a stabilized DC power supply, supporting:

• 12V to 12V
• 12V to 24V
• 24V to 12V
• 24V to 24V

In all configurations, inputs and outputs remain galvanically isolated, ensuring system safety and stability.

Solid Connections and Installation-Friendly Design

Reliable electrical connections are supported through:

• Galvanized brass connection blocks with screw terminals
• Chrome-plated fast-on DC input/output connections

Specifications:

• Output: 12V / 12V – 20A
• Weight: 1.8 lbs
• Dimensions: 9.06 × 6.1 × 3.05 in

The compact form factor allows installation in space-constrained environments without sacrificing performance.
