Mastervolt Mac 24/12-20
Product code: 81200100
Product Overview
The Mastervolt Mac models are designed to regulate voltage both up and down, ensuring optimal voltage stabilization even when battery voltage fluctuates due to heavy loads. The galvanic isolation between input and output prevents disruptions to communication equipment.
Key Features:
- Professional use
- Converter and 3-step battery charger
- Parallel switchable
- Adjustable and programmable output voltage
- Voltage stabilization for a longer lifespan of halogen lights, etc.
- Dimmer function for Mac & Magic models
- Mac Plus: optimal charging in Euro 5/6 applications
The non-isolated Mac models feature an electrical connection between the input and output. Their benefits include low costs, efficient operation with low heat generation, a compact design, and suitability for applications with negative earthing.
For the Toughest Tasks
Mastervolt Mac DC-DC converters are engineered for demanding conditions in professional, semi-professional, and recreational environments. They operate faultlessly even under extreme conditions, providing reliable, round-the-clock output. With a Mean Time Between Failures (MTBF) of 280,000 hours at full capacity and 24/7 operation, these converters are ideal for challenging situations requiring a dependable power supply.
Parallel Operation
For applications with multiple consumers, the parallel configuration of several Mac units can provide over 100 amperes. Advanced high-frequency technology and modern microprocessors ensure minimal power loss during voltage transitions between 24V and 12V.
Programmable via Laptop or PC
Users can remotely control the Mac or configure personal preferences via a laptop or PC. The device includes a communication port and supports easy installation using a PC-Link and MasterAdjust software.
Energy-Saving Dimmer Function
Unlike standard light dimmers that convert energy into heat and waste power, Mastervolt Mac converters efficiently regulate the power supply. This process minimizes heat build-up, ensuring optimal safety and energy efficiency. Multiple converters can be used for controlling multiple lamps.
