Know before you buy
Yes, the unit features a 3-step charge mode that can be activated via DIP switch settings, allowing it to function as an effective battery charger.
Yes, you can adjust the output voltage between 20V and 28.5V using the MasterAdjust software, providing flexibility for specific equipment requirements.
The unit includes maintenance-free vario fans for cooling. While it is designed for demanding conditions, ensure there is adequate airflow around the unit to prevent derating, which occurs if the ambient temperature exceeds 40°C.
Yes, the converter is MasterBus compatible when used with a MasterBus Serial Interface, allowing for centralized monitoring and control within your existing system.
The converter includes built-in protections against overloads and over-temperature. It also provides galvanic isolation to ensure safe operation and prevent electrical interference between your input and output circuits.
The dimmer function can be activated via a DIP switch setting and controlled using an external momentary switch connected to the fast-on terminal. This allows you to adjust the output voltage between 8V and 26V.
