The Johansson 2436 is a 24V stabilised power supply with two RF outputs, designed to inject DC power into coaxial cable runs to supply antenna pre-amplifiers or mast-head units. Its high efficiency level VI rating keeps energy consumption low in always-on antenna installations.

The unit includes short-circuit protection and a power LED indicator on the outputs. It can be mounted on a wall or on a DIN rail using the included mounting clips, making it compatible with standard distribution board enclosures and head-end cabinets.

Key Features

• 24V stabilised DC output
• 2 RF outputs with DC injection
• Output current: 150 mA
• Short-circuit protection
• Power LED indicator on outputs
