RO-BEC+ 4A receiver power supply

Robbe RO-BEC+ – Powerful BEC voltage supply for RC models

The Robbe RO-BEC+ voltage regulators are state-of-the-art, separate power supplies for all types of RC models. Whether aircraft, helicopters, RC cars or model ships – the RO-BEC+ provides a safe, efficient and stable power supply for servos and electronics.

Thanks to their compact design, high reliability and flexible settings, the Robbe RO-BEC+ are among the most popular BECs for RC models in the high-end sector.

Flexible output voltage for HV servos

The clocked switching BECs offer a selectable output voltage of 6.0 V, 7.4 V or 8.4 V. This makes them perfect for both standard servos and modern HV servos.

The setting is easily adjusted via a jumper.

Note: When selecting 8.4 V, an input voltage of at least 3S LiPo (11.1 V) is required.

High efficiency & wide input voltage range

With an input voltage range of 7 to 25.5 volts, the Robbe RO-BEC+ can be flexibly operated with 2S to 6S LiPo batteries.

A particularly high efficiency of up to 93% ensures efficient use of the battery capacity and reduces heat generation at the same time.

Compact design & integrated protection functions

The RO-BEC+ impresses with its very small dimensions and minimal weight – ideal for models where space and weight are crucial.

Despite their compact design, all important protective circuits are integrated:

• Protection against overcurrent
• Protection against overtemperature
• Stable output voltage even during load changes

This makes the Robbe BECs ideal even for demanding RC applications.

Variants for every application

The series is available in three power ratings, covering a wide range of model sizes and requirements:

• RO-BEC+ 4 A – ideal for smaller models
• RO-BEC+ 6 A – for medium-sized and versatile applications
• RO-BEC+ 8 A – for large models with high power requirements
