The Central Box 400 is a switchboard designed for the complete management of servos in large to giant models with an emphasis on safety. The Central Box 400 has a unique design that provides overload protection at each servo output. An independent, very powerful BEC (battery eliminator circuit) for each battery input makes the Central Box an optimal solution to connect up to 24 servos. The Central Box 400 can manage the batteries and fully supports the JETI EX telemetry system. Up to two receivers with serial (PPM, EX Bus, UDI) output can be connected to the Central Box 400. With a JETI DC/DS transmitter, the full potential of the Central Box can be used, such as easy configuration of the Central Box, EX telemetry, and very fast servo response.

Central Box 400 supports up to 24 protected servo outputs, two battery inputs with voltage regulators and incorporates  possibility to connect an RC or magnetic switch.
