YaMoRC YD7403 Universeller 3,5-A-Booster Product Details

Description

YaMoRC YD7403 Universal 3.5 amp booster

The YaMoRC YD7403 is a universal booster with an output current of 3.5 amps that has been specially developed to increase the performance of digital track systems. With fully galvanically isolated inputs and various interfaces, it offers versatility and safety - ideal for more complex digital systems with multiple control points, feedback modules or long track sections.

Technical features & equipment

The booster accepts several standard inputs, including LocoNet-B, Roco B-BUS, DCC-CDE or Track Sniffer. It automatically selects the active input and indicates this via an LED. For safety and control, it has a local GO/STOP button that can be used to start the booster or switch it off in the event of a short circuit. It also supports RailCom cut-outs, measures track current and monitors the temperature of the H-Bridge MOSFET output stages.

Electrical data & operating conditions

The YD7403 operates with an input voltage of 15-19 V DC and delivers an output power of up to 3.5 A, realized by modern H-Bridge MOSFET technology. Active short-circuit protection is integrated, as is automatic short-circuit signaling via LocoNet, CDE or B-BUS interfaces. Cooling is passive, as no separate heat sink is required.

Application & compatibility

The device is suitable for model railroaders who need to amplify their track sections or traction currents - for example with long routes or many vehicles at the same time. It can be easily combined with YaMoRC feedback modules, command stations or in environments where several protocols are used in parallel. Configuration is carried out via ES-PGM-LINK.
