Product overview
The RCTimer UBEC 3A UBEC, 5V Switching BEC, identified as 3A-UBEC, is a compact switching battery eliminator circuit. Its electrical role is to provide a 5 V output from a 5–23 V input, with a continuous output current rating of 3 A. Battery input options are specified as 2–5S LiPo or 5–15 NiMH cells, defining the supported battery configurations for integration.
The stated weight is 11.5 g with the ferrite ring, wire and connector included in that measurement. These elements belong in the installation mass allowance alongside the BEC itself. RCTimer positions the unit for use with its ESCs, highlighting models rated 50 A and above because they lack onboard BECs. For those configurations, this unit provides the separate BEC function, subject to its stated input range and 5 V, 3 A continuous output.
