1. e you need to cut the red wire in the trio of receiver wires Simply use a pair of wire cutters to remove a short section of the red wire near the Receiver receiver connector and insulate the cut wire with a bit of electrical tape Cut the red wire in the trio of receiver wires Receiver Suggestion You can use a sharp screwdriver to take Take the pin with red the pin with red wire out from the BEC wire out connector of the ESC and then insulate it with a bit of electrical tape for further use so you needn t cut the red wire by this method Wuxi Henge Electronic CO LTD Add No 68 East Zhouxin Road Taihu Town Binhu District Wuxi Jiangsu China Tel 86 510 85069528 http www henge rc com E mail sales henge rc com FAX 86 510 850695282. User Manual of Henge 6A UBEC 1 Specifications 1 1 Output 5V 6A or 6V 6A Changeable with an jumper 1 2 Input e Low Voltage version 7 25 5V 2 to 6 cells Lipo battery pack 6 to 16 cells NIMH battery pack High Voltage version 14 42 5V 4 10 cells Lipo battery pack 1 3 Continuous output current 6A 1 4 Burst output current 8A lt 15 Sec 1 5 Ripple lt 45mVp p 2A 12V 1 6 Size 39mm 21mm 6mm L W H 1 7 Weight 14g Including the cable and the ferrite ring 2 Features 2 1 Designed with an advanced switch mode DC DC regulator IC the max efficiency of the chip is up to 93 2 2 The small size and the light weight make it very convenient to use 2 3 The output current is very large the continuous output current is up to 6A and the burst output current is 8A 2 4 A shield covers almost all the electronic components on PCB and a special made filter ferrite ring is attached with the output wires to significantly reduce the electromagnetic interference 2 5 With ultra wide input voltage from 7V 25 5V Low Voltage Version or 14V 42 5V High Voltage Version 2 6 Shows the working status with an indicator LED lights when the output is in normal range 3 The advantages compared with the linear BEC The comparison of linear BEC and switch mode BEC When using a lithium battery pack more than 3S a switch mode BEC has much higher efficiency than linear BEC For a traditional linear BEC For example a 4S lithium battery pa
3. ck has a typical voltage of 14 8V in order to let BEC output 5V 1A the current flow into the BEC is at least 1A so the power on BEC is 14 8V 1A 14 8W But the useful output power is only 5V 1A 5W so the efficiency of the linear mode BEC is just 5W 14 8W 33 8 the redundant power 14 8W 5W 9 8W changes to heat which makes the BEC very hot and makes it enter protection state thus unable to work For a switch mode BEC in the above case in order to let BEC output 5V 1A the current flow into BEC is only 0 37A actual test data so the power on BEC is 14 8V 0 37A 5 476W and the efficiency of BEC is 5W 5 476W 91 3 4 Special Explanation Although we have tried our best to reduce the electromagnetic interference caused by switch model UBEC it may still cause some interference to the receiver So please install the filter ferrite ring far away from the UBEC s main board and DON T stack the filter on the main board Please put the whole UBEC as far as possible away from the receiver 5 How to use the UBEC 5 1 When ESC HAS NOT built in BEC function No change is needed for the ESC just connect the input cables of UBEC with the battery and plug the output cable connector of the UBEC into one spare channel of the receiver The color of trio wires white red black from top to bottom red Battery Esc ji aiii Cc UBEC 5 2 When ESC HAS built in BEC function You must disable the built in BEC function of the ESC i
