The input voltage range of the indicator box is 6 - 55 volts DC, so it is not suitable for connection to the hub dynamo.
The output is 12 volts for the turn signals.
The electronics of the velorian e-bike indicator set are protected against reverse polarity, so nothing will break if the plus and minus connections are reversed. It simply does not work.
Cable 1 is 2-core for the power supply is connected to the power source on the e-bike. This can be the connection cable of the headlight, or a separate connection cable for additional consumers, as many e-bikes have, or the battery itself.
Cable 2 is 4-core and contains the connections for the rear turn signals.
Cable 3 has 10 wires and contains the connections for the front turn signals and the indicator switch. The cables on the blinkerbox are replaceable. If you cut too short during assembly, this is annoying, but can be remedied by unscrewing the housing and reinserting a new longer cable.
The blinkerbox has a sound generator that makes the flashing audible. The sound is almost like the ticking of the indicator in a car and is just loud enough to be heard while driving. If you find the ticking annoying, you can switch it off via the indicator box configuration.
The e-line alpha22 blinkerbox is pin-compatible with the previous version, the e-line alpha21 blinkerbox.
- improved noise immunity
- reduced power consumption via standby function for all those who operate the e-line with a separate battery up to 12 volts.
- Modification of the circuit in that the earth cables can now be laid together.
- Reduced standby current of only 0.8 mA
