BuschMller USB-WERK AC Dynamo Charging Devices
“Bike mobile“ power supply for mobile devices via hub dynamo.
USB-WERK: Suitable for powering mobile electronic USB devices – e.g. phone,
MP3 player, GPS. Transforms hub dynamo energy.
Scope of delivery
- USB-WERK
- rubber bands
- cable straps
- dynamo connection cable (80 cm)
- cable, circular plug to USB socket
- caps for plug connections
- plug (casing and inner part) for Shimano hub dynamo
- flat connectors with additional branch for SON hub dynamo
- 2 heat shrink tubes for SON flat connectors
Mounting on a bike
The USB-WERK can be fastened to a large variety of frame tubes in any suitable
place by using rubber bands (2) or cable straps
(3). The USB-WERK is splash and rain water proof!
Without mounting: The USB-WERK can
be carried in any bag that allows a cable connected to the hub dynamo to exit.
In this case, the fixing bracket can be removed from the USB-WERK.
Connection to a dynamo/power source
The USB-WERK works with all hub and tire driven dynamos without electronic
voltage limitation. Connect USB-WERK to the dyna-mo with the bared ends of the
connection cable (4) (see the following connection options). Connect the other
end to the input (IN) of USB-WERK (remove cap (6) from plug connection first).
By tightening the screw caps, those connections can be made splash and rain
water proof!
Connection options
Shimano hub dynamo: Twist together one bared cable end each of the connection
cable (4) and the headlight cable. Insert twisted “cable pairs” into each of
the apertures of the the Shimano plug’s (7) inner part (Ill. 1). Please mind
the polarity of the headlight, the USB-WERK has no set polarity. Insert cable
ends as far as possible into the casing, bend them and place them in the
lateral grooves (Ill. 2). Cut overlapping cable strands. Click on the Shimano
plug casing (Ill. 3). Insert the finished plug into the Shimano hub dynamo.
SON hub dynamo: Crimp one connection cable (4) each – shortened if
necessary – together with one headlight cable into a flat connector (8). For
insulation, shrink one of the included tubes (9) around the connec-tors, e.g.
with a lighter flame. Disconnect the headlight flat connector from the dynamo.
Hook the USB-WERK flat connector up to the SON hub dynamo, and connect the
head-light cables once more using the additional branches of the connectors.
Please mind the polarity of the headlight, the USB-WERK has no set polarity.
Other dynamos, also side runners: Connect the cable of the USB-WERK together
with the headlight cable (4) (parallel connection).
Caution:
The USB-WERK can only be used with dynamos (AC power sources). Connection to
DC power sources (batteries) is not possible. If USB-WERK and an IQ-X
headlight are parallel-connected to a hub dynamo, the headlight cannot reach
its maximum possib-le light output.
Connecting/powering/charging electronic devices
Connect the cable (5) (circular plug to USB socket) to the OUT connection of
the USB-WERK. Charging cables of all USB mobile devices can then be connected
to the USB socket.
CAUTION: The USB connection to the devices is neither splash nor rain
waterproof.
The USB-WERK emits up to 500 mA current at a voltage of 5 V.
Most USB devices feature an automatic charging deactivation that prevents
overcharging. If such deactivation is not present and if the device shows the
charge status, the battery must be disconnected from the USB-WERK immediately
as soon as it is fully charged. If such a deactivation is not present and if
the device does not show the charge status, a warming battery is a sign of the
onset of overcharging.
Integrated cache battery
The USB-WERK contains a cache battery that keeps the energy supply constant
during slow cycling or stopping.
If the connected USB device requires more energy than the dynamo is able to
provide, the integrated cache battery contributes the energy difference. (When
cycling slowly, the cache battery discharges, whereas it char-ges when cycling
faster.) When the cache battery is depleted, the energy supply of the USB-WERK
is interrupted so the battery can recharge. As soon as a certain charge has
been reached, energy is once more provided via the USB socket.
Tip:
Cycle for approx. 10 minutes at 15 km/h with the light switched off and with
no USB device connected to ensure a basic charge of the cache battery.
Simultaneous use of dynamo lighting system and USB-WERK
Simultaneous use is possible. Please note that a functioning parallel
operation can only be guaranteed when using a diode rear light and IQ
headlight by Busch & Mueller. The output of the lighting system drops up to
50% depending on the connected device. For other lighting systems, no
statements can be made. Simultaneous operation of ligh-ting system and USB-
WERK diminishes the output accordingly. Please note: Depending on national
law, you may not be permitted to use the USB-WERK and the lighting system at
the same time after dark.
The output voltage of the USB-WERK is insufficient for charging the Busch &
Müller cache battery 461A; it is suitable only for use with the E-WERK (type
361). The USB-WERK already includes a built-in cache battery which keeps the
energy supply constant during slow cycling or stopping.
Technical details
- Ref. no.: 361BW
- In: 0 to 70 V AC voltage, 0 to 10 kHz.
- The limitation is at 100 V peak voltage.
- 0 to 50 V DC voltage. No polarity has to be considered.
- Out: 5 V regulated voltage, short circuit proof
- Output: max. 5 W (fully charged cache battery), 2.5 W permanently
Idle output: 0,05 W at 30 km/h
Charge time of connected USB devices (nonbinding) : approx. 15-20 km/h
comparable to charging with standard mains-connected chargers.
Only if dynamos without integrated electronic overvoltage protection are used
(without the adjacent symbol), the USBWERK can give the highest possible
amount of energy.
CAUTION: If the cache battery was depleted and the USB-WERK not used for
several months afterwards, it is possible that at first no energy can be
supplied. If during the period of non use the USB cable remained connected to
the USB-WERK, discharging can occur more quickly. It takes several minutes of
cycling for the cache battery to possess sufficient energy once more. After
that, normal operation commences.
This can be prevented by charging the cache battery prior to periods of non
use. To do so, it is sufficient to cycle for 10 minutes with the light
switched off and no USB device connected to the USB-WERK.
CAUTION: Busch & Mueller vouches solely for a faultless functioning of the USB-WERK. Exempt from liability is any damage to connected devices of all kinds. It cannot be guaranteed that the USB-WERK is able to power all connectable devices. Please contact the device’s manufacturer. Further information can be found on our website
