Simultaneous use of dynamo lighting
system and USB-WERK
A 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.
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.
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.

Technical details
Ref. no.: 361BW
In:
0 to 70 V AC voltage, 0 to 10 kHz.
Limitation 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 (non
binding): at approx. 15-20 km/h comparable
to charging with standard mains connected
chargers.
Only if dynamos without integrated electro-
nic overvoltage protection are used (without
the adjacent symbol), the USB-
WERK can give of the highest
possible amount of energy.
Technical modifications reserved.
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 de-
vices is neither splash nor rain water proof.
The USB-WERK emits up to 500 mA current
at a voltage of 5 V.
Most USB devices feature an automa-
tic charging deactivation that prevents
overcharging. If such a 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.
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
