BUG 3/2/20 Basic Feed Unit

5.96064.02
Remarks on the Technical Data
1)
Connection voltage of the basic unit = secondary voltage U
2
of transformer T
1
.
Rated value: 230 V; never directly connect devices to the mains.
2) Max. permissible non-repetitive peak current (t < 10 ms) at switch-on; this is limited by the induc-
tivity of transformer T
1
on the input side and possible additional current limiting resistors, R
2
(refer
to the transformer layout); switch-on frequency: once per half hour.
3)
Controller supply (switching power supply); the total of all the triggering power of all the BUS de-
vices may not exceed the power of the selected BUG unit's switching power supply!
4)
Additional feed for the mains unit; useful when carrying out trouble-shooting with a test adapter
BU; the isolating transformer (T
2
) is specially matched to the mains unit; transformer T
2
is not
needed for operating the basic units.
5)
Power losses of the devices; on one hand, this is important for rating the switching cabinet, and
on the other for rating the BUG basic unit:

(BUG) (see also Transformer Rating)
6)
Coolant temperature measured 50 mm below the device according to DIN VDE 0160/DIN VDE
0558 Part 1; in rated operation, T
K
as well as T
B
must be below the specified limit temperatures.
Otherwise, you must reduce the device's rated current.
7)
Operating environment temperatures measured 300 mm away from the unit at the most, halfway
up the device according to DIN VDE 0160/DIN VDE 0558 Part 1; T
B
and T
K
must not exceed the
specified limit temperature. The same conditions apply as before.
