Bosch 8-Dec - Manual (Page 392)

384 | LSN Peripherals | LSN Power Supplies
•
The LSN a/b line current, max. 100 mA, is supplied by
the control panel.
• The NEV 300 LSN can be operated directly next to the
control panel (centralized) or remotely (decentralized).
• Installation cable for LSN technology: J-Y(St)Y
•
Shielding (drain wire) must be routed to the ground
connectors for each LSN line. There must be no
connection between the housing potential and the LSN
cable shielding.
28 V voltage converter (optional)
The basic voltage of the power supply is 12 V. If the voltage
drop is too high due to cable length, a 28 V voltage converter
(optional) can be plugged into the connector board. 28 V
for 2 x +V/0 V and 1 x user output as needed. Power intake
for the three outputs totals 500 mA.
TRN panel relay module (optional)
Panel module with 2 relays for zero potential outputs, one
switching contact per relay. Up to 2 units can be plugged
into the connector board.
