Low voltage power supply (12V/24V) for DC motors
Regulated with built in current sensor.
The LCN-NH12/-NH24 module converts 230V outputs for shutter and blind motors into low
voltage. (12V DC or 24V DC, module description: LCN-NH12 or LCN-NH24, (please be
aware when ordering.) The LCN-NH12/-NH24 module has an intregated direction toggler
(+/-) with locking: controlling both direction inputs at the same time, is no problem. Apart
from that, the power supply has an internal current sensor, that can be evaluated over an
external binary sensor (LCN-B3I/ -BU4L).
How it works with DC motors:
The LCN-NH12/-NH24 is connected to the outputs of an
LCN-SH, -SHS or -HU module (see illustr.) The outputs
of the module must be set to motor switch and filters
deactivated (see data sheet LCN-SH / -HU). The motor
is to be connected to terminals as described in the
illustration. The controlling of the electrical motors is
carried out over the commands motor / shutter (move
UP, move DOWN or single control mode). Alternatively
the power supply input feeds can be carried out through
any other contacts, e.g. LCN-R8H.

A special feature is the intregated current sensor, that can be evaluated over an external
binary sensor (LCN-B3I/LCN-BU4L). This type of monitoring can be used for example for
error messages like (motor is running / is not running!). For this, the binary sensor is
connected to the terminals as shown on page 1.
the white terminal on the common (N/M) connection from the LCN-B3I/-BU4L, the black
terminal on the desired input (motor is running = input is activated).
Note:
A parallel connection from LCN-NH12/-NH24 modules, is only possible over an
interposing relay. (e.g. LCN-R4M2H)
Polarity:
when phase (L) on terminal R1 then orange = minus (-), blue = plus (+)
when phase (L) on terminal R2 then orange = plus (+), blue = minus (-)

Connecting as power supply:
The LCN-NH24 can also be used as a simple power supply,
as query voltage for a sensor module (LCN-BU4L) .
The power supply offers an electrical isolation from the
query voltage to the mains power.
The power supply is connected primary side on the R2
(phase) and to the N terminal. On the secondary side, the
blue terminal (see illustr. on the right) is connected to the
M terminal of the LCN-BU4L. The orange terminal then
branches off to the single push-buttons/switches.
