Supply Voltage - HBM t40 Montageanleitung

T40

4.4 Supply voltage

The transducer must be operated with a separated extra low voltage
(18 to 30 V nominal (rated) supply voltage), which usually supplies one or
DC
more torque flanges within a test bench.
Should the equipment be operated on a dc voltage network
precautions must be taken to discharge excess voltages.
The notes in this chapter relate to the standalone operation of the T40,
without HBM system solutions.
The supply voltage is electrically isolated from signal outputs and shunt signal
inputs. Connect a separated extra low voltage of 18 V to 30 V to pin 3 (+) and
pin 2 ( ) of plug 1 or 3. We recommend that you use HBM cable
KAB 8/00 2/2/2 and relevant Binder sockets, that at nominal (rated) voltage
(24 V) can be up to 50 m long and in the nominal (rated) voltage range,
20 m long (see Accessories).
If the permissible cable length is exceeded, you can feed the supply voltage in
parallel over two connection cables (plugs 1 and 3). This enables you to
double the permissible length. Alternatively an on site power pack should be
installed.
CAUTION
The instant you switch on, a current of up to 4 A may flow and this may
switch off power packs with electronic current limiters.

Distribution system for electrical energy with greater physical dilatation (over several test benches, for
example) that may possibly also supply consumers with high nominal (rated) currents.
