upply voltage
The transducer must be operated with a separated extra low voltage (supply
voltage
9 … 36 VDC). You can supply one or more torque flanges within a test bench
at the same time. Should the device be operated on a DC voltage network
1)
,
additional precautions must be taken to discharge excess voltages.
The information in this Chapter relates to the self-contained operation of the
special torque transducer without HBM system solutions.
The supply voltage is electrically isolated from signal out puts and shunt
signal inputs. Connect a separated extra low voltage of 9 V … 36 V DC to
bracket 7 (+) and bracket 8 (-) of the evaluation unit.
The cable can be up to 50m long for voltages ≥24V, otherwise it can be up to
20m long.
1)
Distribution system for electrical energy with greater physical expansion (over several test benches, for
example) that may possibly also supply consumers with high nominal (rated) currents
At the instant of power-up, a current of up to 4 A may flow, which could switch off power
packs with electronic current limiters.
