PowerLoop Calculator Tool
The Power In, Power Out and Cable Loss are calculated.
Power In: Power supplied to the BSD-340, i. e. the total power
consumption.
Power Dissipation: To find out the total power/heat budget, the
dissipated power from the BSD-340 inside the rack can be calculated.
Simply calculate the power dissipation by Power In minus Power Out.
Then add a comment in the Help about this field, to inform of the
intention.
Power Out: Power delivered to the loop from the BSD-340.
Cable Loss: Power lost in the cable. It should be observed in order to
ensure efficiency in the system, this is wasted power.
6.2.3 Insert Row Button
• Select a row in the list box above to insert the new row by clicking
the leftmost field.
• Enter the cable length, cable resistance (in Ohm per km), plus
external power for BN-342/EX unit if necessary.
• Enter a textual description of the cable type and square area (or
diameter) for information in the “cable dim/type” box.
• Select the detector type, then press the Insert Row Button.
When pressing the Insert Row Button, the tool automatically
performs a new calculation and verification.
6.2.4 Update Row Button
• Select a row in the list box above to update a row.
• Change the cable length, cable resistance (in Ohm per km), plus
external power if necessary and/or detector type.
• Press the Update Row Button.
When pressing the Update Row Button, the tool automatically
performs a new calculation and verification.
