BTU rating of IPO modules 1

[Morrack]

Does anyone have any data on how many BTU's of heat each of the various IPOffice modules put out? I would have expected to find that in the technical specifications portion of the installation manual but it's not there, nor anywhere else in the engineering toolkit that I can find.

Any info would be helpfull, thanks all.

Found what I needed.

For those curious:

Unit: 403 406 412 ATM16 DS16 DS30
88.7 54.6 59.73 17.7 81.91 102.4
WAN3 So8 Phone8 Phone16 Phone30
40.95 81.91 40.95 54.6 102.4

Numbers are BTU/hour conversion.

Heat dissipation is measured in British Thermal Units (BTUs). This reflects the maximum (i.e. worse case) amount of heat that can be generated by the equipment and assumes that none of the input power is used to power circuitry and all power is converted to heat, whether from the PSU itself, the system unit, expansion module or cabling.
A heat value expressed in Watts can be converted to BTU/hr by multiplying by 3.41297

Based on the wattages from the product description, you can calculate the notional BTU for IP Office
You use the max power input of 115 VA (rather than the 45W output) of each power supply to calculate this most accurately

Using the conversion factor, BTU/hr = 115W* 3.41297 = 392.5
The metric equivalent to BTU is/are Joules. Convert @ 1,055.

This is number per power supply. So the max BTU per system is calculated by the number of power supplies installed per system

So for a 412, this would be 1 for the base unit; up to 12 for the expansion modules; up to 7 for WAN modules = 20 * 392.5 = 7,850 BTH/hr.
Whereas a Small Office Edition would be rated at 392.5 BTU/hr
The total BTU would also need to consider any outboard equipment (mid-span power for IP Phones; Server PC for apps etc)

Good info, thanks MrIPO - didn't occur to me the data my distributor supplied would only include the actual units, and not the power supplies. Kinda important since they obviously will generate more heat than the actual modules (duh)
