SELECT POWER SUPPLY - STEP 3
Built-In power is often included in the Page Control, so an additional Power Supply may not be needed. The amount of power required for a paging system is based on the quantity and type of Page Control and Speakers/Horns selected.
Easy Selection Considerations:
- Products Provide or Consume Power and are Assigned a Valcom Power Unit (VPU)
- Power Provided is +# or Power Consumed is -#
- Products that neither consume nor provide power are a 0
- Note: One Valcom Power Unit -50mA, -24 Vdc
- VPU listings are on the Product Pages
- Have VPU's left over you can add more speakers
- Need More - Simply Select a Power Supply with enough VPU's to Make Up the difference
Simply Total Example:
a. Page Control VPU's Page Control 1 x +30 = +30 VPU Provided
b. Speaker/Horn VPU's Speakers 15 x -1 = -15 VPU Consumed
c. Subtract b. from a. = +15 VPU's Left
(NO POWER SUPPLY NEEDED)
