Power Supply Requirement Worksheet; Figure 71 - Amperes Drawn Per Total System Wattage - MTI Matrix System Series Manual

Step 2
Take the figure derived in step 1 and match it to the closest "Total Watts" amount in
the table below. If yours is between two amounts, round up to the next highest in the Table.
Figure 71 – Amperes Drawn per Total System Wattage
Step 3
Find the corresponding "Amperes Drawn" amount from the table. This is your power
requirement. If necessary, multiple power supplies can be used to provide the current as
required by the Amplifiers in your Switching System. See page 77-78 for instructions for
connecting two 50-amp Astron Power Supplies in parallel.
Example 1:
1200 watts = 86.96 Amperes drawn. Requires two 50 ampere power supplies.
Example 2:
1400 watts = 101.45 Amperes drawn. Requires two 50 ampere power supplies.
