Important Installation Notes
Power Conditioning
It is good practice to operate an on-air video server from an Uninterruptible Power Source,
or UPS. All utility power systems experience occasional transient events, including brownouts and
dropouts, which are capable of taking a server off the air. It is the station operator’s job to plan for
and overcome such contingencies.
UPS units suitable for smoothing short-term power line problems come in two varieties:
Change-over UPS Design
This design senses drop-outs and low-line voltage, and switches its output to an internal
inverter operating from a battery. This UPS is low in cost, and is most often used in non-critical
applications such as desk-top computers. A disadvantage is that it may create its own power
transients when switching between utility power and its inverter supply.
Continuous Conversion UPS Design
This improved design continuously converts utility power to DC, stores it in a battery, then
produces isolated AC power from an inverter. It never switches, and is immune to input transients,
brownouts, and blackouts. Models are available with batteries of almost any size, making the
continuous-conversion UPS suitable for transient suppression or long-term operating power in the
absence of utility power.
Recommended UPS Models
The following makes of continuous conversion UPS systems are suitable for use with 360
