Introducing the SED2
Variable Speed Drives
Designed specifically for HVAC applications
From a global leader in drives technology
and HVAC now comes a drive specifically
configured for HVAC applications. Introducing
the SED2 variable speed drive from Siemens
HVAC Products division.
Incorporating the latest advancements in IGBT
technology, the SED2 is a PWM drive packed
with all the standard features you would expect from a drive designed for HVAC applications, plus many more additional unique design features and capabilities that makes this
drive truly advanced.
All the features you would want from an
advanced HVAC variable speed drive
• Integrated communication for fast and
easy network integration
• Ni 1000 input (RTD) for autoconfiguring
of field devices
• Built-in PID for fast and accurate pressure
control using pumps and fans
• Low harmonics design reduces noises and
interference
• Pump cascading with 3 pumps
• Parameter assignment matched to
user needs
• Belt failure detection without an external
sensor
• Essential service mode for applications
requiring continuous, uninterruptible
operation
2
• One common interface throughout all
power ranges
• Optional plain text operator panel with copy
and time scheduler function
