We supply a variable speed drive designed specifically for heating, ventilation and air conditioning (HVAC) applications: the SED2. This drive offers all the standard features that
could be expected from a variable speed drive designed for HVAC applications. What’s more, the SED2 incorporates a host of unique features and functions that make this drive a state-of-the-art product.
Details
Typical applications for the SED2 drive are variable torque fans and pumps. To reduce harmonic currents on the AC line, we have developed a technology for use with the SED2 that does away with extra components such as AC line reactors. The technology is called low harmonic technology (LHT). Tests reveal that LHT clearly leads to a reduction of low order harmonic currents on the AC line. In contrast to standard variable speed drives, the SED2 delivers good test results without using AC line reactors.
Harmonics characteristics of the SED2 are comparable to or even better than those of variable speed drives equipped with extra AC line reactors or DC link chokes.
Another benefit offered by the SED in connection with fans and pumps is its considerable energy saving potential, which also brings cost savings.
Features
We offer:
- Low harmonic technology (LHT)
- Energy saving variable speed technology
Benefits
The new technology brings the following benefits:
- Direct cost savings, since AC line reactors are not needed
- Lower maintenance costs, since the motors produce less heat, leading to longer motor lifecycles
- Added protection for sensitive equipment such as computers and communication modules, etc.
