Building Technologies SED2 Variable Frequency Drives
More standard features Means better control of HVAC applications The global leader in Heating, Ventilation and Air Conditioning (HVAC) products and systems, Siemens delivers the SED2 family of Variable Frequency Drives, designed specifically for HVAC systems and applications. Using the latest IGBT technology, the SED2 Variable Frequency Drives are PWM drives loaded with features for HVAC variable torque applications such as speed control on fans and pumps.
The Siemens SED2 VFDs use a unique low harmonic design that eliminates the need for DC link chokes and line reactors. In addition, Siemens Harmonnee® software calculates the harmonic distortions produced by the drive on your electrical system and compares them to IEEE standards to ensure compliance. The result is reduced expenses and the ability to use a smaller drive. That adds up to dollars and sense.

Variable Frequency Drives Designed specifically for HVAC applications, the SED2 family of VFDs supports a wide variety of digital and analog inputs and outputs for maximum control flexibility. Built-in PID features control pumps and fans, and an integral system protocol can interface P1/N2 networks. Using the SED2 multi-level parameter access, operators can quickly pinpoint relevant data.
VFD with Electronic (E) Bypass Option Electronic (E) Bypass Options are companion packages for SED2 Variable Frequency Drives that provides electronic control and simple keypad operation to streamline installation, simplify control wiring, and improve system reliability.
VFD with Conventional (A) Bypass Option Conventional Bypass Options are companion packages for SED2 Variable Frequency Drives that streamlines installation and simplifies control wiring. Bypass Power Features 2-Contactor: Output and Bypass provides overload protection in bypass mode with a step-down transformer with fused primary and secondary. Contactors are electrically and mechanically interlocked.
VFD with NEMA 3R (A) Bypass Option or VFD only The NEMA Type 3R Bypasses are companion packages for the family of SED2 Variable Frequency Drives. NEMA Type 3R enclosed bypasses are manufactured for outdoor locations. The 3R rating provides a degree of protection to the enclosed SED2 VFD and electrical control components. A heater is supplied to protect against condensation.
