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.
Features
• Built-in SBT P1 and JCI N2 (Metasys®)
building automation system protocols for
easy network integration
• Low harmonics design reduces noises and
interference eliminates the need for filters/
reactors in most installations
• Built-in PID for fast and accurate pressure
control
• Pump staging for open loop, constant pres-
sure, and constant flow-type applications
• Multi-level program access
• Belt failure detection with or without an
external sensor
• Service mode for applications requiring
continuous, uninterruptible operation
• Accepts a wide variety of digital and analog
I/O types, including direct Siemens Ni1000
RTD sensor level inputs
• One common interface throughout all
power ranges
• Full form C relay contacts for digital outputs
Options
• LON® Interface
• Modbus® Interface
• BACnet® Interface
• Advanced Operator Panel (AOP) Module
