Description
LS Electric — LSLV0110SP100-4CEFD (SP100 — Packaged Bypass VFD)
Packaged SP100 bypass VFD for 3-phase 380–480 VAC systems. Built-in 3-contactor bypass, DC reactor, and built-in EMC filter (CEFD) for retrofit-friendly HVAC pump and fan applications.
The Polar Energy Assessment:
The LSLV0110SP100-4CEFD is the 15 HP (11 kW) 480 VAC SP100 packaged solution: compact NEMA-1 cabinet, auto/hand/off bypass switching, and built-in EMC filtering to reduce conducted emissions. It’s perfect where continuity of service (bypass) and EMC compliance matter — but remember it’s an indoor NEMA-1 package, so don’t stick it in a mud puddle.
Pros
- Integrated 3-contactor bypass (HAND/OFF/AUTO) for service without downtime.
- Built-in EMC filter (CEFD) and DC reactor reduce conducted emissions and harmonics.
- NEMA-1 packaged cabinet for fast retrofit installs; built-in BAS protocols (Modbus/BACnet/Metasys).
Limitations
- Indoor NEMA-1 (UL Type 1) only; requires enclosure for wet/dusty/outdoor use.
- Packaged cabinet is bulkier than a bare drive if panel space is at a premium.
Typical use cases
- HVAC central plant pumps and rooftop fans that must keep running during maintenance.
- Retrofits of motor control centers where EMC compliance is required.
