LS Electric LSLV0055SP100-2CEND Inverter VFD Low Voltage Drive

Description

LS Electric LSLV0055SP100-2CEND

A 7.5 HP (5.5 kW) SP100-series inverter for 3Φ 200–240 VAC, designed for HVAC and pump applications. It includes an internal contactor bypass for no-down-time operation, compact NEMA-1 enclosure, and slip-compensated V/F motor control. Key features include the integrated bypass, built-in DC reactor, and support for BACnet/Metasys/Modbus communications.

The Polar Energy Assessment:

This SP100 drive is tailored for HVAC fan/pump control requiring continuous operation. It delivers 5 HP heavy-duty or 7.5 HP normal-duty output at 240 VAC input, with slip-compensated V/F control and a built-in DC reactor for harmonic reduction. Its auto-bypass function (HAND/OFF/AUTO) enables maintenance without shutting down the system. The drive’s high short-circuit rating (100 kA) makes it robust in typical panels. Strengths include the integrated bypass and communications, compact design, and comprehensive motor protection. Trade-offs are its indoor-only NEMA 1 enclosure (UL Type 1) and the lack of a built-in EMC filter (requiring external filtering for noise-sensitive installations). It is fixed at 3Φ 240 VAC input (no single-phase) and supports only V/F control (no vector mode). Like all SP100 models it is rated for –10–50 °C (HD) ambient

Pros

• Integrated 3-contactor bypass for uninterrupted operation
• Built-in DC reactor (standard) for reduced harmonics
• Compact NEMA-1 (indoor) enclosure easy to retrofit
• Supports BACnet, Metasys and Modbus protocols (built-in)
• High SCCR (100 kA per IEC 60439-1) for robust fault clearance

Limitations

• No built-in EMC filter (external filter needed for strict EMC requirements)
• Indoor use only (UL Type 1 enclosure)
• Fixed 3Φ 240 VAC input (no single-phase option)
• Only V/F control method (no high-performance vector control)

Typical use cases

Ideal for HVAC and pump systems in commercial buildings. Examples include:

• HVAC fans and pumps (e.g. air handlers, chillers) where maintenance bypass is critical
• Building automation systems requiring integrated drive communication (BACnet/Metasys) for fan/pump control
• Retrofit VFD installations in 200–240 VAC motor control panels, simplifying upgrades of existing fans/pumps.
