Xizi OTIS Elevator Inverter SMART100-LR

Xizi OTIS Elevator Inverter SMART100-LR is used in elevator main drive and frequency conversion control applications.

This product should be understood as an elevator traction drive inverter, not a small PCB board or a door operator controller. It is normally installed in the elevator control cabinet or drive cabinet, where it helps control motor speed, starting response, deceleration, running comfort, and leveling performance.

In the elevator spare parts market, this product may also be searched as:

• Xizi OTIS Elevator Inverter
• Xizi OTIS SMART100-LR Inverter
• SMART100-LR Elevator Inverter
• Elevator Frequency Converter
• Elevator Traction Inverter
• Elevator Main Drive Inverter
• Xizi OTIS Elevator Drive
• SMART100-LR Elevator VVVF Drive

The main model reference for this page is:

• SMART100-LR

Common power and model references may include:

• SMART100-LR-4007-H3 7.5kW
• SMART100-LR-4011-H3 11kW
• SMART100-LR-4015-H3 15kW
• SMART100-LR4015-H3
• 100-LR-4007-H3

These references are useful for product search and quotation confirmation. However, the final selection should still be confirmed by the old inverter label, motor power, rated current, elevator speed, control system configuration, and cabinet wiring.

Main Drive Position in the Elevator System

SMART100-LR is part of the elevator drive system.

It is different from a door machine inverter, door controller board, or inverter SMART control board. The SMART100-LR inverter is more closely related to the traction motor and elevator running control. If the selected inverter does not match the original drive system, the elevator may have startup problems, running vibration, leveling errors, drive fault codes, or commissioning difficulty after installation.

For this reason, this product should not be selected only by the word “SMART” or by appearance. The complete model number and power rating must be checked before quotation.

Power Rating Should Be Confirmed First

The SMART100-LR series may appear in different power sizes.

For real replacement work, buyers should confirm whether the site needs 7.5kW, 11kW, 15kW, or another power range. A lower-power inverter may not support the original motor load correctly. A higher or different power range may also require parameter adjustment, wiring confirmation, or technician commissioning.

Before ordering, please check:

• Complete SMART100-LR model label
• Power rating, such as 7.5kW, 11kW, or 15kW
• Whether the old label shows 4007-H3, 4011-H3, or 4015-H3
• Motor power and rated current
• Elevator speed and load if available
• Control cabinet photo
• Terminal wiring photo
• Braking resistor or drive cabinet information if available
• Existing inverter fault code or drive fault description

For drive products, an inverter label photo alone is helpful, but motor and cabinet information are also important for accurate matching.

Used in Modernization and Maintenance Supply

Xizi OTIS SMART100-LR inverters are often requested in elevator maintenance, repair, and modernization projects.

In overseas markets such as the Middle East, South America, and Europe, buyers usually care about three things when selecting elevator inverters: correct power matching, stable running performance, and easier replacement confirmation. The SMART100-LR series is suitable for pages targeting buyers who search by old inverter model, power size, or Xizi OTIS elevator drive reference.

This product is also useful for spare parts suppliers because many customers do not simply ask for “an elevator inverter.” They often send a label photo showing SMART100-LR-4007-H3, SMART100-LR-4011-H3, or SMART100-LR-4015-H3 and need a matching replacement.

Site Faults That May Lead to Inverter Replacement

Maintenance teams may inspect the elevator inverter when the site has problems such as:

• elevator cannot start normally
• inverter fault after power-on
• abnormal acceleration or deceleration
• unstable running response
• leveling accuracy problem
• drive communication fault
• motor control signal abnormality
• visible damage inside the drive unit
• repeated inverter alarm during operation

These symptoms may not always be caused by the inverter itself. The motor, encoder or PG feedback, brake circuit, braking resistor, power supply, cabinet cooling, wiring terminals, and control board signals should also be checked before confirming the inverter fault.

Replacement and Commissioning Notes

Do not replace SMART100-LR only by housing appearance.

Elevator inverters may have similar outer size, but the power rating, parameter setting, software version, control signal definition, and drive cabinet wiring may be different. After replacement, technicians may need to check motor parameters, encoder feedback, braking response, running direction, acceleration curve, deceleration curve, and leveling performance.

If the original inverter was damaged by unstable power, motor short circuit, cabinet overheating, braking resistor failure, moisture, or external wiring problems, replacing only the inverter may not fully solve the fault.

For overseas buyers, sending clear photos of the original SMART100-LR inverter label, motor nameplate, terminal wiring, and control cabinet position is the safest way to confirm the correct replacement before shipment.
