Best for

Reducing inrush current in large three-phase motors (15HP) like compressors or pumps — add the bypass contactor, it's not included.

What is it and what's it for?

A soft starter is different from a VFD: it doesn't regulate speed all the time, it prevents the electrical "jolt" at the moment a large motor starts up — like accelerating a car gradually instead of flooring it from a stop, which would use much more energy and stress the motor.

Real-world use cases

At home

It's not a typical home product, but someone with a large motor in a pool or high-power residential pumping system might need it to avoid electrical jolts on startup.

In a business or workshop

A workshop or plant with a 15HP compressor or pump can prevent the motor's startup from dropping voltage across the whole installation, something that can affect other equipment on the same network.

How to avoid buying the wrong one

  • The manufacturer itself notes it requires a separate bypass contactor (not included) — add that cost before deciding.
  • The manual isn't guaranteed to be in Spanish — if you don't handle technical English, you'll need help for commissioning.
  • Still has no reviews on Amazon — a good technical option on paper, but with no real feedback from other buyers.

The investment takeaway

For large motors, a soft start reduces mechanical and electrical wear from a full-force startup, which translates into less maintenance and less stress on the electrical installation over time — though it's worth adding the bypass contactor to the budget before deciding.

Waveshare RS232/485/422 to Ethernet Gateway (PoE)

RS485/ModbusPoEDIN rail
4.2 · 120 reviews

Supports all three serial standards (RS232/485/422) on one device, so it works for both old instruments with an RS232 port and multi-device RS485 buses. PoE power is a real plus in installations where there's no outlet near the panel — a single Ethernet cable carries both data and power. Confirm whether your Modbus master needs TCP Server or Client mode before buying; the mode is set in software, it doesn't come fixed from the factory.

MOLLOM VFD 1.5kW (2HP) — Single-Phase to Three-Phase 220V

220V 1P→3P2HPCNC
4.1 · 31 reviews

Single-phase input to 220V three-phase output — the typical choice for workshops without a three-phase feed that want to run a 3-phase motor. This is an entry-level model (2HP/1.5kW), meant for spindles and small CNC motors, not large industrial loads. The output range up to 3000Hz is only useful if your specific spindle takes advantage of it — for a standard 60Hz motor it's irrelevant.

VFD 4kW (5HP) Vector Control — 220V 1-Phase/3-Phase

Vector control5HP1P/3P
4.3 · 24 reviews

Has vector control (not just scalar V/F), which holds torque better at low RPM — important if you'll be threading or cutting at reduced speed. At 5HP/4kW it covers larger motors than the entry-level model, and accepts both single-phase and three-phase input, giving flexibility depending on the electrical setup available. Rated up to 26A — confirm your wiring and breakers can handle that current before installing.
