When you are sorting through VFDs, soft starters, and other motor controls, the first fork in the road is whether your load needs a gentle AC ramp-up or adjustable DC speed. This head-to-head puts the Stellar SR22-09 soft starter against the Industrial Grade PWM DC motor controller so you can match the right tool to your voltage and current needs.
Quick verdict
If you need a 480V AC soft starter with a 9 FLA rating, the SR22-09 is the specialized industrial choice. If you need a new, lower-priced controller for a DC brush motor in the 10V-50V range, the Industrial Grade PWM DC motor controller is the flexible option for that job.
At a glance
The table below highlights the main differences between the two motor controls.
| Feature | SR22-09 Stellar Soft Starter | Industrial Grade PWM DC Motor Controller |
| Price | USD 94.99 | USD 74.99 |
| Product type | Soft starter | PWM DC motor controller |
| Input voltage | 480V AC | 10V-50V DC |
| Rated current | 9 FLA | 60A rated (100A max) |
| Condition | Used | New |
| Country of Origin | United Kingdom | China |
| Included extras | - | Potentiometer, safety fuse & switch |
The two units are separated by a $20 spread, with the PWM controller at the lower end.
Where each product wins
The SR22-09 wins for anyone working with a 480V AC motor control line. It is a purpose-built soft starter rated at 9 FLA, and the used condition is the main tradeoff.
The PWM controller wins for DC brush motor work between 10V and 50V. It is new, rated at 60A with a 100A max, and includes a potentiometer, safety fuse and switch, a CW/CCW switch, and a cooling fan. It sits at the lower end of the price spread, but it cannot cross over to 480V AC duty.
Product notes
SR22-09 Stellar Soft Starter
This is a used Stellar SR22-09 soft starter built around a specific industrial need: 480V AC input and a 9 FLA load rating. If your motor's full-load current is in that range, the SR22-09 gives you a soft starter designed for that job rather than a generic speed controller. The model designation points to the same SR22-09 unit, so you can match it against your panel's requirements. The main limitation is the used condition; you are buying a pre-owned component, not a fresh unit. With a listed input of 480V AC, this unit is aimed at that specific line-voltage application.
Industrial Grade PWM DC Motor Controller
The PWM controller is a new option for DC brush motors in the 10V-50V range. It carries a 60A rated current with a 100A max, and the included potentiometer gives you a 0%-100% speed range. A CW/CCW switch lets you change rotation direction, and the cooling fan helps keep things stable during longer runs. The safety fuse and switch are part of the package, which simplifies wiring. The clear limitation is the DC-only focus: this controller will not replace a 480V AC soft starter, and its 10V-50V input window means it is built for low-voltage DC systems, not industrial AC line voltage.
Final choice by use case
- Choose the SR22-09 Stellar Soft Starter at USD 94.99 when your application calls for a 480V AC soft start at 9 FLA and you can accept a used unit.
- Choose the Industrial Grade PWM DC Motor Controller at USD 74.99 when you need a new, lower-priced controller for a DC brush motor running on 10V-50V DC at up to 60A rated current.
- If you are still undecided, let your motor decide: AC power and a soft-start profile point to the SR22-09; DC brush speed control points to the PWM unit.
