About the 1SU51001
The 1SU51001 is a SP500 drive that is manufactured by Reliance Electric. This drive has specifications of 575 VAC input voltage and is enclosed in a NEMA 1 or chassis enclosure. The horsepower rating is 0.25-1.0 HP. The drive has many customizable parameters which must be set by the user during installation to match the application specific settings needed. The 575V input voltage is not as common as other SP500 drives that take 460VAC or 230VAC. This means that the 1SU51001 has a much lower demand relative to other SP500 drives but also that less available surplus is on the market.
The NEMA 1 case used on the 1SU51001 is quite fragile and often breaks around the corners. This design issue makes the SP500 cover a product in short supply. In order to install the 1SU51001, the user must do the following:
- Enter all application specific parameters
- Adjust all jumpers to the correct position for the application
- Wire the terminal strip as needed for the application
On the whole, the 1SU51001 is a well designed drive but lacks a significant installed base due to the 575V input voltage.
