While designing a woodworking workshop, particularly where there is limited three-phase power access, it is important to choose the correct phase converter. One of our customers in Oregon contacted us last month with one particular requirement: powering a 7.5 HP computerized table saw. 

Today, we will discuss how our team helped the customer and provide you with beneficial insights so you too can solve the similar issue if you came across one. 

Understanding the Equipment

The table saw of the customer, although not a full CNC machine, has computerized aspects like automatic lifts and programmable blade height. These aspects require a stable and balanced supply of power so that it functions optimally and lasts long.

The Importance of Voltage Balance

Electronic hardware is vulnerable to voltage fluctuations. Subtle variations would cause malfunctioning or decreased productivity. The buyer stressed the condition of the original manufacturer for having a voltage tolerance of not greater than ±0.05%. Our phase converters are built to provide tightly phased voltage, which allows such equipment to run to its designated parameters.

Selecting the Right Phase Converter 

We suggested a 15 HP phase converter, given that the table saw has a 7.5 rating. This will allow the converter to accept the load easily with adequate voltage stability. We considered two models:

  • PL Series: With a built-in start/stop button and safety features, this model provides added convenience and safety.

  • NL Series: A simpler model without the built-in controls, appropriate for applications where automatic restart upon power loss is required.

Here is a video for comparison between these two series. 

For the customer's use, the PL Series was more suited because of its protective qualities and manual control, as computerized equipment demanded.

Installation and Specifications

The 15 HP PL Series phase converter consists of two primary components: 

  1. Generator: The cast iron, weighing approximately 278 pounds, totally enclosed fan-cooled (TEFC) generator provides solidity and resistance to dust, an important consideration in woodworking facilities.

  2. Control Panel: With a weight of about 32 pounds, the panel contains the start/stop controls and protection circuitry.

The total weight and sturdy construction highlight the industrial-grade nature of the equipment.

Shipping and Support

The generator was shipped from our Reno warehouse for the Oregon-based customer, while the control panel was dispatched from Phoenix. We charged a flat rate of $180 for shipping, and there were no extra taxes for residents of Oregon. The delivery usually takes 3-4 business days.

In addition, we ensure our products with a lifetime warranty against manufacturing defects. If there are any problems, our customer support team is at your service for troubleshooting and replacement.

Final Thoughts

Choosing the proper phase converter is critical to the smooth running of computerized woodworking machinery. Our experience with the Oregon customer underscores the need to know what equipment specifications are and ensure that the selected converter is compatible with the needs. With a proper setup, woodworkers can enjoy precision, efficiency, and durability in their work.
