Why Glentek Amplifiers Are Critical for Your Fadal CNC

 If you’ve been around CNC machines long enough—especially Fadal VMCs—you already know how important the amplifier is to the overall performance of the system. But not all amplifiers are made the same. The reliability, safety, and precision of your machine often come down to one small but powerful component: the amplifier. And when it comes to long-lasting, intelligently designed options, Glentek Amplifiers stand out for all the right reasons.

What Sets Glentek Amplifiers Apart

Whether you have a shop with high traffic or are handling a few machines in-house, downtime is expensive. The amplifier controls axis motor movement, so even a small failure can cause significant disruption. That's why selecting a quality, well-supported amplifier is a smart choice—not a repair choice.

At ITS CNC, we supply the ITS Fadal DC Brush Amplifier (AMP-0021-ITS)—a direct equivalent of Glentek AMP-0021 as well as AMC AMP-0015 models. But we don't offer it just for sale.

Why ITS CNC's Glentek-Compatible Amplifier is a Better Alternative

Here's the difference our version makes:

• Motor Short Protection:

Internal protection against damage in the event of a short in a motor or wiring. Rather than catastrophic failure, the amp safely shuts down.

• Enhanced Fault Management:

Our amplifiers don't leave you in the dark when something is amiss. It provides feedback—a clear indication that you're in maximum output mode, that it has folded back, or that there's an actual fault.

• Increased Servo Responsiveness:

With 2x faster servo loops, you'll appreciate enhanced accuracy in motion and more uniform zero-speed stiffness.

Tiny things such as loose metal shavings in the cabinet can do tremendous amounts of harm. Our amps have built-in protection shielding.

Complete Engineering Support – You're Not Simply Purchasing a Part in a Box

The real difference is the support you get. Our staff does not merely sell parts—they knows them. We have worked with Glentek engineers, AMC engineers, and Varedan engineers to make our solutions address actual issues in CNC environments.

Here's what we provide:

• Diagnosis Support: 

Need help determining if the amplifier is the actual problem? We can help you out.

• Clear Installation Documentation: 

Easy-to-understand, step-by-step instructions along with tips for maintaining.

• Post-Installation Support: 

We're here even after you buy from us, ready to help in case anything goes wrong.

• 1-Year Warranty: 

Guaranteed peace of mind.

Why Settle for Less?

The axis amplifier is among the most important parts of your Fadal CNC machine. If it breaks down, the whole machine is offline. That's why more CNC experts are making the change to Glentek Amplifiers or top-quality alternatives such as the AMP-0021-ITS from ITS CNC.

If what you need is a solid upgrade, supported by engineering know-how and a company that actually cares—this is your signal to stop settling and begin upgrading.
