The Ultimate Guide to the ITS AC Brushless Amplifier Power Supply & Chassis (AMP-0037-ITS)

In the world of precision machining, the heartbeat of your Fadal CNC machine is its motion control system. When a critical component like the amplifier power supply fails, it doesn’t just mean downtime; it means lost revenue and production headaches. Diagnosing and replacing these complex parts can be a daunting task, especially with older models.

That’s where understanding your components becomes critical. Today, we’re taking a deep dive into one of the most essential upgrades for your Fadal: the ITS AC Brushless Amplifier Power Supply & Chassis, specifically the latest model known as AMP-0037-ITS. We’ll explore what it is, why its design is superior, and how it can restore your machine’s reliability and power.

What Exactly is the ITS AC Brushless Amplifier Power Supply & Chassis?

At its core, the ITS AC Brushless Amplifier Power Supply & Chassis is the central power distribution unit for your Fadal’s axis drives. Think of it as the high-power command center. Its primary job is to take the incoming 3-phase AC voltage from your shop’s power and convert it into a stable, high-voltage DC supply—specifically 360V DC. This clean, potent DC power is then delivered to the individual axis amplifiers (X, Y, Z, A, B) that precisely control the movement of your motors.

The 5 Slot AMP Chassis designation is key. It means this single unit is designed to house and power up to five individual axis amplifiers, making it the perfect solution for a standard XYZAB Fadal machining center. This chassis is not just a passive box; it contains the sophisticated circuitry necessary for this crucial AC-to-DC conversion and safe power management.

Compatibility is Key

A significant advantage of the ITS AC Brushless Amplifier Power Supply & Chassis is its broad compatibility. It is engineered to work seamlessly with amplifier modules from major brands, including:

• ITS

• Glentek

• AMC (Advanced Motion Controls)

This flexibility is a huge benefit for maintenance teams. It means you aren’t locked into a single proprietary brand, simplifying sourcing and replacements when necessary.

The Critical Upgrade: Why the Latest Model (AMP-0037-ITS) is a Must-Have

The part number AMP-0037-ITS represents the latest evolution of this component, and it includes a vital safety and reliability feature that older models lack: an integrated contactor connected directly to the machine’s Emergency Stop (E-Stop) circuit.

The Contactor Advantage

Older style AC Power Supplies (like the obsolete PN: ELE-1633) did not have this built-in contactor. Why does this matter? The contactor acts as a master power switch that is controlled by the E-Stop circuit. When you hit the emergency stop button, the contactor instantly and physically disconnects high-power from the amplifiers and motors. This is a critical safety function that protects your machine, your tooling, and your operators by ensuring a complete shutdown of motive power.

Upgrading to the AMP-0037-ITS model means you are not just replacing a part; you are enhancing your machine's fundamental safety architecture. If you are replacing an old ELE-1633 unit, this upgrade is non-negotiable for modern safety standards.

Navigating the Right Part for Your Needs: AMP-0037-ITS vs. Other Kits

ITS has designed its product line to give you the exact solution you need, avoiding unnecessary costs. The AMP-0037-ITS is a specific configuration, and it's important to distinguish it from other available kits:

• AMP-0037-ITS: Amplifier Chassis and 360V DC Power Supply. This is the core unit we’ve been discussing. It includes the chassis frame and the main power supply circuitry. You would choose this if your axis amplifiers are still functional and you’ve diagnosed the problem as a faulty chassis or power supply.

• AMP-0028-ITS: The Complete Package. If you need everything, this is the kit to order. It includes the Power Supply, Chassis, and all the AMPs (the individual XYZAB amplifier cards). This is a complete replacement solution for a major drive system failure.

• AMP-0060-ITS: Power Supply Only. For the seasoned technician who has confirmed that only the internal power supply board within the chassis has failed, this is the most cost-effective option. It allows for a component-level repair of the existing chassis.
