Vero Power Trivolt PK 120 / PF 116-010078G EPLAXSubrack Modules Power SUPPLY

The Vero Power Trivolt PK 120 is a robust, modular power supply unit designed for 19-inch subrack systems. Its key feature is the “Trivolt” input, meaning it can automatically accept a wide range of AC input voltages without needing a manual switch. This makes it ideal for use in various countries and unstable power environments.

The code PF 116-010078G EPLAX is likely a specific manufacturer’s part number or a designation for a particular configuration kit (e.g., the PSU plus specific plug-in modules).

Detailed Breakdown of the Product Name:

1. Vero Power: The brand, part of the larger Verotec group (now often associated with Artesyn Embedded Technologies or similar industrial power brands). This brand is known for reliable power solutions for embedded computing and industrial applications.

2. Trivolt: This is the key feature. It indicates a wide-range, automatic-selecting AC input. Typically, this covers:

   • 100-120V AC

   • 200-240V AC

   • And sometimes a wider range like 85-264V AC.

   • The unit automatically detects and adjusts, eliminating the need for a physical voltage selector switch.

3. PK 120 / PF 116: These are the model series codes.

   • PK 120 likely refers to the main power supply chassis or the base unit with a specific power rating (e.g., 120W capable).

   • PF 116 likely refers to a specific plug-in output module that attaches to the PK 120 base unit. This modularity allows users to customize the output voltages (e.g., +5V, +12V, -12V, +24V, etc.) for their specific application.

4. 010078G: This is a specific manufacturer’s part number or a unique product identifier for this exact configuration (e.g., a PK 120 base unit pre-assembled with a PF 116 module).

5. EPLAX: This is probably the manufacturer’s internal product series name or code for this family of subrack power supplies.

6. Subrack Modules: This confirms the form factor. It is designed to slide into a standard 19-inch equipment rack using a subrack (or card cage) system, like those conforming to the Eurocard standard.

7. Power Supply: The core function of the device – to convert AC mains power (from a wall outlet) into regulated, low-voltage DC power required by the other electronic modules (e.g., CPU boards, I/O cards) in the subrack.

Key Features :

• Wide Input Voltage Range (Trivolt): Automatic operation from ~100V to 240V AC, 47-63 Hz.

• Modular Design: Allows for customization of DC output voltages by swapping plug-in output modules (like the PF 116).

• High Efficiency: Designed for reliable operation with good power conversion efficiency.

• Compact Form Factor: Designed for high-density installations in 19″ subracks.

• Robust & Reliable: Built for 24/7 operation in industrial environments with features like over-voltage and over-current protection.

• Forced Air Cooling: Often includes a built-in fan for heat dissipation.

Typical Applications:

This type of power supply is used in systems that require stable, reliable power for multiple electronic cards. Common applications include:

• Industrial Automation and Control Systems (PLCs, motor controllers)

• Telecommunications Equipment

• Test and Measurement Systems

• Data Acquisition Systems

• Medical Electronics

• Broadcast and Audio/Video Racks
