How It Works

The PowerGuard TPS-28 Power Management Module, developed by TEDEG Defense, is an intelligent, modular, and military-standard-compliant power management system.
The device receives a 230 VAC mains input, converts it into isolated and stable 28V DC outputs, and simultaneously manages the distribution, monitoring, and control of these outputs.
As a result, the PowerGuard TPS-28 operates not only as an AC-DC power converter but also as a comprehensive energy management platform.

Input Stage – High-Efficiency AC to DC Power Conversion

The system accepts a 230 VAC ±10% mains or generator input.
With its universal input range (90–264 VAC), it operates seamlessly in both civil and military power infrastructures.
This input energy is converted into 28V DC through high-efficiency isolated converters.

During the conversion process, the PowerGuard TPS-28:

• Provides greater than 90% power conversion efficiency.
• Delivers clean and stable energy with low ripple (maximum 150 mVp-p).
• Ensures full electrical isolation for safety and noise reduction.

This guarantees stable, low-noise power delivery to sensitive electronic systems such as communication units, radar components, and control electronics.

Distribution Stage – Modular Power Management

The PowerGuard TPS-28 is built around three main power modules:

• Module 1: 28V / 50A (4 × 10A + 1 × 50A)
• Module 2: 28V / 10A (4 × 2A + 1 × 10A)
• Module 3: 28V / 10A (4 × 2A + 1 × 10A)

Each module is individually isolated, and every output channel can be independently controlled.
Through the RS-485 HD communication interface, the user can remotely turn channels on or off, set current limits, and monitor real-time voltage and current values for each output.

Unlike traditional power supplies, this modular design enables centralized power management within a single system, allowing multiple devices to be managed independently through one platform.

Control Stage – MCU-Based Intelligent Operation

At the core of the PowerGuard TPS-28 lies an MCU-based central control board, which continuously oversees system operation.
This control unit performs an automatic Built-In Test (BIT) twice per second and collects real-time diagnostic data from each output channel.

In the event of a fault, overcurrent, or overtemperature condition, the system:

• Automatically shuts down the affected output.
• Triggers a Power OK alarm output to notify the user.
• Reports the incident via the RS-485 communication interface.

Through this self-monitoring and self-protecting structure, the PowerGuard TPS-28 ensures uninterrupted and reliable operation, allowing potential faults to be detected and addressed proactively.

Cooling Stage – Passive, Silent, and Reliable Operation

One of the most advanced aspects of the PowerGuard TPS-28’s operation is its completely passive cooling system.
