Overview
Product and Purpose
PowerGuard PDU-R2D4 is a 2U, 19-inch rack-mount power distribution unit for military and industrial systems operating in harsh environments. It supports mains and UPS inputs together to deliver uninterrupted, safe power distribution.
Its remote management lets operators monitor all input and output lines, internal temperature and humidity, and system status in real time. With the Windows 10 compatible interface, outputs can be switched individually or in groups, restarted, and connected devices can be pinged.
Engineering Capability
Power input and outputs:
| Feature | Value |
|---|---|
| Input voltage | 180–240 VAC, 50 Hz, single phase |
| Input type | 1 × mains + 1 × UPS, separate connectors |
| Outputs | 8 AC + 2 DC |
| Output voltage and current | Configured per project (nominally 220 VAC / 24 VDC) |
| AC/DC converters | At least 2, with independent protection and distribution |
| Efficiency | ≥ 85% |
Protection and safety:
- Over / undervoltage protection on the inputs, overcurrent and short-circuit protection on the outputs
- Thermal protection for internal components

- Physical emergency stop and bypass buttons on the front panel
- LED status indicator and illuminated control button for every output
Control, communication and monitoring:
- Ethernet (100 Mbps) and RS-422 communication
- Windows 10 compatible remote management software: output control, system health, temperature / humidity monitoring, ping
- Outputs can be switched individually, in groups or in sequence; output scenarios are configured in software
- Integrated internal temperature and humidity sensor
Mechanical and environmental:

Standards: MIL-STD-810G (environmental), ISO 9001 (quality management), IPC-A-610 Class 3 (high-reliability electronic assembly), J-STD-001B (soldering), IPC/WHMA-A-620 (cable and harness assembly).
Typical Applications
- Military electronic systems: Uninterrupted, stable power for radar, command-and-control and weapon systems
- Land platforms: Rack-mount power distribution on armoured vehicles, tactical wheeled vehicles and mobile systems
- Naval platforms: Power distribution for sonar, radar and communication systems
- Shelters and fixed operating sites: Remotely managed supply for mission equipment in rack cabinets
- Test and calibration systems: Stable, monitored power for sensitive equipment
The TEDEG Advantage
PDU-R2D4 combines mains + UPS dual input, AC and DC outputs, surge-protected inputs and remote management in a single 2U rack unit. Because output scenarios are configured in software, integrators can set up different load plans on each project without changing hardware.
For rack applications that need more sources and outputs see PDU-RT5002; for outdoor distribution see the MAR-2 Power Distribution Panel.
Corporate assurance: TEDEG Defence is an approved supplier of ASELSAN, Roketsan and the Turkish Ministry of National Defence (MSB), with NATO supplier registration under NCAGE: TM885.

FAQ
What sources does PDU-R2D4 run from?+
It runs from single-phase 180–240 VAC, 50 Hz and accepts one mains and one UPS input through separate connectors, so loads stay powered from the UPS line when mains power fails.
How many outputs does it have, and at what voltages?+
There are 8 AC and 2 DC outputs. Output voltage and current are configured per project and can nominally be 220 VAC and 24 VDC. The DC outputs are fed by at least two independent AC/DC converters.
How is it managed remotely?+
It communicates over Ethernet (100 Mbps) and RS-422. With the Windows 10 compatible software, outputs can be switched individually, in groups or in sequence; voltage, current, temperature and humidity are monitored live, and connected devices can be pinged.
What protection does it have?+
Over / undervoltage protection on the input, overcurrent and short-circuit protection on the outputs, and thermal protection for internal components. The input line has a surge arrester with LED status, and the front panel has emergency stop and bypass buttons.
What environmental conditions does it operate in?+
It operates at −30 °C … +50 °C and 5–95% non-condensing humidity. The EMI/EMC-protected aluminium chassis and gasket are designed against vibration, shock and electromagnetic effects, and the 10 kg unit travels to the field in a military-grade hard case.
