PowerGuard-D1000 Mil-Spec DC-DC Converter — Regulated 24 VDC / 1 kW from 12 VDC

The PowerGuard-D1000 Mil-Spec DC-DC Converter is a high-reliability power conversion unit developed by TEDEG Defence for demanding military and outdoor environments. It converts a nominal 12 VDC input (10–18 VDC range) into a regulated 24 VDC / 1 kW continuous output and carries full load at +55 °C without derating.

Where 24 V equipment has to run on a vehicle with a 12 V battery system, D1000 creates a stable 24 V bus between the vehicle supply and the mission electronics. Cold-crank and transient protection are built into the input stage, and the input is compatible with a 12 V military vehicle bus to the ISO 7637-2 profile.

The unit has a fully sealed, fanless aluminium enclosure designed for outdoor installation under rain, dust and vibration. Heat is carried through a conduction-cooled baseplate directly into the host system or an external heatsink. With no moving parts, it runs silently and needs far less maintenance.

Output characteristics:

Protection and control:

• Protection functions: Overvoltage (OVP), overcurrent (OCP), short circuit (SCP), overtemperature (OTP) and reverse polarity
• Remote enable/disable: Opto-isolated ON/OFF pin
• Power Good signal: Indicates a stable output within regulation

Optional communication interfaces:

• CAN-Bus (ISO 11898 / J1939): For vehicle integration
• RS-485 (Modbus/RTU): For industrial control networks
• Ethernet (Modbus/TCP or REST): For advanced system monitoring and diagnostics

These interfaces support remote configuration, performance monitoring, fault reporting and firmware updates.

Connectors and mechanical design:

• Power input (CN1): MIL-DTL-38999 Series III, D38999/24WE6PN, 12 AWG
• Power output (CN2): MIL-DTL-38999 Series III, D38999/24WE6SN, 12 AWG
• Optional communication (CN3): PT02E10-6P, 22 AWG (CAN H/L or RS-485 A/B)
• The connectors provide 360° EMI shielding and environmental sealing; keyed configurations prevent input and output cables being mismated.
• Mounting: Directly onto a vehicle frame or system heatsink via the conductive baseplate. Standard EMI filters and bonding points are provided, and pre-terminated harness sets are available on request.
• Main dimensions (mechanical drawing): 220 × 330 × 150 mm, 4 × Ø8.5 mm mounting holes

Environmental resilience:

Remote Commander Control Box (optional): A rugged field accessory that gives operators control without direct access to the unit. It provides remote ON/OFF, fault reset (CIT/Reset) and a Blackout button that instantly disables all outputs. Power, overvoltage, overcurrent and Blackout status are shown on LEDs, with voltage and current on a digital display. The aluminium front plate mounts in a dashboard or rack; the box connects to D1000 over an RS-485 / CAN-Bus line and operates from −32 °C to +55 °C. Cable length is 3 m as standard, with 5–10 m as an option.

• Military and tactical vehicles: Converting 12 V vehicle power into a stable 24 V bus for onboard electronics, communication and weapon systems
• Mobile command and communication units: Supplying radio transceivers, radar, data routers and network control systems
• Field power distribution systems: Integration into outdoor enclosures or shelters to power surveillance and sensor networks
• Unmanned ground and surface platforms (UGV / USV): A compact DC bus converter for autonomous or remotely operated systems
• Industrial and emergency power systems: Wherever silent, fanless, sealed DC power is needed for critical communication or monitoring

D1000 produces 1 kW of 24 V power from a 12 V vehicle bus in a single sealed unit, so 24 V equipment can be fitted to 12 V platforms without reworking the vehicle's electrical system. Cold-crank and transient protection, UVLO, active reverse polarity protection and a replaceable 100 A fuse come as standard on the input side. Delivering 1 kW without derating at +55 °C means the rated capacity holds in hot climates and enclosed vehicle compartments. The optional CAN-Bus (J1939) interface connects the unit straight into the vehicle network.
