AC-DC & DC-DC Power Converters
Stable military power from the grid, a generator or the battery
Most military loads need a stable DC voltage: 24 VDC, 28 VDC, or several levels on the same platform. The converters in this category turn grid, generator or vehicle battery power into those voltages. Their fanless, sealed construction is designed for maintenance-free operation under dust, water and vibration.

About AC-DC & DC-DC Power Converters
Which converter for which need?
- Multi-level DC and 120/220 VAC from a 24 VDC vehicle bus: PowerGuard TPS-24DCAC — 16–28 VDC input, 12/24/28/36 VDC + pure sine AC, 3400 W, BLACKOUT mode
- Isolated 28 VDC from 230 VAC with per-channel current management: PowerGuard TPS-28 — 50 A / 10 A / 2 A switchable outputs, RS-485
- 28 VDC from three-phase 380 VAC: PowerGuard-A 380 — 1–4 kW
- 24 VDC from single-phase AC, including 400 Hz input: PowerGuard-A1000 — 45–420 Hz input, 1 kW, active PFC
- 24 VDC from a 12 VDC vehicle bus: PowerGuard-D1000 — 1 kW, η ≥ 90%, fanless
What to check when choosing a converter: input source (single phase, three phase, vehicle DC), output voltage and number of outputs, continuous power, isolation needs, cooling method and communication interface.

FAQ
Which converter should I choose for my input source?+
For multi-level DC and AC from a 16–28 VDC vehicle bus, the PowerGuard TPS-24DCAC: 12 / 24 / 28 / 36 VDC (10 A each) + 120 VAC and 220 VAC pure sine, 3400 W in total, and a BLACKOUT mode that extinguishes all panel LEDs with one switch. For 24 VDC from a 12 VDC vehicle bus, the PowerGuard-D1000: 10–18 VDC input, 24 VDC / 1 kW, fanless. For 24 VDC from single-phase AC, the PowerGuard-A1000: 45–420 Hz input, 24 VDC / 1 kW, active PFC. To distribute isolated 28 VDC from 230 VAC through individually switched outputs, the PowerGuard TPS-28: 50 A, 10 A and 2 A outputs, ≈1.7 kW, RS-485 HD. For 28 VDC from three-phase 360–440 VAC, the PowerGuard-A 380: 1 / 2 / 3 / 4 kW, IP67, fanless.
Is there an AC-DC converter that can run from a 400 Hz supply?+
Yes. The PowerGuard-A1000 has an input frequency range of 45–420 Hz, so the same unit is used on 50/60 Hz mains and on 400 Hz military power systems. The power factor is ≥ 0.99 at 50/60 Hz but typically falls to 0.75–0.8 at 400 Hz; allow for this when sizing fuses, cabling and EMI filters. The PowerGuard-A 380 is specified for 47–63 Hz and the TPS-28 for 50 Hz (90–264 VAC universal input); these two units are not specified for a 400 Hz input.
How do the converters communicate with my system, and which control signals do they provide?+
The TPS-28 reports the voltage and current of every converter and output over RS-485 HD; each output is switched individually, and there is a Remote ON/OFF input and a Power OK alarm output. On the PowerGuard-A 380, Ethernet (TCP/UDP), RS-485 (Modbus) or CAN-Bus (J1939 / CANopen-style) interfaces are optional, and output sequencing, soft-start and delay parameters are programmed through them. The PowerGuard-A1000 and D1000 come with an opto-isolated Remote ON/OFF input and a Power-Good (DC-OK) signal as standard (the A1000 also has a fault/alarm signal); a CAN-Bus, RS-485 or Ethernet interface and the dashboard-mounted Remote Commander Control Box with a Blackout button are optional. The TPS-24DCAC has no communication interface; it is controlled from the front panel through 10 A thermal breakers, a LED per line and the BLACKOUT switch.
Do the fanless units deliver full power at high temperature?+
The PowerGuard-A1000 (−40 °C … +55 °C) and PowerGuard-D1000 (−32 °C … +55 °C) deliver 1 kW continuous up to +55 °C without derating; heat passes through the conduction-cooled baseplate into the vehicle frame or an external heatsink. The TPS-28 is fanless and operates from −32 °C to +55 °C, the PowerGuard-A 380 is conduction-cooled in an IP67 monolithic aluminium enclosure, and the TPS-24DCAC, the only fan-cooled unit, carries 100% load between −20 °C and +40 °C and runs continuously at +60 °C with the DC-DC modules at 70% and the DC-AC modules at 60%. On the standards side, the datasheets list MIL-STD-810 and MIL-STD-461 with IP67 for the PowerGuard-A1000, MIL-STD-810G and MIL-STD-461 for the D1000 and TPS-28, and MIL-STD-810H shock / vibration profiles and MIL-STD-461 principles for the PowerGuard-A 380; these units are designed to those standards, so state any test report requirement at the quotation stage.
Can the output voltage, power class and connectors be customised?+
The PowerGuard-A Series offers 12 / 24 / 28 / 36 / 48 VDC outputs and 1–4 kW power classes on the same hardware platform. On the TPS-28, total power can be upgraded to 10 kW as required, and the connection is chosen as a MIL-DTL-38999 connector or an industrial terminal block. The D1000 offers an optional ±5% output trim and pre-terminated harness sets on request; on the TPS-24DCAC, alternative output combinations and connector types are configured thanks to the modular architecture. For a wider range, the Mil-Spec AC/DC Converter family is configured from 1 to 10 kW with single-phase or three-phase input and the customer's output voltage (12 / 24 / 28 / 48 V).
What information should I send for a quotation and datasheet?+
Input source (single phase, three phase, vehicle DC), output voltage and number of outputs, continuous power, isolation needs, cooling method and communication interface are enough for a quotation; send them through the quote form. Datasheets are on the product pages: Turkish and English for the TPS-24DCAC and TPS-28, and English for the PowerGuard-A 380, A1000 and D1000.
