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.

If you need AC at frequencies other than 50 Hz, see Frequency Converters, Motor Drives & Military UPS Systems.
