Product Description
The USB-C-3A (Ultrathin 8.8mm 11V-28V DIN Rail USB C power supply) is a 11 V to 28V input 3A DIN Rail buck converter providing low ripple constant voltage output for USB C devices. It’s intended use are tight control cabinets, to supply usb devices with voltage. A green power good LED indicates the presence of an output voltage. The device is resilient to typical operating failures: Input reverse polarity, output short circuit, open circuit, moderate input transients and moderate output transients.
The device offers solid output current stability over the complete input voltage range. The device may be operated at ambient temperatures between -40°C und 50°C.

Fixed 5 V — no USB-PD negotiation (the datasheet describes a buck converter, no PD controller). Output is 5 V (min 5.0, typ 5.15, max 5.3 V) rated to 3 A total across the USB-C port and the screw terminals. Need 9 V or 12 V PD? Pick the USB-AC-PD or USB-DC-PD.
11–28 V DC. The specification table guarantees 11 V as the minimum and 28 V as the maximum input voltage. The datasheet's headline, feature summary and pinout quote 10 V, so design for 11 V and treat anything below as outside the specification.
95 % peak, around 0.75–1 A output. Efficiency stays above 90 % across the full 0–3 A load range. At very light loads the IC enters pulse-skipping mode, which reduces switching losses but increases ripple slightly (~75 mV pk-pk near no-load, falling to ~30 mV above 0.5 A).
The datasheet states no EMC emission class for the USB-C-3A, so we do not claim one. Figure 7 plots conducted emissions on the input and output lines against the CISPR 32 Class A and Class B limits across 0.15–30 MHz at full load; it is a measurement plot, not a compliance statement. If your installation requires a specific class, for example in a residential environment, contact DPS first. The applied engineering standards listed in the datasheet include IEC 61000-4-2 through -4-8 for immunity.
Tolerates up to -28 V DC reverse on the input without damage. An input reverse-polarity MOSFET and an input TVS diode (1SMA4751A) handle protection; an output TVS (1SMA4734A) additionally clamps output transients.
8.8 mm DIN-rail width. The datasheet lists dimensions as 8.8 × 88.4 × 58 mm (L×W×H per the spec-table header, with the feature summary calling out the 8.8 mm rail width). Footprint compatibility with the USB-DC-PD isn't stated in this datasheet — confirm in the USB-DC-PD datasheet before assuming drop-in interchangeability.
Yes — DPS customises output voltage, output current rating, and input voltage range for production volumes. An engineering fee applies; contact DPS to scope your variant.
