Advantech PSD-A40W48 40W 48V DIN-Rail Power Supply
The Advantech PSD-A40W48 is a compact 40 W DIN-rail power supply that converts a wide AC or DC input into a regulated 48 VDC output. It is designed for industrial control cabinets, embedded systems, communication equipment, and automation installations that require a space-efficient DC power source. Buyers can contact Emaconn to request current pricing, lifecycle information, availability, and international supply support.
48 VDC Power for Industrial Equipment
The unit provides a nominal output of 48 VDC at 0.84 A. Its output can be adjusted from 46 to 50 VDC, allowing engineers to compensate for voltage drop or meet the requirements of compatible field equipment. The rated 40 W capacity makes the model suitable for moderate control loads rather than high-current machine circuits.
A 150% peak-load capability supports up to 1.25 A for a short period. This can be useful where connected devices produce temporary current demand during start-up. The complete load profile must still be reviewed because the peak rating does not replace correct continuous-load sizing.
Electrical and Mechanical Characteristics
- Rated output: 48 VDC at 0.84 A
- Output power: 40 W
- Adjustment range: 46 to 50 VDC
- Input range: 85 to 264 VAC or 120 to 375 VDC
- Input frequency: 47 to 63 Hz
- Typical efficiency: 86%
- Mounting: TS35 DIN rail in accordance with EN 60715
- Dimensions: 32 × 100 × 90.2 mm
- Connection: screw terminals
- Cooling: natural convection
The 32 mm housing width is particularly relevant when panel space is limited. Natural-convection cooling also avoids the maintenance requirements associated with an internal fan, provided that installation clearances and cabinet ventilation are adequate.
Protection and Operating Conditions
The PSD-A40W48 incorporates overvoltage, overcurrent, short-circuit, and overtemperature protection. These functions help protect the supply and connected equipment during abnormal electrical conditions. Engineers should nevertheless use appropriate upstream protection, grounding, conductor sizing, and cabinet-level coordination.
The specified operating range extends from -25°C to 70°C. Full rated output is available up to 55°C, after which output derating must be considered. Humidity, enclosure temperature, component spacing, and nearby heat-generating equipment should therefore be included in the thermal assessment.
Application and Compatibility Review
This model may be considered for 48 VDC industrial computers, communication devices, remote I/O equipment, monitoring systems, and compatible control electronics. Compatibility depends on more than voltage alone. The continuous current, start-up demand, grounding arrangement, terminal requirements, and environmental conditions must all match the application.
Before replacing an installed supply, verify the existing model number and mechanical envelope. The PSD-A40W48 is identified by Advantech as a phase-out product, so availability and replacement planning should be confirmed before committing it to a new design.
Source the PSD-A40W48 Through Emaconn
Emaconn can assist with price requests, stock checks, lead-time evaluation, and international procurement for the Advantech PSD-A40W48. Technical purchasing teams should include the required quantity, destination country, requested delivery date, and application details when requesting a quotation.
If the original model is unavailable, Emaconn can help evaluate a suitable alternative. Any replacement must be checked for 48 VDC output, current capacity, input range, dimensions, DIN-rail mounting, terminal arrangement, certifications, and thermal performance.
