Advantech PSD-A40W24 40W 24V DIN-Rail Power Supply
The Advantech PSD-A40W24 is a compact 40 W DIN-rail power supply that delivers regulated 24 VDC power for industrial control and automation equipment. Its slim housing is suitable for control panels where mounting space is limited, while its wide input range supports machine platforms intended for different electrical environments. Emaconn can assist with current price requests, availability checks, delivery planning, and technical product evaluation.
Output Performance for 24 VDC Systems
The unit provides 24 VDC at a rated current of 1.67 A. Its adjustable range extends from 22 to 27 VDC, enabling controlled voltage setting during commissioning. Any adjustment must remain within the input limits of all connected devices.
A short-duration output of up to 2.5 A is available for approximately three seconds. This peak capacity can help accommodate temporary start-up loads, but the connected equipment must not exceed the continuous 40 W rating during normal operation.
Advantech PSD-A40W24 Key Product Specifications
- Rated output: 24 VDC at 1.67 A
- Output power: 40 W
- Adjustment range: 22 to 27 VDC
- Peak current: 2.5 A for up to three seconds
- Input range: 85 to 264 VAC or 110 to 375 VDC
- Input frequency: 47 to 63 Hz
- Typical efficiency: 89%
- Mounting rail: TS35 in accordance with EN 60715
- Dimensions: 32 × 100 × 90.2 mm
- Connection type: screw terminal
The unit’s 32 mm width supports efficient panel layouts and leaves additional rail space for controllers, protection devices, relays, and terminal blocks. Natural-convection cooling avoids an internal fan, but the cabinet must provide adequate heat dissipation.
Protection and Thermal Management
Integrated protection covers overvoltage, overcurrent, short-circuit, and overtemperature conditions. These functions contribute to system reliability during electrical faults. Correct upstream protection, protective earthing, cable selection, and circuit separation are still required.
The documented operating range is -25°C to 70°C. The applicable product documentation specifies full-load operation up to 60°C, after which output must be derated by 2.5% per degree Celsius. Product revision and derating curves should be checked during detailed engineering.
Application Suitability
The PSD-A40W24 may supply compatible PLC accessories, sensors, interface modules, communication equipment, monitoring systems, relays, and compact industrial controllers. The total connected current should be calculated using the maximum expected demand rather than typical consumption alone.
For maintenance replacement, compare the exact part number, input range, output capacity, adjustment range, housing dimensions, terminal layout, mounting method, and environmental ratings. A higher-wattage or lower-wattage unit should not be substituted without an engineering review.
Ordering Considerations
Technical purchasing teams should confirm the quantity, destination, required delivery date, installation environment, and any mandatory approvals before placing an order. Product availability and lifecycle status can affect whether the original model or an approved alternative is the most practical procurement option.
Supply and Selection Assistance from Emaconn
Emaconn can provide quotation support, international sourcing, stock-status information, expected lead-time evaluation, and alternative-product research. Sharing the existing product label and connected-load information can help reduce selection errors in replacement projects.
When an alternative is considered, Emaconn can support comparison of voltage, current capacity, input range, physical dimensions, mounting, protection, efficiency, environmental performance, and required certifications. Additional Advantech industrial automation products may also be evaluated within a consolidated procurement request.
Advantech PSD-A40W24 Frequently Asked Questions
What is the output rating of the PSD-A40W24?
It supplies 24 VDC at 1.67 A, providing a total rated output of 40 W.
What is the adjustable output range?
The output voltage can be adjusted between 22 and 27 VDC.
Does it support a temporary power boost?
Yes. It can provide up to 2.5 A for approximately three seconds.
What input voltage does it accept?
It accepts 85 to 264 VAC or 110 to 375 VDC input.
How wide is the housing?
The housing is 32 mm wide, making it suitable for compact DIN-rail layouts.
Can it power industrial sensors and relays?
Yes, if they operate at 24 VDC and their combined continuous and peak current remains within the supply limits.
Does high ambient temperature reduce available output?
Yes. Output derating applies above the documented full-load temperature threshold.
How can stock availability be checked?
Contact Emaconn with the exact part number and quantity for current availability information.
Can a volume quotation be requested?
Yes. Emaconn can evaluate project quantities, destination, required schedule, and sourcing conditions.
What must be verified before choosing an equivalent model?
Verify output voltage, current, peak capacity, input range, dimensions, mounting, terminals, protection functions, environmental limits, and certifications.
