Napájací zdroj PLANET PWR-40-24, 40 W, 24 V výstup, 100–240 V AC vstup, pasívne chladenie, LED stav

PLANET PWR-40-24 is a compact 40 W power supply unit that provides a regulated 24 V DC output from a universal 100–240 V AC input at 50–60 Hz. Designed with passive cooling and a visible power LED indicator, this unit complies with UL508 and TUV EN60950-1 safety standards. Its small footprint (40 × 100 × 90 mm) and rugged design make it suitable for industrial and networking equipment, embedded systems, and installations requiring reliable low-voltage DC power.

Advantages

The power supply’s compact dimensions and DIN-rail compatible design enable installation in confined control cabinets and communication racks where space is limited. Passive cooling eliminates fans and moving parts, reducing maintenance and audible noise while increasing reliability in dusty or vibration-prone environments. Built-in protections for short circuit, overload, over-voltage and over-temperature ensure stable operation of connected equipment. A front-panel LED provides quick visual confirmation of power status.

Suitable for

• Industrial Ethernet switches and media converters
• Embedded controllers and single-board computers
• Control cabinets and automation panels
• Small network installations and access points
• Field devices in harsh or vibration-prone locations

Key specifications

• Output power: 40 W
• Output voltage: 24 V DC
• Input voltage range: 100–240 V AC, 50–60 Hz
• Cooling method: passive (free air convection)
• Status indicator: power LED
• Operating temperature range (typical design capability): designed to operate in wide temperature environments
• Dimensions (W × D × H): 40 × 100 × 90 mm
• Safety standards: UL508 and TUV EN60950-1 compliant

How to use

Mount the unit on an appropriate DIN rail or secure it according to the installation requirements, ensuring adequate ventilation around the device for free air convection. Connect the AC input to a properly rated 100–240 V AC power source with correct grounding. Connect the 24 V DC output to the load, observing correct polarity and the total current draw not to exceed the 40 W rating. Verify the LED indicator to confirm normal operation and follow local electrical codes and safety procedures when wiring.

Recommendations

Install the power supply in an environment free from excessive dust, corrosive gases or direct water exposure. Allow clearance above and below the unit for natural convection. If loads approach the maximum rating, verify ambient temperature conditions and derating requirements. Periodically inspect connections and the LED status to ensure continued reliable operation.
