DC24V Power Supply 100W With Active PFC

1. Input Characteristics

Rated Voltage (100~240V AC): This is a wide-voltage input power supply, capable of operating normally under the mains voltage in most parts of the world without manual switching.

Range (90~264V AC): It can operate stably even in areas with unstable voltage (such as low or high voltage), demonstrating strong adaptability.

Input Current (1.5A): At the lowest input voltage (90V), the maximum input current is approximately 1.5A, used to calculate the specifications of upstream circuit breakers and conductors.

Frequency (50/60Hz): Compatible with major global mains frequencies.

Efficiency (85% @230Vac): The efficiency is at a mainstream level (80% is the standard for 80 Plus White). This means that at full load output, approximately 15W of power will be dissipated as heat. For a 100W power supply, this heat generation requires adequate chassis ventilation.

Power Factor (PF>0.9/0.95): A high PF value indicates low "pollution" to the power grid, representing energy conservation and environmental protection, and also reducing interference to other equipment on the same line.

Inrush Current (Cold Start 15A/230V): At the moment of power-on, the current will have a very high peak value (15A). This value is within a reasonable range, but for scenarios with frequent power-on and power-off, the impact on contactors or switches needs to be considered.

Leakage Current (<0.5mA): Very safe, far below levels that could harm the human body.

2. Output Characteristics (Implicit)
Rated Output: DC 24V, 100W. Calculated rated output current is approximately 4.17A (100W / 24V).

Load Type Matching:

Fan: Typically an inductive load, there may be a slightly large current at startup. This power supply's overload protection range (105-180%) can well withstand the fan's starting current without falsely triggering the protection. Relays: These are inductive loads and generate a back electromotive force when disconnected. The power supply's output capacitor can absorb some of this energy, usually without causing problems.

3. Protection Features - Key for Industrial Applications

Output Overload Protection (105~180%): The power supply activates overload protection when the output power is between 105W and 180W. This is a range, not a fixed value, providing flexibility and preventing power outages due to small instantaneous peak currents (such as motor starting).

Output Short Circuit Protection (Hiccup Type): Ideal for this application. If a short circuit is caused by incorrect wiring or a load fault, the power supply enters a "hiccup" mode-continuously attempting to restart. Once the short circuit is cleared, the power supply automatically resumes normal operation without manual intervention. This is crucial for unattended equipment.

4. Environmental Parameters - Reflecting Industrial-Grade Quality

Operating Temperature (-20~60℃): Wide range, adaptable to most industrial environments, including cold workshops without heating or the interior of equipment with high heat output.

Humidity (10~90% RH, non-condensing): Good tolerance to humidity, but condensation must be prevented, otherwise it may cause short circuits.

Vibration (2G, 60 minutes): Passed basic vibration testing, indicating that its structure and welding are robust and can withstand vibrations in transportation and general industrial environments.

Temperature Drift (±0.03%/℃): Output voltage will drift slightly with temperature changes. This accuracy is perfectly adequate for powering fans and relays, as their voltage stability requirements are not high.

5. Safety and Regulations

Safety Standards (GB4943-1): Complies with Chinese information technology equipment safety standards, a necessary condition for the product to be sold in the Chinese market.

Withstand Voltage and Insulation: Good isolation strength, effectively protecting downstream loads and operator safety. 6. Physical Dimensions
6.Dimensions: 101.5*54*35mm: This is a compact design, facilitating installation inside the equipment.
