Physical Construction and Component Layout

This ASPRTU258 power supply measures 4.8 inches in length. Its width reaches 3.5 inches with a height of 3.1 inches. The total weight comes to approximately 0.98 pounds. Manufacturers placed 76 discrete components inside this compact metal housing. These components include a DC-DC converter, PWM controller, filter chokes, and protection circuits. The enclosure uses a ventilated design for passive cooling.

Input Flexibility and Output Specifications

ASPRTU258 accepts a nominal 24V DC input voltage source. The acceptable input range spans from 19.2V to 30V DC. This wide range tolerates voltage dips from battery systems. The module outputs a regulated 5V DC at up to 3 amps. Total output power reaches 15 watts continuously. Ripple and noise stay below 50 millivolts peak-to-peak. Therefore, this supply delivers clean power for sensitive logic circuits.

Protection Features and Energy Storage

The power supply includes multiple protection mechanisms for safe operation. Overload protection activates when current exceeds 3.5 amps. Short-circuit protection shuts down the output instantly. Overvoltage protection clamps the output at 6V maximum. For energy storage, the module integrates two 470µF capacitors. A larger 1000µF capacitor sits on the input stage. These capacitors provide 10 milliseconds of hold-up time. Consequently, the ASPRTU258 rides through brief input interruptions smoothly.

Efficiency and Application Use

ASPRTU258 achieves 85% typical efficiency at nominal load. This high efficiency minimizes heat generation inside the enclosure. Mean time between failures reaches 300,000 hours for reliability. You will find this power supply in Schneider PLC systems and control panels. It powers CPU modules, I/O racks, and communication adapters. The unit operates reliably from -20°C to 60°C ambient. For example, it suits outdoor cabinets or cold storage facilities. Therefore, this power supply provides stable DC energy for harsh industrial environments.
