TRENDnet TI-RSP100048, 1000W, 48V DC, 21A AC to DC Industrial Power Supply with PFC Function

The TRENDnet TI-RSP100048 is a rugged, high-performance AC-to-DC power supply designed to keep critical industrial devices powered reliably. Delivering 48V DC at up to 21A (1008W), it provides ample headroom for network equipment, surveillance systems, and industrial controllers in demanding environments. With a universal 100–240V AC input, 50/60 Hz operation, dual active cooling fans, and a 19" rack-ready form factor, this power supply is built to thrive in manufacturing floors, warehousing facilities, and data centers. The inclusion of a Power Factor Correction (PFC) function further enhances energy efficiency and power quality, helping to minimize electrical stress on the facility’s electrical system while supporting continuous operation around the clock.

• Broad compatibility and efficiency: The TI-RSP100048 accepts 100–240V AC input at 50/60 Hz, enabling seamless worldwide deployment without multiple SKUs. PFC (Power Factor Correction) improves energy efficiency and reduces harmonic distortion in busy electrical environments, helping your facility stay compliant with modern power standards and maintain stable voltage profiles for connected devices.
• Robust DC output for critical devices: With a 48V DC output capable of up to 21A, the unit delivers 1008W of continuous power. This allows powering multiple network switches, IP cameras, sensors, and other 48V DC equipment from a single supply, delivering steady voltage regulation and reliable performance even as loads fluctuate in industrial settings.
• Dual cooling for reliability: Two active cooling fans are designed to maintain safe operating temperatures under heavy load. Effective cooling reduces thermal stress on internal components, minimizes thermal throttling, and helps extend the service life of both the power supply and the devices it powers in hot manufacturing rooms or remote data cabinets.
• Rack-mount ready for scalable deployments: The TI-RSP100048 is engineered for 19" racks and 4U height, making it easy to integrate into existing cabinet ecosystems. When paired with the TI-R4U mounting bracket, it creates a clean, scalable backbone for power distribution in industrial networks, surveillance suites, and enterprise-grade facilities.
• Clear status signaling and rugged build: A dedicated Power LED provides at-a-glance confirmation of operational status, while the rugged enclosure is designed to withstand the rigors of industrial environments, including vibration and dust exposure in manufacturing floors, warehouses, and data center rooms.

How to install TRENDnet TI-RSP100048

• Plan your rack layout and prepare a 19" rack space. Install the TI-R4U mounting bracket into the rack if not already present, ensuring the area around the unit has adequate clearance for airflow.
• Mount the TI-RSP100048 securely in the rack using the TI-R4U bracket, avoiding overtightening that could deform mounting points. Verify alignment and stability before connecting cables.
• Connect the AC input to a suitable 100–240V AC power source. Use properly rated power cables and ensure the power source is switched off during the connection for safety.
• Connect your 48V DC devices to the output terminals. Plan the wiring to minimize voltage drop across long cables and ensure the total current draw does not exceed 21A to maintain stable operation.
• Power on the unit and observe the Power LED for normal operation. Test the connected devices to confirm they power up properly and that the voltage remains within the expected range under typical loads.
• Verify adequate cooling by ensuring air can flow freely around the unit and fans are unobstructed. Schedule routine checks to keep vents clear of dust and debris in dusty industrial environments.
