Power supply MEAN WELL RSP-320-4, AC 88–264 V input, 4 V output, 320 W, RoHS, 115×215×30 mm

The MEAN WELL RSP-320-4 is an enclosed AC-DC power supply delivering 4 V DC at up to 60 A with a total output power of 320 W. It accepts a wide AC input range of 88–264 V and uses forced-air cooling in a 1U low-profile metal housing (115×215×30 mm). The unit is RoHS compliant and is designed for industrial and automation applications where compact, reliable DC power is required.

Advantages

The RSP-320-4 provides a single, stable 4 V output with high current capacity (60 A) and active PFC for improved power factor and efficiency. Its compact 1U low-profile design and forced-air cooling allow installation in control cabinets and machinery with limited space. RoHS certification ensures compliance with environmental standards, and the enclosed construction offers protection in industrial environments.

Suitable for

• Industrial automation equipment
• Control cabinets and switchgear
• Embedded systems and power distribution for low-voltage devices
• Machines and production lines requiring 4 V DC at high current

How to use

Install the RSP-320-4 inside a suitably ventilated control cabinet or equipment enclosure, ensuring the forced-air path is not obstructed. Connect the AC input to an appropriate mains source within 88–264 V AC and verify grounding. Wire the 4 V DC output to the load using conductors rated for 60 A, observing polarity. Follow MEAN WELL installation instructions and secure the supply mechanically to prevent vibration or movement during operation.

Recommendations

Use appropriate fusing and cable cross-sections for 60 A output currents, maintain adequate ventilation for forced-air cooling, and perform periodic inspections of connections. For integration into safety-critical systems, follow local electrical codes and MEAN WELL application notes.
