Technical Selection Guide: Choosing Enclosed Power Supplies

When designing automation control cabinets, laser CNC machines, 3D printers or commercial LED signage boxes, selecting the right switching power supply series depends heavily on power factor regulations, installation space and cooling requirements:

• LRS Series (15W–600W): Standard 1U low-profile design without active PFC. Highly cost-effective for general industrial machinery, commercial display systems, and enclosed automation chassis.
• RSP Series (75W–3000W): Built-in active Power Factor Correction (PFC > 0.95), meeting strict CE/European harmonic current compliance. Essential for precision laser systems, heavy industrial tools, and parallel multi-kilowatt arrays.
• RD Series (Dual Output): Dual isolated voltage rails (e.g. 5V and 24V or 5V and 12V), allowing simultaneous power delivery to microcontrollers/logic boards and peripheral relays without two independent PSUs.
• ERP / ERPF Series (350W–400W): Rainproof aluminum case with semi-potted silicone conformal coating, designed specifically for outdoor advertising light boxes, moving message signs, and roof displays.
