Selection Guide
Use the following criteria to confirm the SFL24-24-100RED is the right choice — or to identify the best alternative:
- Output voltage – Confirm your system bus is 24 VDC. If 12 VDC or 48 VDC is required, select a different Sola series.
- Load current – Sum all 24 VDC loads. The SFL24-24-100RED provides 4.2 A continuous. Add 20–30% headroom; upgrade to a 5 A or 10 A unit if needed.
- Input voltage range – Universal 85–264 VAC input covers single-phase 110 V and 220 V systems worldwide.
- Mounting space – Verify DIN rail width and depth clearance in your enclosure.
- Certifications – UL 508 is required for North American industrial panels; CE for European installations.
- Redundancy – For critical applications, pair two units with a Sola redundancy module for N+1 operation.

Replacement & Compatibility FAQ
Q: Is the Meanwell DR-100-24 a direct drop-in replacement for the SFL24-24-100RED?
A: Electrically compatible (24 VDC / 4.5 A), but the DR-100-24 uses a different housing form factor and lacks UL 508 listing. Suitable for non-UL-panel applications.
Q: Can I use the SFL24-24-100RED to power a Siemens S7-1200 PLC?
A: Yes. The S7-1200 CPU and standard I/O modules operate on 24 VDC. Verify total current draw of CPU + I/O does not exceed 4.2 A.
Q: What does the “RED” suffix mean in SFL24-24-100RED?
A: It denotes the red housing color variant, used for visual identification in multi-PSU panels. Electrically identical to standard SFL24-24-100 units.
Q: Is the SFL24-24-100RED still in production?
A: Contact Konmask.com for current availability. We maintain stock of both new and refurbished units and can source compatible alternatives if the original is discontinued.
Q: Do you provide a warranty?
