Selection Guide
Use the following criteria to confirm the QUINT-PS/1AC/24DC/10 is the right choice — or to identify a suitable alternative:
- Step 1 — Load Calculation: Sum all 24 VDC loads in your panel. Add 20–30% safety margin. If total ≤ 240 W, this model is sufficient.
- Step 2 — Input Voltage: Confirm your supply is 100–240 VAC single-phase. For 3-phase input, consider QUINT-PS/3AC/24DC/10.
- Step 3 — Fuse Tripping Requirement: If downstream fuses must trip reliably under short-circuit, SFB boost is essential — choose original or QUINT4 upgrade.
- Step 4 — Environment: For ATEX Zone 2 or marine (DNV) applications, original certification is required — generic equivalents may not qualify.
- Step 5 — Budget vs. Features: For cost-sensitive projects without diagnostics needs, consider PULS QS10.241 or Omron S8VK-G24024 as alternatives.

Replacement & Compatibility FAQ
Q: Can I replace QUINT-PS/1AC/24DC/10 with QUINT4-PS/1AC/24DC/10?
A: Yes. The QUINT4 (2904602) is the direct next-generation replacement with identical mounting and improved efficiency. It is the recommended upgrade path.
Q: Is the Siemens SITOP 6EP1334-2BA20 a drop-in replacement?
A: Electrically compatible (24V/10A, DIN rail), but the relay signal output pinout and diagnostic features differ. Verify your monitoring circuit before substitution.
Q: Can this PSU power a Siemens S7-1500 PLC system?
A: Yes. The S7-1500 CPU and I/O modules operate on 24 VDC. Ensure total load including I/O does not exceed 10 A.
Q: What is the difference between QUINT-PS and QUINT-PS/M?
A: The /M variant adds a manual current-limiting mode for commissioning. The standard QUINT-PS/1AC/24DC/10 uses automatic SFB boost only.
Q: Do you provide a warranty?
A: Yes — 12-month warranty on new units, 6-month on refurbished. Contact us for details.
