Replacement & Compatibility FAQ
Q: Can I replace QUINT-PS/1AC/24DC/5 with QUINT4-PS/1AC/24DC/5?
A: Yes. The QUINT 4 is the direct successor with the same 45 mm footprint, identical terminal layout, and improved efficiency. It is a drop-in upgrade.
Q: Is the Siemens SITOP PSU100S 5A a direct replacement?
A: Functionally equivalent (24 V / 5 A), but the SITOP is 50 mm wide vs. 45 mm. Verify DIN rail space before substituting.
Q: Can I use a Meanwell SDR-120-24 as a replacement?
A: For non-critical loads, yes. The Meanwell lacks SFB technology and active boost, so it is not recommended for panels with multiple fused branches or high-inrush loads.
Q: What is the difference between QUINT-PS and TRIO-PS?
A: QUINT-PS includes SFB technology, active power boost, and a diagnostic relay contact. TRIO-PS is the economy series without these features — suitable for simpler applications.
Q: Does Konmask.com provide a warranty?
A: Yes. We offer a 12-month warranty on all units. Contact support@konmask.com for warranty claims.
