Application-Specific FAQ
Q: Can this PSU power a 48 V PoE switch directly?
A: Yes. The QUINT-PS/1AC/48DC/10 output is compatible with IEEE 802.3bt (PoE++) switches rated for 48–57 VDC input. Verify the switch’s maximum input voltage before connecting.
Q: Is the output voltage adjustable for 56 V telecom applications?
A: Yes. The output is adjustable from 45 V to 56 V via the front-panel potentiometer, making it suitable for ETSI 300 132-2 compliant telecom installations.
Q: Can two units be paralleled for redundancy?
A: Direct paralleling is not recommended without a QUINT-ORING module. The QUINT-ORING/24DC/2X10/1X20 (re-rated for 48 V) provides true diode-ORing with active MOSFET switching for lossless redundancy.
Q: What is the derating at elevated ambient temperatures?
A: Full 10 A output is available up to +60 °C. Above +60 °C, derate linearly to 6 A at +70 °C. Ensure adequate convection airflow (minimum 50 mm clearance above and below).
Q: Does this unit support remote on/off control?
A: The standard QUINT-PS/1AC/48DC/10 does not include a remote inhibit input. For remote control functionality, consider the QUINT4-PS series with integrated remote on/off.
Q: What is the warranty?
A: Phoenix Contact provides a 3-year manufacturer warranty. Konmask.com additionally offers a 12-month return-to-base warranty on all units sold through our platform.
