Why Engineers Specify This Model
- SFB (Selective Fuse Breaking) Technology – Delivers up to 3× rated current for ≤12 ms to reliably blow downstream fuses and isolate faults without nuisance tripping of the supply itself.
- Active Power Factor Correction (PFC) – PF > 0.99 reduces harmonic distortion and lowers energy costs in large panel installations.
- Static & Dynamic Output Voltage Adjustment – Fine-tune output from 18 to 29.5 VDC via front-panel potentiometer to compensate for long cable runs.
- Integrated Monitoring & Signaling – Floating relay contact (DC OK) and LED status indicator enable remote SCADA/PLC fault detection without additional modules.
- Parallel Redundancy Ready – Supports N+1 redundancy configurations with optional QUINT-DIODE decoupling modules for mission-critical uptime.
- Wide Temperature Range – Full rated output from -25 °C to +70 °C; no derating required up to 60 °C.

Application-Specific FAQ
Q: Can this PSU power a Siemens S7-1500 PLC with multiple I/O modules?
A: Yes. The 20 A output comfortably powers a typical S7-1516 CPU with up to 16 digital I/O modules. Use the PHOENIX CONTACT STEP PS tool to verify your exact load budget.
Q: Is the QUINT-PS-100-240AC/24DC/20 suitable for 110 VAC North American installations?
A: Yes. The wide-range input (85–264 VAC) accepts both 110 VAC (60 Hz) and 230 VAC (50 Hz) without any switch or jumper change.
Q: How does SFB differ from a standard current-limiting PSU?
A: Standard PSUs fold back current under fault, which can prevent fuses from blowing. SFB actively pushes 3× rated current for up to 12 ms, guaranteeing fuse operation and faster fault isolation.
Q: Can two units be paralleled for 40 A output?
A: Direct paralleling is not recommended. Use the QUINT-DIODE/40 redundancy module to safely combine two units in an N+1 configuration.
Q: What is the warranty?
A: Konmask.com provides a 12-month warranty against defects in materials and workmanship. PHOENIX CONTACT OEM warranty terms apply to new, sealed units.
