Frequently Asked Questions
How do I install the DPF120-24S on DIN rail?
Installing the DPF120-24S on DIN rail is simple: Position: Align the supply with the TS35 DIN rail; Snap-on: Press down until the spring clip engages; Verify: Tug gently to confirm secure mounting; Wire: Connect input and output terminals. Removal: Pull down on the release tab; Lift the supply off the rail. Installation tips: Mount horizontally for best cooling; Use end stops to prevent sliding; Allow clearance for wiring (20mm minimum); Install fuse or breaker on input. The snap-on design allows tool-free installation and quick replacement. For vibration-prone environments, consider additional retention clips. Contact our FAE team for panel layout recommendations.
Snap onto TS35 rail. Press down until clip engages. Use end stops. Contact us for panel layout.
Can I use the DPF120-24S in parallel for redundancy?
Yes, the DPF120-24S supports parallel operation for redundancy: N+1 redundancy: Two units with decoupling diodes; Load sharing: Active current sharing for balanced operation; Hot-swap: Replace failed unit without system shutdown; Monitoring: Power good signals indicate unit status. Configuration: Install two DPF120-24S on DIN rail; Use redundancy module with decoupling diodes; Connect outputs in parallel through diodes; Monitor power good signals. Benefits: No single point of failure; Maintain operation during maintenance; Higher system availability. Considerations: Each unit must handle full load; Decoupling diodes cause 0.5-1V drop; Additional cost for redundancy hardware. For critical applications, redundancy is highly recommended. Contact our FAE team for redundancy configuration design.
Use two units with redundancy module for N+1. Contact us for redundancy design.
What is the power good signal on the DPF120-24S?
The DPF120-24S includes a power good (PG) signal for status monitoring: Function: Indicates when output voltage is within specification; Logic: Open collector output, active high; Threshold: Typically 90-95% of nominal output; Response: 10-50ms delay to avoid false triggers; Rating: 30V, 10mA maximum. Connection: Connect to monitoring circuit or PLC input; Use pull-up resistor to system voltage; Monitor for system status and diagnostics. Applications: System power sequencing; Fault detection and alarms; Status indication; Automated shutdown. The power good signal provides confidence that the power supply is operating correctly. For systems requiring power monitoring, this feature simplifies design. Contact our FAE team for power good interface design.
Connect to PLC or monitoring circuit. Active when output >90%. Contact us for interface design.
What wire gauge should I use for the DPF120-24S?
Recommended wire gauges for the DPF120-24S: Input wiring: 115VAC: 16 AWG (1.5mm²) minimum; 230VAC: 18 AWG (1.0mm²) minimum; Use 600V rated wire. Output wiring: 24V at 5A: 18 AWG (1.0mm²) minimum; For longer runs: 16 AWG (1.5mm²) to minimize voltage drop; Use 300V rated wire. Terminal capacity: Input terminals: 14-22 AWG (0.5-2.5mm²); Output terminals: 14-22 AWG (0.5-2.5mm²); Tightening torque: 0.5-0.6 Nm. Wiring best practices: Use ferrules on stranded wire; Keep wire lengths short; Separate input and output wiring; Use twisted pairs for noise reduction. For specific applications, calculate voltage drop based on wire length and current. Contact our FAE team for wiring recommendations.
Use 16 AWG for input, 18 AWG for output minimum. Use ferrules. Contact us for wiring design.
Can the DPF120-24S be used outdoors or in harsh environments?
The DPF120-24S is designed for industrial environments with some limitations: Operating temperature: -20°C to +70°C; Humidity: 5-95% RH non-condensing; Altitude: Up to 3000m with derating; Vibration: 5-55Hz, 19.6m/s². For outdoor or harsh environments: Enclosure: Install in IP65 or better enclosure; Temperature: Ensure ambient within operating range; Humidity: Use conformal coating or sealed enclosure; Vibration: Add damping if severe. Limitations: Not rated for direct outdoor exposure; Condensation can damage internal components; Salt air requires additional protection. For harsh environment applications: Consider Cosel's ruggedized models; Add environmental protection; Monitor operating conditions. Contact our FAE team for harsh environment design recommendations.
