Key Product Advantages
-
Space-Saving Design: Its slim profile allows for maximum utilization of space within control cabinets.
-
High Reliability (MTBF): Built with industrial-grade components to ensure a long service life and high Mean Time Between Failures.
-
Power Reserve: Many XL models include a “Power Boost” feature, allowing the unit to handle short-term overloads without voltage drops.
-
Low Electromagnetic Interference (EMI): Meets stringent industrial standards for low noise emission and high immunity.
-
Easy Integration: Features pluggable terminals (on some versions) and a simple DIN-rail clip for fast installation.
Important Considerations & Precautions
-
Cooling & Ventilation: Ensure at least 40mm of clearance above and below the device, and 15mm on the sides to allow for natural convection cooling.
-
Derating: Be aware that the output power capacity decreases when operating in ambient temperatures exceeding $60^{\circ}C$.
-
Input Protection: While the unit has internal fuses, it is recommended to use an external circuit breaker or fuse on the input side for added safety.
-
Polarity: Double-check the DC output polarity before powering on to prevent damage to connected sensitive electronic loads.
Product Applications
The 1606-XL120DR is versatile and used across various sectors:
-
Industrial Control Systems: Powering PLCs (Programmable Logic Controllers), HMI panels, and I/O modules.
-
Machine Building: Providing stable 24V DC power for sensors, actuators, and small DC motors.
-
Process Automation: Used in oil & gas, water treatment, and chemical plants where reliability is critical.
-
Redundant Systems: Often used in pairs with a redundancy module to ensure 24/7 uptime for critical infrastructure.
