Main Features and Advantages
High Efficiency and Power Density: The 1606-XL480EP achieves a remarkable typical efficiency of 90%, converting AC power to usable DC with minimal loss. This high efficiency reduces the thermal load inside the control cabinet, potentially lowering cooling requirements and extending the lifespan of nearby components. The efficient design is complemented by active inrush current limiting, which prevents nuisance tripping of upstream circuit breakers and protects the internal circuitry from damage during startup.
Selectable Overload Behavior for Ultimate Flexibility: A standout feature of the 1606-XL480EP is its user-selectable overload response, configurable via a jumper on the bottom of the unit without opening the housing. In “Continuous Current” mode, the power supply provides a sustained high current during overloads, which is ideal for applications with high inrush currents, such as starting motors or charging large capacitors. This mode also simplifies parallel operation. Alternatively, the “Hiccup” mode is designed for maximum protection; during a severe overload or short circuit, the 1606-XL480EP will periodically shut down and attempt to restart, minimizing stress on the system and the power supply itself -2.
Exceptional Reliability and Long Service Life: Reliability is paramount in industrial control, and the 1606-XL480EP is built to last. It exclusively uses long-life aluminum electrolytic capacitors specified for +105°C, and only five are used in the entire design. This, combined with its high MTBF of 519,000 hours, ensures a long operational life and reduces the risk of unplanned downtime -1. Its broad operating temperature range of 0°C to +70°C, with a defined derating curve, guarantees stable performance even in harsh environments.
Parallel Operation and System Redundancy: For applications requiring higher power or critical redundancy, the 1606-XL480EP can be easily connected in parallel with up to nine other units of the same model. The output characteristic can be “softened” to ensure even current sharing among the parallel units. This capability allows for building “N+1” redundant power systems, ensuring that the control system remains operational even if one power supply fails, a crucial requirement for process-critical applications.
Advanced Power Factor Correction and Safety: The 1606-XL480EP includes active power factor correction, which improves the quality of the power drawn from the mains and reduces harmonic currents, helping to comply with EN 61000-3-2 standards -2. Additionally, it features comprehensive protection against overvoltage, overload, and short circuits. The unit also offers immunity against back-feeding loads up to 30V, protecting the power supply from external voltage sources.
Application Field
Discrete Manufacturing and Assembly Lines: The 1606-XL480EP is an ideal power source for a wide array of equipment in discrete manufacturing, including automotive assembly lines, packaging machinery, and material handling systems. It reliably powers PLCs, programmable automation controllers, and extensive networks of sensors and actuators. Its ability to deliver a stable 24V DC output, even in environments with fluctuating mains power, ensures consistent operation of critical control loops, reducing production stoppages caused by power-related issues. The continuous current overload mode is particularly beneficial for starting conveyor motors or pneumatic solenoids.
Process Industries: In continuous process industries such as oil and gas, chemical processing, and water/wastewater treatment, system availability is paramount. The 1606-XL480EP supports the creation of redundant power systems through parallel operation, guaranteeing that critical distributed control systems (DCS), Remote Terminal Units (RTUs), and safety instrumented systems receive uninterrupted power. The rugged construction and wide temperature tolerance of the 1606-XL480EP make it well-suited for outdoor or semi-outdoor installations common in these sectors, providing a reliable power backbone for essential monitoring and control instrumentation.
Infrastructure and Energy Applications: The 1606-XL480EP is also widely utilized in infrastructure projects like intelligent transportation systems, power generation, and renewable energy facilities. It provides dependable power to substation controllers, data loggers, and communication gateways in solar and wind farms. The module’s high efficiency and clean output (low ripple and noise) are critical for sensitive measurement devices and communication equipment, ensuring accurate data acquisition and reliable signal transmission. Its compliance with international standards also simplifies the certification process for global projects.
