BECKHOFF KL9515 15 V DC Power Supply Terminal

Product Overview

The KL9515 (KL9515) is a precision power supply terminal designed to provide a stabilized 15 V DC output from a standard 24 V DC industrial supply. Engineered for applications requiring specific voltage regulation, such as supplying power to sensitive analog sensors or specialized measurement electronics, this terminal ensures consistent performance by maintaining an output accuracy of ±1%. Its design provides essential isolation and regulation for control systems in power generation, process automation, and manufacturing environments, effectively preventing voltage fluctuations from compromising data integrity.

Technical Configuration

The KL9515 converts a nominal 24 V DC input into a highly stabilized 15 V DC output, capable of delivering a maximum current of 0.5 A. The module features an integrated short-circuit protection mechanism and an overcurrent status LED, providing immediate diagnostic feedback if the output load exceeds safe thresholds. With a residual ripple of less than 5 mV, the terminal is optimized for noise-sensitive applications where clean power is paramount. The compact 12 mm wide housing utilizes standard spring-actuated connections, allowing it to integrate seamlessly into existing DIN rail-mounted terminal stations without requiring additional cabinet space.

Technical Specifications

FAQs

What is the primary use case for the KL9515?

The KL9515 is intended for powering field devices or sensors that specifically require a regulated 15 V DC supply rather than the standard 24 V DC available in most industrial systems.

Does the terminal include diagnostic indicators?

Yes, the terminal features an integrated overcurrent LED, which provides a visual warning if the 0.5 A output current limit is exceeded.

Is this terminal suitable for hazardous environments?

Yes, the KL9515 carries ATEX certification (II 3 G Ex nA IIC T4 Gc), allowing for operation in designated hazardous areas under specified installation conditions.

How is the output voltage stabilized?

The module uses internal regulation circuitry to maintain a precise 15 V DC output with less than 5 mV of residual ripple, ensuring clean power for connected electronics.

Installation and Operational Guidelines

• Wiring Standards: Use 0.08 to 2.5 mm squared solid or stranded wire for the input and output connections. Ensure a stripping length of 8 to 9 mm is maintained to guarantee a secure, gas-tight fit within the spring-actuated terminals.

• Heat Dissipation: Ensure the module is mounted with adequate clearance from other heat-generating components. The terminal is rated for operation up to 55 deg C; however, maintaining airflow through the DIN rail assembly will prolong the lifespan of the internal electronic components.

• Load Management: Verify that the total load connected to the 15 V DC output does not exceed 0.5 A. In cases where multiple devices are powered, calculate the cumulative current draw carefully to avoid frequent triggering of the overcurrent protection.
