Input and Supply Specifications

The Pepperl+Fuchs KFA6-STR-1.24.500 offers remarkable flexibility on the input side. You can connect the supply voltage to terminals 14 and 15. The rated input voltage range spans from 90 to 253 V AC, accommodating both 115 V AC and 230 V AC systems with a frequency of 48 to 63 Hz. For protection, you need to install a back-up fuse. Depending on your setup, you can use a B characteristic fuse rated at 16 A, 10 A, or 6 A. Notably, the device only dissipates 2.5 W of power, making it an energy-efficient choice for your cabinet.

Output and Performance Characteristics

On the output side, the KFA6-STR-1.24.500 delivers a nominal voltage of 24 V DC. The output rated operating current reaches a maximum of 500 mA. Specifically, the unit can sustain this 500 mA output even at elevated ambient temperatures up to 60 °C (140 °F), ensuring reliable performance in harsh conditions. Furthermore, the output features permanent electronic short-circuit protection. This protection mechanism safeguards both the power supply itself and any connected downstream devices from damage due to overcurrent events.

Connection Flexibility and Installation

This Pepperl+Fuchs power supply provides you with two convenient connection methods. You can either connect your load directly to the screw terminals 7+ and 8- or utilize the integrated Power Rail connection. This dual option makes the KFA6-STR-1.24.500 suitable as both a standalone power supply and a dedicated Power Rail supply for the entire system. The unit features removable screw terminals, which significantly simplifies wiring and maintenance tasks. Additionally, the housing type B2 measures 20 x 119 x 115 mm (0.8 x 4.7 x 4.5 inch) and supports mounting on a 35 mm DIN mounting rail per EN 60715:2001.

Safety and Regulatory Compliance

The KFA6-STR-1.24.500 complies with stringent safety standards. The galvanic isolation between the power supply input and output provides safe isolation according to DIN VDE 0106, with a rated insulation voltage of 253 Veff. Additionally, the device meets the requirements of the EMC Directive 2014/30/EU, successfully passing tests per EN 55022, EN 61000-4-2, EN 61000-4-3, EN 61000-4-4, EN 61000-4-5, EN 61000-4-6, EN 61000-4-11, EN 61000-6-2, and EN 61000-6-3. It also complies with the Low Voltage Directive 2014/35/EU per EN 60950-1 and insulation coordination per EN 50178. An LED indicator on the front panel provides clear visual status feedback, while a labeling space allows for easy circuit identification.
