Physical Characteristics

The Honeywell TK-FKDXX2 measures 180 mm in width, 120 mm in height, and 85 mm in depth. This power supply weighs approximately 2.1 kilograms. The housing uses anodized aluminum alloy for effective heat dissipation. Mounting brackets attach directly to standard DIN rails.

Interface and Connectivity

Four input terminals accept line, neutral, and ground connections. Two output interfaces deliver regulated 24 VDC to downstream loads. The front panel includes three LED indicators for power status, overload warning, and fault conditions. Each terminal block accepts wire gauges from 0.5 mm² to 2.5 mm².

Internal Architecture and Energy Storage

This module integrates a primary switching converter with a flyback topology. Internal bulk capacitors store 470 µF of energy at 450 VDC. This capacitance ensures stable output during momentary input dips. A secondary-stage LC filter reduces high-frequency switching noise below 50 mV peak-to-peak.

Protection and Diagnostic Features

The Honeywell TK-FPDXX2 includes overvoltage protection set at 28 VDC. Overcurrent protection limits output current to 6.5 A with automatic recovery. Thermal sensors trigger shutdown at 85°C case temperature. Diagnostic logic generates fault signals through an opto-isolated alarm output.

Operational Environment

This power supply operates reliably between -25°C and +70°C ambient temperature. Relative humidity tolerance ranges from 5% to 95% non-condensing. The unit meets IP20 ingress protection standards for indoor panel installations. Cooling relies on natural convection without internal fans.

Application Context

Industrial automation systems benefit from this module’s robust performance characteristics. Process control panels, actuator drives, and sensor networks draw stable power from this supply. The Honeywell TK-FPDXX2 supports redundant configurations through external diode modules. Maintenance teams appreciate the quick-connect terminal design for field replacements.

Certification and Compliance

This power supply carries CE marking for European market access. UL 508 listing validates its use in industrial control equipment. The module complies with EN 61000-6-2 immunity standards. Harmonic emissions meet EN 61000-3-2 Class A requirements.
