DIN Rail Power Supplies

Delivering standard 24 VDC control power from universal 90 to 264 VAC input for panel I/O, PLCs, sensors, and safety circuits, with parallel operation for capacity expansion.

Adapting proven rail-mounted platforms through modified output voltages, extended temperature range, conformal coating, custom connectorization, and screening or burn-in, reducing NRE and schedule against a ground-up design.

Engineering fully custom rail-mounted systems where envelope, rail width, multi-rail structure, or standards obligations exceed what any catalog unit meets.

Providing N+1 redundancy with decoupling and DC-UPS buffering where a single supply fault or line disturbance cannot be allowed to stop a process.

Horizon PSS takes ownership of compliance documentation and qualification testing:

Meeting EN 60204-1 requirements for protective bonding, control-circuit isolation, and correct power behavior within your emergency-stop architecture.

Supporting UL 508A industrial-control documentation and short-circuit current rating coordination your panel builder needs for North American deployment.

Passing conducted and radiated emissions and immunity testing in a drive-dense cabinet through architecture-level filtering, isolation, and grounding, addressing IEC 61000-6-2 and 61000-6-4, with CE technical-file inputs for the power subsystem.

Supporting NFPA 79 documentation where the panel serves industrial machinery.

Providing verified side-by-side derating data for sealed and densely populated cabinets, where nameplate ratings measured in open air do not survive installation.

Delivering low-noise 24 VDC and 48 VDC rails for controllers, vision systems, and instrumentation sharing a cabinet with servo and spindle drives.

Supplying hold-up and controlled-shutdown behavior that carries controllers and safety logic through line disturbances and brownouts.

Engineering conformal-coated and wide-temperature configurations for process equipment exposed to condensation, coolant mist, conductive dust, or unconditioned enclosures.

Defining specifications, compliance pathways, and schedules before commitment through transparent NRE structures covering cabinet thermal characterization, panel load profiling, and derating verification at installed ambient.

Ensuring the supply qualified in your panel matches production units identically through configuration control and PCN discipline.

Providing advance notification of changes affecting form, fit, function, or panel certifications, with qualified drop-in replacements when catalog units reach end of life.
