        Overview Manuals Power Assembly Redundancy Rack Integration Voltage Options

        Features:

        • Three guided positions for PS1000 power-supply modules
        • Standard 19-inch cabinet format
        • Supports capacity expansion or redundant supply arrangements
        M3421 groups as many as three PS1000 converters in one serviceable mechanical assembly rather than scattering individual supplies through the cabinet.

        The number of populated positions is selected from the actual load and reserve requirement; spare capacity is not inferred merely from an empty slot.

        Ventilation, protective devices, and isolation procedures are planned for the whole assembly because removing one converter can change the capacity available to the connected safety system.

        HIMA M3421 19-inch PS1000 power-supply subrack is supported by Apter Power for availability and quotation requests; product references can be supplied to compare the installed PS1000 arrangement.

        M3421 power-module arrangement

        • Three positions: Accepts a maximum of three PS1000 converter modules
        • Guided insertion: Each supply occupies a defined mechanical location in the subrack
        • Selective population: Only the positions needed by the capacity and reserve calculation are fitted
        • Service boundary: One converter can be identified and isolated without replacing the empty carrier

        M3421 capacity and redundancy

        • Normal demand: Installed PS1000 capacity must cover the continuous downstream load
        • Reserve case: The remaining supplies are checked against load after the planned single fault
        • Wiring scheme: Redundancy depends on the actual input and output connections, not the shelf alone
        • Protection: Fuses or other branch protection are coordinated with each installed converter

        M3421 cabinet integration

        • Rack width: Fits the 19-inch cabinet format used by the supported power assembly
        • Airflow: Clearance is maintained around every populated supply position
        • Cable access: Input and distribution wiring remain reachable for inspection and isolation
        • Maintenance plan: Before module exchange, technicians confirm which loads remain energized

        M3421 supply-unit variants

        • 24 V outputs: The PS1000 range includes supply cassettes for 24 V DC control-system distribution.
        • 48 V outputs: Additional PS1000 versions extend the carrier arrangement to 48 V DC applications.
        • Input choices: The PS1000 family includes versions for 115 V AC and 230 V AC mains input.
        • Common carrier: The PS1000 power-supply units are installed in the M3421 subrack.
        Description
        Built as a 19-inch carrier for the PS1000 power family, HIMA M3421 is a subrack that accommodates as many as three supply modules in one cabinet assembly.

        The guided positions in M3421 keep the converters mechanically aligned and provide a consistent arrangement for input, output, and service access. A project may populate one, two, or three positions according to the required capacity and reserve concept.

        Using several PS1000 units makes scalable or redundant supply layouts possible, but the subrack itself does not determine the final load-sharing method. Downstream demand, converter ratings, protective devices, and the approved redundancy scheme are calculated for the complete power system.

        Cabinet planning around M3421 must preserve ventilation and working clearance for all installed converters. Before a module is removed, its assigned branch and the effect on remaining power capacity are identified.

        Technical notes
        M3421 provides three PS1000 positions; actual capacity and redundancy depend on the installed supply modules, downstream load, protective devices, and the approved wiring design.

        FAQS

        The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
        VIEW ALL FAQS
        How many PS1000 modules fit in M3421?
        M3421 provides positions for up to three PS1000 power-supply modules.
        Does installing three supplies automatically make M3421 redundant?
        With M3421, no. Redundancy depends on the selected converters, load-sharing arrangement, wiring, protection, and available reserve after one supply is lost.
        Can M3421 be operated with an empty converter position?
        On M3421, the modular subrack can be populated according to project demand, provided the remaining configuration follows the approved power design.
        What should be checked before removing a PS1000 unit from M3421?
        For M3421, identify the module input and output branches, confirm the load carried by the remaining supplies, and follow the system isolation procedure.
        Why is ventilation important around a fully populated M3421?
        With M3421, three converters can create significant heat; cabinet airflow and clearance must remove that heat without obstructing module service.
        Can a different 19-inch power shelf replace M3421?
        A visually similar shelf is not sufficient. The mechanical guides, PS1000 interface, wiring arrangement, and system approval must match M3421.
        What information is needed to size an M3421 power assembly?
        For M3421, collect the PS1000 module ratings, normal and fault-case loads, required reserve, input sources, protective devices, and cabinet cooling conditions.
