        Overview Manuals Input Selection Output Adjustment Overload Response Rail Integration

        Features:

        • Wide-range AC and DC inputs feed one stabilized secondary output.
        • The 12 V DC output can be adjusted from 10.5 to 16.1 V.
        • Current limiting, short-circuit protection and an output-OK LED are built in.
        Siemens 6EP1322-1SH03 occupies a 72 mm DIN-rail width and supplies up to 4.5 A for the connected 12 V control circuit.

        Two positive and two negative screw terminals provide duplicated landing points on the same regulated output potential.

        Natural convection governs enclosure placement, with full rated output available through +55 °C before derating begins.

        The Siemens 6EP1322-1SH03 LOGO!Power 12 V DC 4.5 A Stabilized Power Supply may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

        AC and DC Source Path

        • AC entry: A single-phase source connects within the documented 85 to 264 V AC range.
        • DC entry: The same input section accepts 110 to 300 V DC when a DC source is used.
        • Frequency boundary: AC operation remains within the 47 to 63 Hz line-frequency window.
        • Buffer interval: At 187 V input, stored energy maintains rated output for at least 40 ms during a line interruption.

        Voltage Setting and Terminal Relationship

        • Rated point: The nominal secondary condition is 12 V DC at 4.5 A.
        • Adjustment control: The front potentiometer moves the regulated value between 10.5 and 16.1 V.
        • Terminal pairing: Two positive screws share one output potential and two negative screws share the return.
        • Local indication: The green LED confirms that the regulated output remains present.

        Current Boundary Behavior

        • Normal region: The supply holds the selected voltage until load demand reaches the current limit.
        • Limiting point: Output current is limited at 5.8 A rather than increasing without control.
        • Short circuit: The secondary remains protected with no more than 7 A continuous short-circuit current.
        • Parallel limit: Only two identical units are permitted in a parallel power arrangement.

        Mounting and Cooling Boundary

        • Carrier: The enclosure snaps onto a TH35 mounting rail to EN 60715.
        • Cooling method: Heat is removed by natural convection without a fan.
        • Rated-temperature point: Full output is available through +55 °C.
        • Upper range: Operation may continue to +70 °C when the documented derating is applied.
        Description
        The compact Siemens 6EP1322-1SH03 belongs to the LOGO!Power family and converts a single-phase AC or DC source into a stabilized 12 V DC supply. Its input stage accepts 85 to 264 V AC or 110 to 300 V DC, allowing the same unit to operate from either documented source type without changing the output function.

        A front potentiometer sets the output of 6EP1322-1SH03 between 10.5 and 16.1 V. The regulated output is rated at 4.5 A and 50 W, while two positive and two negative screw terminals divide the outgoing conductors without altering their common electrical potential.

        When loading reaches the current boundary, 6EP1322-1SH03 limits output current at 5.8 A and remains short-circuit proof with a continuous short-circuit value of no more than 7 A. The green output-OK indicator follows the secondary voltage, and a minimum 40 ms buffering interval at 187 V carries the output through a brief input interruption.

        For enclosure integration, 6EP1322-1SH03 snaps onto a TH35 rail and relies on natural convection. It can deliver rated output through +55 °C before temperature derating applies, with operation extending from -20 to +70 °C; no more than two identical units may be connected in parallel when additional output capacity is required.

        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
        Can 6EP1322-1SH03 be powered from a DC control bus instead of AC mains?
        Yes. 6EP1322-1SH03 accepts 110 to 300 V DC as well as 85 to 264 V AC, provided the input connection follows the documented polarity and protection requirements.
        Why does the output of 6EP1322-1SH03 measure above 12 V after installation?
        The output potentiometer on 6EP1322-1SH03 permits adjustment from 10.5 to 16.1 V, so verify its setting before treating a value above 12 V as a fault.
        Do the two positive terminals on 6EP1322-1SH03 provide separate isolated channels?
        No. Both positive terminals on 6EP1322-1SH03 share the same regulated output potential, and the two negative terminals share the common return.
        What happens when a connected load exceeds the rating of 6EP1322-1SH03?
        6EP1322-1SH03 enters current limiting at 5.8 A and is short-circuit proof, with continuous short-circuit current limited to a maximum of 7 A.
        At what cabinet temperature must 6EP1322-1SH03 be derated?
        The rated output of 6EP1322-1SH03 is available through +55 °C; above that point, apply the documented derating up to the +70 °C operating limit.
        How many 6EP1322-1SH03 units may be connected in parallel?
        Siemens permits a maximum of two 6EP1322-1SH03 supplies in the documented parallel arrangement; verify matched voltage settings before joining their outputs.
