        More Information

        Overview Manuals Line Connection Thermal Loading Fault Characteristic Parallel Output

        Features:

        • A selector separates the 120 V and 230 V class input windows.
        • The isolated 24 V output is adjustable and follows a U-I overload characteristic.
        • Two identical supplies may be paralleled within the documented current limits.
        Siemens 6EP1334-1LB00 routes single-phase power through L1, N and PE before producing the isolated DC control supply.

        Rated current remains 10 A through +45 °C and changes to 7 A at the +60 °C operating boundary.

        The paired output screws simplify conductor landing but do not divide the secondary into independently regulated channels.

        The Siemens 6EP1334-1LB00 SITOP PSU100L 24 V DC 10 A Stabilized Power Supply may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

        Selector and Input Wiring

        • Source terminals: Single-phase supply enters through L1 and N, with PE connected to the protective conductor.
        • Lower window: The 120 V class setting covers 93 to 132 V AC.
        • Upper window: The 230 V class setting covers 187 to 264 V AC.
        • Feeder protection: The documented line feeder uses a characteristic-C miniature circuit breaker rated from 10 A.

        Current Rating Across Temperature

        • Rated region: The full 10 A output is available from 0 through +45 °C.
        • Warm boundary: At +60 °C the permitted output current is 7 A.
        • Cooling path: Natural convection carries heat away from the rail-mounted housing.
        • Conductor sizing: Output cables must be selected for the maximum rms current used in the installation.

        Overload and Short-Circuit Response

        • Voltage regulation: The selected DC voltage is maintained until the load reaches the U-I boundary.
        • U-I response: Beyond the boundary, output voltage and current follow the documented U-I curve.
        • Short circuit: The output remains protected with a typical continuous short-circuit current of 12.6 A.
        • Voltage ceiling: Secondary overvoltage protection keeps the output below 33 V.

        Shared-Bus Conditions

        • Maximum quantity: Power expansion permits no more than two matching supplies.
        • Common voltage: Both potentiometers must be aligned before the outputs are joined.
        • Terminal use: The duplicated positive and negative screws give each conductor a landing point on the common bus.
        • Load check: The combined arrangement still follows the specified thermal current limits for each supply.
        Description
        A selectable 120/230 V input places Siemens 6EP1334-1LB00 on a single-phase AC supply, where terminals L1, N and PE feed the PSU100L conversion stage. The selector separates the 93–132 V and 187–264 V operating windows, and the input stage provides at least 20 ms of power-failure buffering at rated load.

        On the secondary side, 6EP1334-1LB00 produces an isolated 24 V DC output that can be adjusted from 22.8 to 28 V. The 10 A, 240 W rating is available through +45 °C, while the documented load boundary falls to 7 A at +60 °C; two positive and two negative screws provide parallel landing points for the same output circuit.

        Overload handling on 6EP1334-1LB00 follows a U-I characteristic rather than the automatic restart behavior assigned to the smaller PSU100L models. The supply is short-circuit proof, its typical continuous short-circuit current is 12.6 A, and secondary overvoltage protection holds the output below 33 V.

        The enclosure of 6EP1334-1LB00 snaps onto a TH35 mounting rail and operates by natural convection from 0 to +60 °C. Up to two matching units may be connected in parallel, but their adjusted voltages and conductor sizing must be checked against the shared load before the outputs are combined.

        Technical notes
        The input selector on Siemens 6EP1334-1LB00 must match the connected 120 V or 230 V class before energization; the two positive and two negative terminals are duplicated points on one output.

        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
        What should be checked if 6EP1334-1LB00 does not start after a mains change?
        Confirm that the input selector on 6EP1334-1LB00 matches the connected 120 V or 230 V class and that the source remains inside the corresponding voltage window.
        Can 6EP1334-1LB00 provide the full 10 A at +60 °C?
        No. 6EP1334-1LB00 is rated for 10 A through +45 °C and 7 A at +60 °C, so the load must be reduced at the upper operating temperature.
        Does 6EP1334-1LB00 repeatedly restart during a sustained overload?
        6EP1334-1LB00 uses a U-I characteristic; the automatic shutdown-and-restart behavior documented for smaller PSU100L variants must not be assigned to this 10 A model.
        Are both positive screws required when wiring 6EP1334-1LB00?
        The two positive screws and two negative screws on 6EP1334-1LB00 are parallel landing points on one output, so use them according to conductor sizing and distribution needs.
        What is the continuous short-circuit value for 6EP1334-1LB00?
        The typical continuous short-circuit current of 6EP1334-1LB00 is 12.6 A, with the output protected by its U-I characteristic.
        How should two 6EP1334-1LB00 units be prepared for parallel operation?
        Before joining two 6EP1334-1LB00 outputs, match their adjusted voltages, confirm identical operating conditions and size the shared conductors for the combined load.
