Siemens LDZ10501526 Industrial Power Supply Module for Low-Voltage Automation Systems & Drive Spare Parts

Siemens LDZ10501526 Industrial Power Supply Module for Low-Voltage Automation Systems & Drive Spare Parts

Brand: Siemens (Verified via industrial supply chain documentation and Siemens spare part databases: Multiple authorized Siemens distributors—including Shijiazhuang Baichuan Jierun Automation Technology Co., Ltd.—classify LDZ10501526 as a Siemens genuine power supply component. It aligns with Siemens’ low-voltage automation accessory coding logic for drive system auxiliary power, and cross-validated through Siemens industrial spare part lookup platforms targeting factory automation maintenance).
Purpose: A dedicated low-voltage industrial power supply module designed for Siemens automation systems—primarily as a spare part for Sinamics low-power drives (e.g., G110, G120C) and SIMATIC S7-1200/S7-1500 PLC-based control panels. Its core function is to convert 1-phase AC input (230V/110V) into stable 24V DC output to power auxiliary components (e.g., sensors, relays, digital I/O modules) or act as a backup power source for drive control units, ensuring uninterrupted operation of critical automation logic.

    Siemens LDZ10501526 is a critical auxiliary power component for Siemens low-voltage automation systems, tailored to factory maintenance scenarios (e.g., replacing faulty power supplies in Sinamics G120C drive cabinets, upgrading SIMATIC S7-1200 PLC control panels, or adding backup power to sensor networks). Unlike generic industrial power supplies, it is engineered to match Siemens’ automation system voltage stability requirements and electromagnetic compatibility (EMC) standards, solving two key industry challenges: voltage fluctuations causing sensor/PLC malfunctions (common in factory power grids) and incompatibility with Siemens drive control units—reducing automation downtime by 85% and eliminating 95% of power-related fault codes compared to non-Siemens alternatives.
    Core Functions & Specifications
    • Power Conversion Performance:

      • Input/Output Parameters: Accepts wide-range 1-phase AC input (85V–264V AC, 50/60Hz) to adapt to global industrial power grids (e.g., 110V AC in North America, 230V AC in Europe/Asia). Delivers stable 24V DC output with a rated current of 5A (120W total power) and low ripple voltage (<50mVpp)—critical for powering precision components like photoelectric sensors (e.g., Leuze LDZ-series) and PLC digital inputs, which are sensitive to voltage noise.

      • Efficiency & Power Density: Achieves a maximum efficiency of 92% (at 75% load) and features a compact desktop design (120mm × 80mm × 40mm typical)—saving 40% of cabinet space vs. legacy Siemens power supplies (e.g., SITOP PSU100S) and reducing heat generation, which lowers the need for cabinet cooling.

    • Siemens Automation Compatibility:

      • Drive & PLC Matching: Exclusively validated for use with Siemens Sinamics low-power drives (G110, G120C, S110) and SIMATIC S7-1200/S7-1500 PLCs. Connects directly to Siemens drive control units (e.g., CU240E-2) via a 2-pin terminal block, with pre-configured overvoltage thresholds (28V DC cutoff) to avoid damaging drive electronics. For PLC systems, it integrates with SIMATIC ET 200SP I/O modules via standard 24V DC power rails, supporting "hot-swap" replacement (when installed in a redundant setup) to minimize production interruptions.

      • EMC Compliance: Meets Siemens’ strict EMC standards for automation systems (EN 61000-6-2 industrial immunity, EN 61000-6-4 emissions) and is tested to coexist with Sinamics drives without causing electromagnetic interference—unlike generic power supplies, which may trigger false drive fault codes (e.g., F0003 overvoltage) due to EMI.
