SD834 3BSC610067R1 Power Module (Industrial-Grade High-Current DC Power Supply for Heavy-Duty Automation Systems)
The SD834 3BSC610067R1 is an industrial-grade high-performance power module engineered to deliver stable, high-current DC power for heavy-duty industrial automation systems—including large-scale PLC/DCS controllers, high-power actuators, and multi-module control cabinets. It features a rated output voltage of 24V DC and a rated output current of 20A, with ultra-high load regulation (≤±0.3%) and ultra-low ripple noise (≤25mVp-p) to protect sensitive and high-power components from voltage fluctuations. Compliant with international industrial safety and efficiency standards (IEC 61558, EN 60950, 80 Plus Bronze), it adapts to harsh industrial environments (e.g., high dust, vibration) and is widely used in heavy manufacturing, process control, and energy sector control systems.
This module adopts a rugged, heat-dissipating aluminum alloy housing with an optimized internal heat sink structure, enabling long-term full-load operation without overheating (temperature rise ≤40℃ at full load). It integrates a 5-layer protection system: overload, overvoltage, short-circuit, overtemperature, and reverse polarity protection—effectively preventing damage to the module and connected equipment from abnormal power conditions. It supports an ultra-wide AC input range of 85-264V (50/60Hz), ensuring compatibility with global power grids (110V, 220V, 240V). The operating temperature range of -30℃~+75℃ allows stable performance in extreme cold (e.g., outdoor control cabinets in low-temperature regions) and high-temperature (e.g., metallurgical workshops) environments. It supports 35mm standard DIN rail mounting for space-efficient installation in control cabinets, and is equipped with triple LED indicators (input power, output status, fault alarm) for real-time monitoring and rapid fault diagnosis.
① High-Current Stability: 20A rated output + 25A peak current, supporting heavy-duty automation components; ② Ultra-Precise Output: ≤±0.3% load regulation + ≤25mVp-p ripple, protecting sensitive high-power devices; ③ Comprehensive Protection: 5-layer protection system eliminates risks from power anomalies; ④ Extreme Environment Adaptation: -30℃~+75℃ operating range + wide input voltage, suitable for global harsh sites; ⑤ Energy-Efficient: ≥89% full-load efficiency (80 Plus Bronze), reducing long-term energy consumption.
① Heavy Manufacturing: Power supply for large-scale production line control cabinets, high-power conveyor motors, and welding robot controllers; ② Process Industry: Power support for metallurgical blast furnace control systems, chemical reactor control modules, and oil refinery instrumentation; ③ Energy Sector: Power for wind turbine control systems, photovoltaic inverter clusters, and power substation automation equipment; ④ Infrastructure: Power supply for large-scale water treatment plant control cabinets and smart grid distribution automation systems; ⑤ Transportation: Power for rail transit signal control cabinets and port crane automation controllers.
① Confirm the input voltage matches the 85-264V AC range before installation—do not connect to DC input to avoid module burnout; ② Do not exceed the rated output current (20A) for long-term use; peak current (25A) should not last more than 10 seconds to prevent overtemperature shutdown; ③ Install in a well-ventilated control cabinet (minimum 50mm clearance on both sides) to ensure heat dissipation—avoid stacking with other high-heat components (e.g., frequency converters); ④ Disconnect input power before wiring, and ensure correct polarity (positive/negative) to prevent reverse polarity damage; ⑤ Regularly inspect terminal connections (torque: 2.5N·m for power terminals) to avoid loose contacts causing abnormal heating or voltage drop; ⑥ Clean the heat sink surface quarterly (in dusty environments) to remove dust accumulation and maintain heat dissipation efficiency
