MC256-G003/090 by Sanyo Denki

The MC256-G003/090 is a high-performance power supply unit from Sanyo Denki, forming part of the SANUPS Power Supplies series. This compact module delivers an Output Voltage of 5V ± 2% at a Maximum Output Current of 3 A while operating from a robust Input Voltage Range of 9V to 36V. With an Efficiency of up to 95%, it minimizes dissipation and heat generation, ensuring sustained operation even under heavy loads. The unit measures just 25 mm x 15 mm x 5 mm, making it ideal for space-constrained industrial installations without sacrificing performance.

Technically, the MC256-G003/090 excels in electrical isolation and precision regulation. It provides an Isolation Voltage of up to 2500V, protecting downstream circuitry from transient surges. Voltage stability is maintained with a Line Regulation of 0.5% typical and a Load Regulation of 1% typical, ensuring consistent output under varying input or load conditions. The switching stage operates at a Switching Frequency of 500 kHz, optimizing converter size and transient response. Moreover, the Output Ripple Voltage is under 50 mV, guaranteeing clean DC output suitable for sensitive electronics. Reliability is outstanding, with a Mean Time Between Failures (MTBF) of 100,000 hours when operated within specified limits.

Operational features focus on safety and ruggedness for industrial environments. Built-in Protection Features include overcurrent and overtemperature shutdown, safeguarding both the supply and connected loads. The device functions across an Operating Temperature Range of –40°C to +85°C, and is rated for 95% humidity, making it suitable for harsh or moisture-laden atmospheres. Its metal enclosure offers mechanical durability and EMI shielding, while ventilation slots maintain adequate cooling. The design accommodates rapid thermal cycling and continuous operation, reducing downtime and maintenance requirements.

Integration is simplified through its modular profile and standardized interface. The MC256-G003/090 can be mounted directly onto DIN rails or into control panels, offering rapid deployment in industrial automation systems. Compliance with CE marking demonstrates adherence to international safety and electromagnetic compatibility standards. Typical applications span factory control cabinets, process automation equipment, robotics, and PLC power rails, where stable, precise 5V power is essential. Engineers will appreciate its small footprint, extensive protections, and high reliability for critical power distribution tasks.
