MDNT41-0
The B & R Automation MDNT41-0 is a robust module in the MDN Midi Power Supplies series, designed to deliver a regulated 24 V DC output for industrial automation systems. Housed in durable plastic, the unit supports a direct input connection via a 5-pin screw terminal and is compatible with standard DIN rail mounting. Key features include a rated operating current of 10 A at a nominal input voltage of 24 V DC, and an integrated fuse for short-circuit and overload protection. Its primary function is to provide stable DC power to control electronics in demanding industrial environments.
Incorporating reliable components, the MDNT41-0 meets stringent durability criteria with a mechanical life of 10 million operations and an electrical life of 500,000 operations at 250 V AC switching conditions. The housing is rated IP65 for dust and water ingress protection, and the device tolerates an operating temperature range from -25 °C to +70 °C. Approvals from CE, UL, CSA ensure compliance with international safety regulations. The actuator is a plunger (spring return) type with a contact configuration of 1NO+1NC (SPDT), and screw-terminal connections facilitate reliable wiring and maintenance.
The MDNT41-0 demonstrates exceptional resilience under vibration up to 2 g (10–150 Hz) and humidity levels from 5% to 95% non-condensing. It complies with IEC 60068-2-6 vibration testing and supports installation at altitudes up to 2000 m above sea level. Surge protection and noise immunity conform to relevant IEC and EN standards, safeguarding sensitive electronics against transients. Constructed on an FR4 PCB with industrial-grade components, the front-panel fuse access and LED status indicators enable rapid diagnostics and serviceability. Overall, this power supply ensures reliable, efficient operation and enhanced system protection in industrial automation applications.
