Professional switched-mode 48V/240W stabilized power supply with adjustable output, short-circuit protection, and high efficiency for industrial automation and PLC applications.
The Legrand Stabilised Mono Switching Power Supply (Model 146643) is a professional-grade direct current power supply delivering stabilized 48V/5A at 240W output. This switched-mode power supply is specifically engineered for demanding PLC and automation loads that require strong inrush current capability. The unit features an adjustable output voltage range of 48V to 55V, ensuring compatibility with various system requirements. With short-circuit-proof design and high efficiency up to 94%, this power supply is ideal for industrial automation, control systems, and critical infrastructure applications.
This single-phase power supply operates at 50/60 Hz and accepts input voltages ranging from 100-240V AC (88-264V at 60Hz) or 124-370V DC. The unit is equipped with a potentiometer for front panel voltage adjustment and includes signal/relay contact feedback for active output voltage status monitoring (except 75W models). Built with aluminum casing and measuring 63mm width x 125mm height x 113mm depth, it is designed for mounting on symmetrical DIN rails with depths of 7.5mm and 15mm. The power supply conforms to international standards including UL 508, IEC EN 60950-1, and IEC EN 61204-3, with UL approval for use in USA and Canada.
The power supply features integrated PFC filter technology that minimizes harmonic pollution and provides excellent load regulation. With the ability to supply temporary overcurrents up to 150% for 3 seconds, it handles demanding startup conditions and transient loads effectively. The screw-type terminal connections accommodate wire gauges from 4-4mm², providing secure and reliable connections. Operating temperature range of -25°C to 60°C and storage temperature range of -40°C to 85°C ensure reliable performance across diverse environmental conditions.
