Product Description
MEAN WELL SPV-300-48 Switching Power Supply offers a single output of 48V DC with a power capacity of 300W. This switching power supply is designed for chassis mounting, providing reliable and efficient power conversion ideal for various industrial and laboratory applications.
The SPV-300 series allows for programmable output voltage tuning via an external control voltage ranging from 1 to 5.5 VDC, enabling output voltage adjustment from 20% to 110% to meet specific equipment requirements. This flexibility supports use in systems necessitating multiple voltage levels or fine voltage control.
Featuring an active Power Factor Correction (PFC) function with a power factor exceeding 0.95, the SPV-300-48 ensures efficient energy usage and reduced harmonic disturbances. Its fixed switching frequency at 100 kHz contributes to compact size and steady output performance.
This power supply integrates multiple protections, including short circuit, overload, over voltage, and over temperature safeguards to enhance safety and longevity. Cooling is managed by a built-in long-life DC fan equipped with speed and on/off control, maintaining optimal operating temperature and system reliability.
The unit is engineered to operate in ambient temperatures from -20°C up to 65°C, making it suitable for a wide range of industrial environments. Its compact chassis dimensions (215 mm length, 115 mm width, and 50 mm depth) facilitate installation in constrained spaces.
Applications for the SPV-300-48 include LCD panel burn-in processes, IC testing equipment, factory automation systems, and mechanical and electrical industrial uses where stable, adjustable DC power is critical.
Compliance with standards such as UL 62368-1, TUV EN 62368-1, IS 13252(Part1)/IEC 60950-1, and others ensures rigorous safety and performance benchmarks. Maximum output voltage of 48V DC with 6.25A current capacity. Built-in active PFC and high efficiency of 86.5%.
Multiple built-in protection features for safe operation. Programmable output voltage via external control voltage. Built-in variable speed DC fan for cooling. Chassis mount with compact size for easy integration. Wide operating temperature range and robust certifications.
