Open frame power supplies, also known as chassis-mount or U-frame power supplies, are unenclosed AC-DC or DC-DC converters designed for integration into larger systems. These units typically feature a metal chassis or open PCB construction, allowing for efficient heat dissipation and flexible mounting within control cabinets, industrial enclosures, or custom equipment. Key technical parameters include input voltage ranges (e.g., 85-264 VAC or 120-370 VDC), output voltages from 3.3V to 48V DC, power ratings from 10W to several kilowatts, and efficiency levels often exceeding 85%. They may include features like active PFC, overvoltage protection, short-circuit protection, and remote on/off control. Common form factors include single-output, dual-output, and triple-output configurations, with connection via screw terminals, Molex connectors, or PCB pins.
Open frame power supplies are predominantly used in industrial automation, telecommunications, medical equipment, LED lighting, and test and measurement systems. They are ideal for applications requiring reliable, cost-effective power conversion where space is at a premium and the power supply is mounted inside a host device or cabinet. Typical environments include factory floors, server rooms, broadcast studios, and laboratory benches. Their open design facilitates forced-air or convection cooling, making them suitable for continuous operation in demanding conditions.
Within our catalog, subcategories include single-output open frame supplies (e.g., model series like MW10-12S12, where MW10 indicates the series, 12S denotes single output, and 12 is the output voltage), dual-output models (e.g., MW10-12D12), and triple-output units (e.g., MW10-12T12). Other relevant series include the MW20, MW30, and MW50 families, each offering different power levels and output configurations. The article code structure typically follows a pattern: [Series][Output Count][Output Voltage], e.g., MW10-12S12 for a 12V single-output supply. We also stock universal input models with active PFC for global compliance.
