Tamura RPM Power Modules

Tamura RPM Power Modules with full-load efficiency reduce standby power requirements and are ideally suited for applications up to 80W. This energy-saving series offers a rated output voltage of 12V, 24V, 36V, or 48V, along with 87% or higher efficiency and typical standby power as low as 50mW. The unique design of the RPM modules significantly reduces “buzz” under light-load conditions for lower noise levels. Additional features include miniaturization, simplification of procurement, reduction of man-hours, and a wide input voltage range. Tamura RPM Power Modules operate in a temperature range of -20°C to +80°C. Applications include industrial equipment, information processing equipment, audio-visual (AV) equipment, home electric appliances, and other standby power supplies.

Built-in protective functions (overcurrent, overvoltage, and overheat protection)
Unique design ensures significant reduction in “buzz” under light-load conditions for lower noise level
Easy to design compact AC/DC with external components

Applications

Industrial equipment
Information processing equipment
AV equipment

Home electric appliances
Other standby power supplies and compact power supplies
