Tamura SPM Power Modules

Tamura SPM Power Modules with full-load efficiency reduce standby power requirements and are designed for applications up to 4W. The unique design of these modules significantly reduces "buzz" under light-load conditions for lower noise levels. Other advantages include miniaturization, simplification of procurement, reduction of man-hours, a wide input voltage range, and energy savings. The SPM series features 74% or higher efficiency, ±10% output voltage tolerance, 0.22A rated load current, and 15V rated output voltage. Tamura SPM Power Modules operate in a temperature range of -20°C to +95°C. Typical applications include industrial equipment, information processing equipment, AV equipment, home electric appliances, other standby power supplies, and compact power supplies.
