The Traco Power TPP 40 Series, specifically the TPP 40-321M2 model, is an enclosed AC/DC power supply rated at 40 Watts. It provides three distinct output voltages: +12VDC at 3.34A, +5VDC at 6A, and -12VDC at 0.5A. The unit operates with a universal input voltage range of 85-264 VAC or 120-370 VDC and boasts a typical efficiency of 88%.
Designed for demanding applications, this power supply meets stringent medical safety standards, including IEC/EN/ES 60601-1 edition 3.2 for 2 x MOPP, and features low leakage current (<75 µA) suitable for BF applications. It also complies with EMC standards IEC 60601-1-2 ed.4.
The TPP 40-321M2 is built for reliability with industrial-grade components and excellent thermal management. It operates across a wide temperature range of -40°C to +70°C at full load, extending to 85°C with 50% load derating. Its compact dimensions (102.4mm x 60.5mm x 34.5mm) and chassis mount type make it suitable for space-critical designs. The power supply is prepared for protection class I and II and meets ErP directive requirements for low no-load power consumption.
The TPP 40-321M2 provides three output voltages: +12 VDC, +5 VDC, and -12 VDC.
The maximum output currents are 3.34 A for +12 VDC, 6000 mA for +5 VDC, and 500 mA for -12 VDC.
The typical efficiency of the TPP 40-321M2 is 88%.
The operating temperature range is -40°C to +70°C at full load, and up to 85°C with 50% load derating.
The dimensions of the TPP 40-321M2 are 102.4mm in length, 60.5mm in width, and 34.5mm in height.
The TPP 40-321M2 is approved by CB, CE, and cURus agencies.
The leakage current is less than 75 µA, making it suitable for BF applications.
