Medical AC-DC external power supplies deliver up to 65-W and 110-W
Offered with a choice of output voltages from 12 to 48 Vdc, the DTM-C series operates from a universal AC input of 90 to 264 Vac (47-63 Hz). With average efficiency greater than 87% and offload power consumption of less than 0.5 W, all models in the DTM-C series comply with ErP (Energy Related Products), EISA (Energy Independence and Security Act of 2007), CEC (Californian Energy Commission) and Global Efficiency Level V regulations.
The external power supplies are packaged in low profile, insulated enclosures and are convection cooled. The operating temperature range is from 0 up to 50°C (DTM65-C) and 0 to 40°C (DTM110-C) at full load without derating. With 4 kVac input to output isolation, all models in the DTM-C series comply with UL/EN/IEC60601-1 Editions 2 & 3 safety approvals for medical equipment.
The highly efficient external adapters include over voltage and short circuit protection circuitry. In addition, the DTM65-C meets the EN55011 and EN60601-1-2 Class B conducted and radiated EMI standards; DTM110-C meets EN55022 and FCC Part 18 Class B conducted and radiated EMI standards and harmonic correction to EN61000-3-2. All models in the DTM-C range meet EN55024 for immunity and Safety Class I (Altitude 2000m), are CE marked and can withstand 20G shock.
