These 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 4kVac 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.
These 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.
