Power Adapters Offer Class I and Class II Insulation
Including a 4-pin power DIN plug, Tumbler Technologies + TRUMPower’s TMP150 Series medical-grade AC/DC desktop power adapters exhibit Class I and Class II insulation., Tumbler Technologies + TRUMPower’s TMP150 Series medical-grade AC/DC desktop power adapters exhibit Class I and Class II insulation. The Class I units present an IEC 320/C14 AC inlet with a ground pin, and earth leakage current of 90 µA at 115 VAC or 150 µA at 230 VAC. The Class II instruments have an IEC 320/C18 AC inlet with double insulation, and enclosure leakage current of as low as 90 µA at 264 VAC. The RoHS-compliant adapters offer standby power consumption of <0.5 W, MTBF of >150,000 hours, an operating temperature from 0°C to 60°C with derating starting at 40°C, and output voltages from 12 V to 48 V with continuous output power of up to 150 W. The devices have a continuous input range from 90 VAC to 264 VAC with 0.98 power factor, and withstand voltages of 4,000 VAC from input to output, 1,500 VAC from input to ground, and 500 VAC from output to ground.
