The GT(M)91099 series of desktop power supplies feature mechanical configurations with double-reinforced insulation, regulated output voltage of 12–24 V dc in 0.1-V increments, and as much as 60 W of continuous output power. The enclosed power supplies are housed in an impact-resistant, nonvented polycarbonate case measuring 118.5 × 53.5 × 34.2 mm and including thermal conduction cooling. The supplies provide regulated output with very low ripple; come with overcurrent, short-circuit, overvoltage, and thermal protection; and accept universal input of 90–264 V ac. They meet international safety agency requirements in accordance with IEC 60950 and IEC 60601.1 for medical and information technology equipment applications, comply with appropriate regulations for electromagnetic and radio-frequency interference, and are CE marked. Modified and custom designs are available.
