Able to serve multiple device applications, a medically approved 15 W power supply from GlobTek serves as the backbone power for a rack-oriented modular infusion-pump system. With features such as a leakage current of less than 100 µA, the power supply accepts a voltage from 90 to 264 Vac at an input frequency from 47 Hz to 63 Hz and delivers an output of 12 Vdc at 1.25 A with no minimum load required to maintain output voltage regulation. The power supply has an output load regulation of ±5% and a line voltage regulation of ±1% typ. The turn-on/turn-off overshoot is 5% max, 1 ms typ recovery time for a 25% step load with a hold-up time of 8 ms at nominal voltage and full load. The dielectric withstand voltage is over 5.5 kV from primary to secondary. Able to operate at a high altitude, the power supply is potted for wet-area applications.
The switching power supply meets EN60601-1:2006 Part I, 3rd Edition and complies with EN55011 class B and FCC Part 15 Class B as well as EN60601-1-2:2007 Part 1-2. Additional features include overvoltage and short-circuit protection.
