MD Series of Medical-Grade Power Sources

Triad Magnetics introduces the MD series of rugged, portable medical‐grade power sources. The units, complete with power cord and receptacles, provide a simple and reliable means for safely isolating medical devices, including patient interface apparatus, diagnostic instruments, patient monitoring equipment, and electrical stimulus therapeutic equipment, from the power line. The MD series is available in models with output voltage of 120 V_AC in ratings from 250 VA to 2400 VA, with two or four NEMA 5‐15 receptacles (based on VA rating). Units are available with 240 V_AC or 120 V_AC input. All units feature 3 kV galvanic isolation, 5% no‐load to full‐load regulation and 92% minimum efficiency at full load, and less than 10 μA typical leakage. The construction of the MD series toroidal transformer minimizes leakage currents from the power line through to the patient and equipment. It also minimizes radiated magnetic fields that can adversely affect very sensitive patient diagnostic, monitoring, and therapy instruments. The MD series offers users (hospital and medical center personnel) the capability of providing medical‐grade power to several different instruments within the space of a patient’s room.
