Triad’s MD Series Portable Power Source Offers 3kV Medical-Grade Isolation

Feb16_TriadTriad Magnetics has introduced 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 , 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 VAC 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 VAC or 120 VAC input.  All units feature 3 kV galvanic isolation, 5 percent no-load to full-load regulation, and 92 percent typical 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.

“Our MD series toroidal transformer design does not include additional and often unnecessary filtering circuitry which simplifies the device and makes it more reliable while lowering cost,” said Triad’s CEO, Bill Dull. “And unlike most of the competitive units that have the output neutral wire tied to ground, the MD series output neutral is floating, effectively limiting chassis leakage current as well as ground leakage current.”
