Low noise encapsulated power supply for medical applications

Gresham Power has introduced a new series of low noise AC/DC converters for medical applications. The P3/P5/MHIA Medical AC/DC linear power supply series from Polytron Devices is UL 60601-1 Third Edition recognised. The 2MOPP compliant linear encapsulated AC-DC power module is suitable for applications including surgical equipment, patient monitoring, imaging, laboratory and diagnostics equipment. These single, dual and triple output power supplies provide 4000VAC reinforced insulation and are available with either a PC mount or chassis mount footprint with screw terminal connections,. The series delivers an extremely low output noise of 1mV rms while providing a 2µA patient leakage current and a regulation line and load of 0.02% to 0.2%. In addition, these models feature short circuit protection, CE certification and optional international input voltages including dual and switchable. Output voltages are available over the range 55VDC-250VDC for single outputs, +/-5VDC to +/124VDC for dual outputs and 5VDC +/-12VDC and 5VDC +/-15dc for triple output units.
