COSEL Co, Ltd has added a new series of high isolation 6W DC-DC converters for medical, industrial and ICT applications. The COSEL MH is a unique design from the company and is covered by a five-year warranty. The COSEL MH6 series package is SIP 8 type, provides reinforced isolation of 3kVAC and 4.2kVDC, meets medical isolation standards (2MOOP (250VAC working voltage)), and is rugged and suitable for industrial applications where in/OUT differential pressure may exist. Three input voltages (4.5V-18V; 9V - 36V and 18V - 76v) and a variety of single (MHFS6) and dual outputs (MHFW6) cover a wide range of applications. According to the performance design, the maximum insulation capacitance of MH6 is only 20pF, which reduces the noise transfer.
With extensive expertise in designing IGBT driver device power supplies, its designers have applied high power high isolation best practices to the low power 6W MH6 series to reduce isolation fatigue caused by differential high voltages that occur in motor control or IGBT drivers. And the series features high reliability, reinforced insulation, supports 3kVAC and 4.2kVAC isolation tests according to safety standards, and its transformers are designed to maintain differential voltages that can occur in industrial applications.
The company therefore conducts testing and validation and provides life expectancy curves to support system architects developing gate controllers for industrial equipment to apply the appropriate design rules and considerations in the application note.
This power supply complies with the RoHS directive and is CE marked and complies with The Low Voltage directive. And in order to reduce the user's board space, the series is housed in a SIP8 package with a size of 26mm x 12mm x 5mm [1.03" x 0.48" x 0.38"] (WxHxD) and a maximum weight of 8g
