6W DC-DC converter has 4kVdc isolation for medical designs
Cosel in Japan has launched a high isolation 6W DC-DC converter series for medical, industrial and ICT applications.
The MH6 Single In Line (SIP) type 8 family has a reinforced isolation of 3kVac and 4.2kVdc and complies with the 2MOOP medical isolation standard. The transformer in the DC-DC converter is designed to sustain differential voltage that might occur in industrial applications.
The MH6 DC-DC converter is available in three wide-input range voltage: 4.5V to 18V covering 12V battery applications, 9V to 36V combining 12V and 24V battery systems and 18V to 76V addressing 24V and 48V systems.
It has five single output options at 3.3V, 5V, 9V, 12V, 15V (MHFS6) and two dual outputs +/-12V and +/-15V (MHFW6). Output can be used in series, delivering 24V or 30V. Single output voltage MHFS6 can be adjusted by using the Vout Trim pin on the secondary side.
The MH6 series has built-in overcurrent protection circuit, with automatic recovery. A remote control pin operating as negative logic (L:ON, H:OFF) is available on standard, and 20pF max insulation capacitance to reduce noise transfer in motor controls.
The MH6 series can be operated within a temperature range of -40 to +85C ambient, 20 – 95%RH (Non condensing). Depending on cooling, a power derating may apply to not exceed +105C at specified measuring point.
The MH6 series pins are molded in an epoxy holder, strengthening the connections between the application PCB and the module, making the unit even more reliable when used in demanding applications. It has been qualified on vibrations testing: 10 – 55Hz 98.0m/s2 (10G), 3minute period, 60minutes each along X, Y and Z axis and shock: 490.3m/s2 (50G) 11ms, once each along X, Y and Z axis.
The SIP8 package measures 26.0 x 12.0 x 9.5mm (1.03 x 0.48 x 0.38 in) and weighs 8g. The DC-DC converter series also has a five year warranty.
