The MH3 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. Devices 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.
To reduce transfer noise, the isolation capacitance is reduced to the lowest possible level, reaching a maximum of 20 pF, which is a great benefit when powering motor control systems.
To reduce user’s board space, the MH3 series is housed in a SIP8 packaging measuring 22.0 x 12.0 x 9.5mm [0.87 x 0.48 x 0.38 in] (WXHXD) and has a weight of 7 grams maximum. Industrial and in some case medical equipment can be subject to vibrations engendering possible damages on the pins of SIP products. The 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. The DC-DC converter series 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.
Addressing both, medical and industrial applications, the series conforms to UL62368-1, EN62368-1, c-UL (equivalent to CAN/CSA-C22.2 No.62368-1), ANSI/AAMI ES60601-1, EN60601-1 3rd, c-UL (equivalent to CAN/CSA-C22.2 No.60601-1).
The power supply complies with the RoHS directive and is CE marked in accordance with the Low Voltage Directive.
