Cooling and package options ease system design and integration

MDP400Castelfidardo (AN), Italy – November 14, 2011 – ROAL Electronics announced a new family of very efficient and compact Medical power supplies. The MDP400 series has several package options including open frame, U-chassis, enclosed chassis, and environmentally sealed IP65 rated versions. Compliant to Energy Star 5.0 criteria, the series generates minimal heat facilitating outstanding thermal management in space constrained systems with exceptional reliability.

The MDP400 is available in three standard output voltages: 12, 24 and 48 Vdc, and includes auxiliary 12 Vdc and 5 Vdc standby outputs. The product dissipates <0.5 watts in standby mode, and the integral fan speed control minimizes audible noise while maximizing useful life. The MDP400 series complies with the 3rd edition of the UL/IEC60601-1 safety standards for medical equipment. Low/no noise fan operation (fan is off <50W load), conduction cooling options, low leakage current and medical approvals make the MDP400 especially suitable for electro-medical equipment.

All MDP400 units are low profile and compact with open frame version dimensions of 3” x 6.46” x 1.48” (76mm x 164mm x 37mm). The packaging options permit all standard cooling methods including convection, forced air or conduction (baseplate) cooling across an operating temperature range of -20 to 70 C.

24Volt and 48Volt models will be available from stock in early 2012. OEM prices start at 90 euros per unit.
