Cooling and Package Options Ease System Design and Integration

ROAL Electronics today 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 exceptiona. reliability.

The MDP400 is available in three standard output voltages: 12V, 24V and 48Vdc, 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 moise 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 <50 watt load), conduction cooling options, low leakage current and medical approvals make the MDP400 especially suitable for electro-medical equipment.

All MDP400 units are low provile 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 range of -20º to 70º C.

What is Class I Division 2?

Image
A Class I Division 2 is a location: (1) In which volatile flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are handled, processed, or used, but in which the liquids, vapors, or gases will normally be confined within closed containers or closed systems from which they can escape only in case of accidental rupture or breakdown of such containers or systems or in case of abnormal operation of equipment, or (2) In which ignitable concentrations of flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are normally prevented by positive mechanical ventilation, and which might become hazardous through failure or abnormal operation of the ventilating equipment. Class I Division 2 Classification Class I Division 2 refers to the ANSI/ISA 12.12.01 standard. This standard was previously UL1604 until UL recommended the newer ANSI/ISA standard be used and that all hazardous location products be certified under this standa

FUSE SIZING CONSIDERATIONS FOR HIGHER EFFICIENCY MOTORS

Image
When selecting the proper fuse for short circuit protection in motor starting applications, it is important to not only ensure that the fuse will not nuisance open during motor start up times, but also that the fuse will coordinate as required with overload relays. When sizing fuses between 125% and 150% of the motor nameplate current, several advantages, including ease of coordination with an overload device, a smaller disconnect, and increased short circuit protection from a lower fuse rating, can be achieved. However, if sizing at this level prevents the motor from starting, it may then be necessary to increase the fuse ampere rating and it then becomes important to know the NEC sizing limitations. As of June 1, 2016, the US Department of Energy has mandated that newly manufactured electric motors will need to meet NEMA Premium® efficiency standards. As motor efficiencies increase, motor locked rotor currents can also be expected to increase. In addition to this, with across-the-lin

7/8 16UN Connectors that Provide 600 Volts and 15 Amps

TURCK announces new A-Size 3 and 4-pin 7/8 16UN powerfast™ connectors that provide up to 600 Volts and 15 Amps of power. These IP67 rated connectors provide a modular wiring system designed to handle high current applications for machine power distribution, while providing resistance to vibration commonly associated with conveyors, motors and material handling applications. The cordsets are available with a tray rated, exposed run PVC flexlife ® cable, with or without STOOW rating, and 14 AWG wires that allow you to replace hard wiring with a robust, quick disconnect system that saves the time and money spent installing a conduit system. The A-Size powerfast line offers male and female, straight connectors, standard and custom lengths, and pigtails or extensions. To make the system complete, fully encapsulated mating receptacles, with 1/2”-14 NPT mounting threads are available.
