Per MIL-HDBK-217F, that MTBF is >600,000 hours (+25oC Ground Benign) and greater than 125,000 hours for Airborne Inhabited. The 1800 series has been designed specifically to meet the rigorous demands of avionics equipment. Eight models have wide 16 VDC to 36 VDC inputs, centered on 28 VDC. Single, dual or triple output combinations of 5, 12, 15, ±5, ±12 and ±15 VDC are provided. Standard features include 1000 VDC input/output isolation, output ripple and noise of less than 1% and continuous short circuit protection. Efficiency is as high as 80%. A remote ON/OFF control input and internal PI filter are standard. Long field life is insured by extensive reliability screening at Martek Power. All 1800 series units are designed to the requirements of MIL-STD-202 and MIL-STD-810. As part of the normal production processing, each unit is subjected to 72 hours of burn-in with power cycling and load switching. The 1800 series converters have been qualifed and meet MIL-STD-704D emergency power conditions for aircraft, and MIL-STD-461C and MIL-STD-1275A for EMI and transient protection. Compliance to the EMI standards of MIL-STD-461C (including CE01 and RE01) is achieved without the need for external filtering components. Each 1800 model is packaged in a very low profile 2.56 x 3.0 x 0.4 inch metal case. Six-sided continuous shielding insures each converter meets the requirements of VDE 0871 Class B for radiated emissions. Full operation is specified over the wide temperature range of -55oC to +85oC with no derating or heatsinking required. Cooling is by free-air convection. Martek Power’s 1800 series has been designed to meet the military standards applicable to avionics applications. For specific information on test methods and/or test levels or our own reliability processing, please contact the factory. Some of the applicable military standards include: MIL-STD-810E This standard establishes the methods of testing the effects of natural and induced environments on equipment used in military applications. MIL-STD-461C This stnadard sets the design and documentation requirements for controlling the electromagnetic emission and suseptibility characteristics of electronic equipment. MIL-STD-202E This standard outlines the test methods for determining a components’ resistance to the effects of natural elements and conditions. Typically used on small components such as resistors, capacitors and transformers. Tests numbered 300 thru 399 cover electrial characteristics. MIL-STD-1275A This standard describes the transient voltage characteristics and steady state limits for 28 VDC powered circuits used in military vehicle. MIL-STD-704D This standard defines the conducted electrial power characteristics for aircraft systems at the interface between the power system and electronic equipment. It insures the compability of aircraft electric systems and ground support >> 1 www.make-ps.com OUTPUT CHARACTERISTICS Voltage & Current Ratings 2 Output Voltage Accuracy Single/Dual Output Models Triple Output Models Voltage Adjustment 3 Voltage Balance 4 Dual Outputs Triple Outputs (Aux.

SPECIFIATION NOTES 1 2 Shock Vibration Altitude Humidity Switching Frequency 3 4 5 6 7 = The max. input range of 16 to 50 VDC is specified for 250 mS (Per MIL-STD-704D). = Total output power should not exceed 16W. The load on any auxiliary output should not exceed 500 mA. = Outputs are adjustable on single and dual output units only. = Voltage balance is measured with balanced loads applied. = Transient response is measured on the primary output for a 50% load change (50% load to full load). = Efficiency is specified at nominal input line and full load. = These converters have a thermal resistance of 2.1 oC/W (Internally dissipated). The internal thermal protection circuits are trigged if the case temperature exceeds 95oC. Maintaining the module case temp. below 95oC can be accomplished by mounting a low thermal resistance heat sink (with vertically orientated fins) to the case with a thermally conductive compond. This will significantly increase heat transfer from the module to the ambient. Forced convection cooling can also be used. The amount of cooling will depend upon the flow of air in linear feer per minute (LFM) over the module. >> 2 www.make-ps.com ENVIRONMENTAL SPECIFICATIONS Operating Temp. Range Storage Temp.
