Mobile Radio (Helicopter)

A professional mobile radio, used for civil and military communications, emergency services, aid, vigilance and control, is powered by Vicor. The modules provide mechanical and thermal ruggedness, correct temperature and humidity ranges, Radio Frequency Susceptibility (radiated and conducted) performances, high-efficiency, and shock and vibration resistance. The European Organization for Civil Aviation Electronics (EUROCAE), who works jointly with RTCA in the development of standards, defines a series of minimum standard environmental test conditions and applicable test procedures for airborne equipment. The purpose of these tests, which last 20 days, is to determine the performance characteristics...

New Mid-Power 48 Vin Micro Modules

Vicor has added six mid-power Micro DC-DC converters to the 48 Vdc input family: a 50 W model at 3.3 Vout and 75 W models at 12, 15, 24, 28, and 48 Vout. The modules – which incorporate Vicor’s patented low-noise zero-current and zero-voltage switching (ZCS/ZVS) – are appropriate for power system applications in distributed power, medical, ATE, communications, defence, and aerospace. With these new models, the 48 Vin Micros family now comprises 16 models with output voltages from 2 to 48 Vdc and power levels from 50 to 150 W. The converters operate...

New Mid-Power Micro Modules

Vicor has added seven mid-power Micro DC-DC converters to the high-density 300 Vdc input family: two 50 W models, one at 3.3 Vout and 5 Vout, and five 75 W models at 12, 15, 24, 28, and 48 Vout. The modules are appropriate for designing off-line power systems for industrial and process control, distributed power, medical, ATE, communications, defense, and aerospace applications. The addition of these modules doubles the size of the high-power density 300 Vin Micro family, which previously consisted of 100 W at 5 Vout, and 150 W at 12, 15, 24,...

New Tram-Trains Using Tyres

This new rubber-tyred vehicle system takes bus and tramway and combines the advantages of the two systems: better stability, a smoother ride for travellers, only one central rail, more flexibility and, with a diesel engine, it can be used on every road. Vicor modules (VI-J00 products) are used in this modern system of transportation. With a wide input voltage range of 18 – 36 Vdc, a high reliability (MTBF), low size and weight, and ease of use, the Vicor modules provided the ideal solution.

Vicor is Now Shipping RoHS Compliant Products

January 4, 2006
By

Customers using Vicor products can decide for themselves the date that they wish to transition to RoHS compliant manufacturing processes. Whilst the European Community has established a date of 1st July 2006 for full RoHS compliance, some customers may wish to transition immediately whilst others in market areas such as Defence and Telecoms, which are generally excluded, may wish to delay transition. For our first generation VI-200 and VI-J modules Vicor has introduced new VE- part numbers that allow customers to specify RoHS compliant product. For our 2nd Generation products, specifying a -G suffix...

In a recent application, the customer used two DC-DC converter modules, in parallel with current sharing and battery charging circuitry to provide power from a high voltage battery to the Smart Car’s standard 12 V electric system. The 316 Vdc battery is fitted in an insulated container under the car’s floor to provide traction via compact electric motors, instead of the normal petrol engine. In short, Vicor modules are being used as a solid-state alternator. Although the car has a small 12 V battery, to supply peak power and emergency back up, the two modules...
