As a result, the "battery-powered" interferences are unable to be managed, resolved or prevented by conventional remedies such as MOVs (metal oxide varistors), tranzorbers, zener and avalanche diodes, passive filters, capacitors, fuses, circuit breakers, etc. which are used to protect electronic equipment. The MIL-STD-1275B sets the requirements that all 24VDC "battery-powered" equipment must be compliant in order to ensure reliable and fault free operation. Although complying with the MIL-STD-1275B is mandatory in military applications, it is highly recommended to be adopted in any type of "battery-powered" equipment. The MIL-STD-1275B addresses 3 major interferences: 1. Surge-40V 2. Surge-100V 3. Spike-250V 2 www.DataSheet4U.com Elmo Compliance with MIL-STD-1275B Surge-40V Electrical System Requirement Equipment shall continue to operate normally throughout these tests without damage t...
