4.4. EMI
4.4.1. CONDUCTED EMI
For 240 Vac input operation, the power adapter must below the CISPR 22,
Class B limit for HF equipment and DP equipment with a 3 dB margin. For 120
Vac input operation, the power adapter must below the FCC part 15 sub–part B
for Class B computing device with a 3 dB margin. For 100 Vac operation, the
power adapter must below the VCCI limit by a 3 dB margin. Both conducted and
radiated emissions shall be measured in the applicable system and complied with
the required standards.
4.4.2. RADIATED EMI AND EMC
No peak emission in the frequency range 30 MHz to 1G Hz shall exceed
Class B limit when measured per ANSI C63.4, CISPR 22 and VCCI measurement
procedure.
4.5. TEMPERATURE RISE
The maximum temperature measured at any point on the enclosure surface shall
not exceed 70℃ at room temperature of 25℃ i.e., the maximum temperature rise
on the surface of enclosure shall not exceed 45℃.
4.6. SURGE WITHSTAND AND EFT
The power supply shall withstand the line transient for both Common Modes at
2KV and Differential Mode at 2KV operations.
5. RELIABILITY
5.1. MEAN TIME BETWEEN FAILURES (MTBF)
The MTBF for the power adapter shall equal or exceed 50,000 hours when
operated at full rated load in an ambient temperature of 35℃, and 100,000 hours
when operated at full rated load in an ambient of 25℃ by MIL-HDBK-217F.
6. DIELECTRIC WITHSTAND TEST
6.1. HI-POT
Primary to secondary 4242Vdc for 1 minute
6.2. LEAKAGE CURRENT
3.5 mA Max., at 230 Vac input.
