Circuit Breakers
Circuit breakers protect the power controller and all devices connected to it from fault conditions, such as a
short circuit or an overload. Circuit breakers are optional for ePDUs with less than 30A input. However, circuit
breakers are mandatory for ePDUs with 30A input or greater.
!
IMPORTANT
If a supplementary protector is used in the ePDU instead of a listed circuit breaker, additional
branch circuit protection is required down-line from the power source to the ePDU.
Power Outlets
All outlets are on the rear panel. Power is available to the switched outlets after the main power is either
connected or the optional breaker is set to the ON position.
Auto-Transfer Primary to Secondary
Firm drop-out voltage points allow a transfer before an undervoltage affects equipment operation.
Table 2 shows the transfer voltage ranges.
Sources do not need to be phase synchronized. Source transfer time is less than 30 ms. (The front panel LEDs
indicate which sources are available and selected at the output, as shown in Figure 5.)
Optional EMI/RFI Filtering
EMI/RFI Filtering (Option 3)
Power filtering reduces the effects of EMI or RFI. This type of “noise” can be introduced from many sources,
inside or outside your facility. The filtering is bi-directional, so it helps prevent emissions from connected
equipment. Select “F” in Option 3 to include EMI/RFI Filtering or “N” to exclude it.
Table 3 shows EMI Filter Specifications.
