b) Overcurrent Protection: The power extend converter shuts down
(opens the output) if output current exceeds 24 A. The power
extend converter goes into overcurrent protection. Manual
restart is required by turning the power extend converter off and
then back on after the overcurrent condition has been corrected.
c) Over Temperature Protection: The power extend converter
shuts down if the internal temperature of the power extend
converter exceeds an acceptable level. Boost conversion
operation will automatically resume after the over-temperature
condition is corrected.
4. Hot Swappable: The power extend converter is designed to be plug-
and-play. The power extend converter can be inserted or removed
from a live DC power system with no damage as long as the power
extend converter is inserted with the enable/disable switch in the
disabled position. Plugging the power extend converter into the
system will not affect the system voltage.
5. Load Sharing: Power extend converters are capable of being
operated in parallel and share the load such that the maximum
difference in output current between any two converters is less than
2.5 A. For loads exceeding 1000 watts, the rate of change of current
to the load must be less than 2 amps per millisecond at startup to
prevent actuation of the over-current protection feature. Once the
output voltage of the converters has reached steady state (58 VDC),
the Dynamic Response specification will be met for units operating in
parallel. Refer to the specific mounting bracket kit instructions (see
Table 3
) for spacing and power restrictions. See
Table 3
for
paralleling power extend converter instructions.
6. External Alarm Contact: A power extend converter fail alarm contact
is extended to the distribution device alarm termination strip on the
distribution panel.
7. Local Controls: A switch is provided on the front of the power extend
converter to enable/disable operation.
8. Local Test Points: Test points are provided on the front of the power
extend converter to allow measurement of output voltage.
