"Designed to meet industrial requirements, with built in high Ingress Protection
(IP) for harsh environments, the Powerbox’s three-phase ENI250A is not only a
robust and efficient power solution but a mechanically reconfigurable platform
able to fit different form factors or even direct integration into DC motors"

T
he Powerbox three-phase
ENI250A series is housed in an
IP54 case, delivers a constant
250W and up to 480W peak power with
an efficiency up to 94%. The ENI250A
includes a microcontroller that offers
many possibilities to adjust protection
behavior to meet specific customer
requirements.
Factory automation is already well
established in many industries, but with
the progress in Artificial Intelligence (AI),
remote communication and the growing
demand for shorter customer lead times,
it is predicted to explode in coming
years. Similarly, the growth of automated
parcel-hubs is expected to rise
spectacularly. The rapid development
of e-commerce has contributed to the
creation of highly automated hubs with
conveyers, sorting switches and many
other equipment requiring efficient and
intelligent power solutions able to work
in demanding environments.
Parcel hub-designers and hub-operators
are facing multiple challenges in having
to deal with a large variety and types
of equipment. This not only requires
high quality, high performances power
supplies, but the ability to operate in
32
harsh environments with a complex mix
of mechanical, thermal and electrical
constraints.
Addressing 24VDC motors, the
250W ENI250A24 can deliver 480W
peak power for one second, sustain
high capacitive loads and manage
energy recycling when a DC motor is
decelerating or stopping. This function is
very important for energy saving and to
increase equipment life-time. For higher
power or redundancy, the ENI250A24
can simply be paralleled. The unit has an
operating temperature range from -25 to
+70 degree Centigrade.
Other output voltages are available
on demand to power 36V, 48V DC
motors, as well customized voltages.
The ENI250A24 includes soft-start,
over current, voltage and temperature
protection. An LED indicator informs
the status of the power supply and a
DC-OK signal and remote reset provide
for easy integration within the conveyer
operation management system. It is
designed using Powerbox’s reliable
power platform concept and uses an
active power factor correction (PFC) in
combination with a high efficiency and
compact LLC topology.
Exhibiting versatility, the ENI250A24
accepts input voltages from 323VAC to
560VAC three phase, and is designed
to meet safety specifications 60950-1
and 62368-1. EMC is in accordance with
EN61000-6-3 and EN61000-6-2.
Housed in an IP54 case, the ENI250A24
has dimensions of 250x160x55mm,
weighs 1.5Kg and mounting brackets are
available for easy installation. Designed
for easy integration within customers’
equipment, the ENI250A platform can
be factory re-configured to fit specific
form-factors.
