Eaton Introduces ePDU G3 with New Fast-turn
Eaton has announced
for its ePDU third-generation (G3) platform in the
Americas. Building on its
portfolio of rack power
distribution units (PDUs),
Eaton's customizable ePDU
G3 models are designed
for fast turnaround of
outlet and cord plug
the flexibility for data centers and co-location facilities to quickly
address their specific power distribution needs.
Eaton has invested in three-axis routing and laser etching
equipment to streamline the manufacturing of ePDU G3 custombuilt models. The technology further increases customization
speed and efficiency, enabling quick initiation of design to fabrication processes. Eaton's manufacturing platform also includes new
automated test equipment that provides 100 percent functional
testing to all ePDU G3 models, which is designed to eliminate human error and ensure quality and reliability.
Highlighted by enhanced technological features, the ePDU G3
is built with an aluminum chassis that is strong and lightweight.
Network connected ePDU G3 models can daisy chain with other
PDUs, so that four devices can share one network port and IP
address, reducing network connection costs by 75 percent. Additionally, the ePDU G3 features a new patent-pending IEC outlet
grip designed to eliminate the common and often costly problem
of plugs falling out of IEC outlets due to bumps or vibrations. This
can protect data center and IT managers from incurring additional
expenses related to purchasing special power cords or cable trays,
which can increase PDU costs up to 50 percent.
Eaton ePDU G3 models EMI319-10 and EMI320-10 offer
customization capabilities for 400-volt power distribution, ideal
for optimizing energy efficiency in three-phase data centers and
colocation facilities. Engineered for smaller data center deployments and medium-to-high-density IT equipment in computer
rooms, Eaton ePDU G3 model EMI200-10 offers 120- and 208-volt
distribution from the new Eaton 9PX SP split-phase uninterruptible
power system (UPS).
Bourns Introduces Surge Protective Device for
Sensitive Signal and Data Line Applications
Bourns, Inc. has added a surge
protective device (SPD) for signal
and data line applications to its
portfolio. Designated Bourns Model
1840, the device is a MSP MultiStage Protector designed to safeguard sensitive electronic circuits
and components from damaging
surge voltages and currents.
The model features extremely
fast response and low clamping
voltages making it well suited to
protect signal and data lines associated with computer, data communication, instrumentation, broadcasting and industrial controls.
The Bourns Model 1840 supports working voltages of 5, 12 and 24
volts, and may be used directly with RS-232, RS-422, RS-423 and

RS-485 standard EIA interfaces as well as with 4-20 mA and 50 mA
Bourns' solid-state, third stage protection device works by
intercepting the leading edge of a surge within a sub-nanosecond
response time. Within micro-seconds thereafter, a primary stage,
three-electrode common-chambered Gas Discharge Tube (GDT)
activates and crowbars the majority of the surge energy to ground.
The new model also utilizes Bourns TBU High-Speed Protector (HSP) technology as a key second stage. Currents exceeding
300 mA through the protector will cause the TBU HSP to quickly
transition into high impedance, isolating any harmful voltages and/
or currents from damaging the protected equipment. The GDT
protector remains in the crowbar state until the surge has passed
and line voltages return to safe levels. After an event, the TBU HSP
automatically restores the line to normal operation by automatically resetting to a low impedance state.
The Bourns Model 1840 features vibration-resistant screw-type
clamp terminals and convenient mounting and grounding is possible to any flat surface or to DIN-1 (TS-32) or DIN-3 (TS-35) rails.
The device also has a flame-resistant epoxy-filled housing and
cable shields are passed through and may be grounded or arcprotected to ground.
Powerstax Offers New Conduction Cooled COTS
Powerstax has added two switch-mode COTS DC-DC power supply units to its portfolio, which are designed to cope with demanding application
is a rugged,
Vita 62 compliant unit that accepts a wide range 28 VDC input. It is 600 W DC
rated across five outputs.
These outputs offer 12 VDC at 40 A, 5 VDC at 24 A, 3.3 VDC at
15 A, -12 VDC at 2A and +12 VDC at 1 A, with the unit's 12 VDC
output capable of being paralleled in order to attain higher power
or for the purpose of including redundancy. The advanced XtraCooling technology dissipates heat from the unit and maximizes
operational longevity. The VPXtra 1000CM has no minimum load
requirement and boasts extremely effective over-voltage, overcurrent, short circuit and thermal protection features. Its inputto-output isolation covers up to 500 VDC, while its line and load
regulation are 0.5 percent and 1.0 percent respectively.
To complement this, Powerstax now also markets the VPXtra
1000CD - a dual output COTS DC-DC unit that has the same wide
range 28 VDC input as the VPXtra 1000CM along with an identical card edge conduction cooling mechanism, but delivers up to
1,000 W of clean, regulated 12 VDC output power and 3.3 VDC
auxiliary power. Both these units are targeted at deployment in
mission-critical airborne, shipboard, vehicle and mobile VPX power
applications, as well as high-end industrial hardware. They are IAW
