Marsh Bellofram Corp.'sUPA-130S series now includes the "S" model. It is designed to provide
solid-on LED lighting and alert capabilities for those monitoring applications
requiring enhanced NFPA70E and OSHA safety compliance, instead of the flashing
LED's found on the standard model.
The UPA-130S series
is designed to reduce the risk of electric arc flash by pre-verifying the
electrical isolation from outside of a control panel before its re-verification
with a meter. The series operates over a range of 40 to 750V ac (30 to 1000V dc)
line-to-line or ground-to-ground, is phase insensitive and offers high surge
immunity protection. When hardwired to the load side of a circuit breaker or
main disconnects, the UPA-130S series detects stored hazardous ac and dc
voltage in any individual phase. After disconnecting power to an enclosure,
electricians can pre-verify voltage isolation while an enclosure door is still
safely closed. The UPA-130S series offers a potted construction with six-foot
leads and is designed to fit a 30 mm knockout. Its design includes redundant
circuitry and the incorporation of long-life display panel LEDs for extended
use, with components housed in NEMA 4X, 12 and 13 electrical enclosures.
The UPA-130S series is a safety tool for pre-verification of the presence
or absence of residual electrical power or charges, or as a zero energy
indicator, both before or during mechanical lock out/tag out (LOTO) procedures.
It is useful in government project applications, which are typically
characterized by more stringent requirements for solid LED lighting, to avoid
triggering certain medical conditions that can result from visual exposure to
rapidly flashing lights. The UPA-130S series can also be used in
applications such as circuit breaker disconnects, as well as with NFPA 70e
Category III and IV high energy panels; or as an added electrical safety tool
on other types of frequently accessed electrical panels. In addition to its
hazardous area certifications, the UPA-130 is also compliant to CATIII and
CATIV standards, and is CE marked and UL-approved in both the US and Canada.
Almost every automaker has had to 'pick a side' when it comes to alternative fuel options and ways to divest from a reliance on gasoline. Fiat is looking to back compressed natural gas or liquid propane as an interim solution.
Designing and filling a new type of water bottle might take less engineering work, but the description will help kids understand how science, math, and engineering influence their lives even through things that seem mundane.
Against a backdrop of mounting product complexity and a need to keep a lid on development costs, companies are recognizing a need to make simulation a more integral part of the design process. In response, vendors in the CAD world are building out CAE functionality as part of their CAD suites while simulation vendors are building tighter integrations to leading CAD tools. Keith Meintjes, Ph.D., Practice Manager, Simulation and Analysis at CIMdata, Inc., joins Design News CAD Editor Beth Stackpole in this radio program to explore the new face of integrated CAD and CAE, how companies are benefitting from this tighter partnership between platforms, and how integrating CAE earlier in the development cycle pays off in optimized product designs.
