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.
A middle school team from Rochester, Mich., has again nabbed the grand prize in the annual international Future City Competition, which drew students from 37 regions of the United States, as well as from England and China.
The word “smart” is becoming the dumbest word around. It has been applied to almost every device and system in our homes. In addition to smartphones and smart meters, we now hear about smart clothing and smart shoes, smart lights, smart homes, smart buildings, and every trendy city today has its smart city project. Just because it has a computer inside and is connected to the Web, does not mean it is smart.
Are you being paid enough? Do you want a better job? According to a recent survey Manpower released just before Engineers Week, employers and engineers don't see eye-to-eye about the state of US engineers' skills and experience.
