AutomationDirect's acuAMP line of current sensors now
includes ac ground fault sensors and dc current transducers and switches. The
GFS series monitors current-carrying conductors in grounded single and
three-phase delta or wye systems. Available in fixed-core models, the GFS
series features jumper-selectable setpoints of 5, 10 or 30 mA. The sensors can
accommodate up to 14 AWG copper wire and feature mechanical relay outputs with
either manual or auto reset. The sensors are UL and CE approved.
The DCT series of dc current transducers combine a Hall Effect sensor and
signal conditioner for use in dc current applications up to 400A. Designed to
be compatible with most PLCs, data loggers and SCADA systems, the DCT series
features jumper-selectable current input ranges and 4-20 mA or +/- 10V dc
outputs. Available in split-core or fixed-core models, DCT current transducer
prices start at $117.
DCS100 series dc current switches feature jumper-selectable current input
ranges up to 100A and are available in normally-open solid-state and SPDT relay
output models. The switches are equipped with removable terminal blocks which
accept up to 12 AWG solid or stranded wire.
All acuAMP sensors are panel-mountable; convenient DIN rail adaptor
accessories are also available.
Researchers at the University of Maryland have achieved a first in lithium-ion battery science: the development of a successful lithium-based battery using one material for all three core components of a battery -- anode, cathode, and electrolyte.
The online Bar Steel Fatigue Database for automotive design engineers has been updated for the fifth time and now contains 134 iterations, or grade/process combinations. It provides better predictability for designing parts with long-term reliability and durability.
FPGAs use programmable fabric to create custom logic, but this flexibility comes at a cost -- usually around 10 times more silicon real estate and 10 times the power dissipation. Can we really claim any FPGA is low power?
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
