Aurora, OH: Network Technologies Inc (NTI) today announced the
addition of an AC and DC Voltage and Current Monitor to its popular line
of environment monitoring sensors. The sensor can be used to measure
and report AC and DC voltage, report AC and DC current, and is
compatible with the ENVIROMUX-2D/5D/16D Enterprise Environment
Monitoring Systems.
The ENVIROMUX-ACDCLM measures and reports AC and DC voltage, and
reports AC and DC current measured with attached Hall-Effect transducers
(sold separately). Current measurements require Hall-Effect
transducers. With a polling rate of 1Sa/s, the unit features an AC
voltage 2-pin terminal block, a DC voltage 2-pin terminal block, one
rectifying Hall Effect 4-pin transducer interface for measuring AC
current, and one rectifying Hall Effect 4-pin transducer interface for
measuring DC current. Accuracy and range for current measurement is
dependent on the transducer used.
Common applications for hall-effect sensors include: monitoring AC
variable speed drives, static converters for DC motor drives, battery
supplied applications, uninterruptible power supplies (UPS), switched
mode power supplies (SMPS), electrochemical systems, and power supplies
for welding applications. NTI offers two types of hall-effect current
sensors, solid-core and split-core. Solid-Core ENVIROMUX-AMPxx-6-5
transducers are available in rated currents of 10A, 20A, and 50A, with a
loop diameter of 0.26" (6.5mm). Split-core ENVIROMUX-AMPxx-SC21
transducers are available in rated currents of 30A, 50A, 100A, 200A, and
500A, with a loop diameter of 0.83" (21mm).
The ENVIROMUX-ACDCLM connects directly to the ENVIROMUX-2D/5D/16D
Enterprise Environment Monitoring System via a single CAT5/5e/6 cable up
to 1,000 ft (305m) away. The Hall-Effect Current Sensors include a 7-ft
4-wire cable for connecting to the ENVIROMUX-ACDCLM, but can be
extended by connecting longer wires using the included splices.
