AC/DC POWER MONITORING
Asentria’s power monitoring devices put the power in your hands. Measure
voltage, current, and total power in DC power systems; and in single-, split-, and
three-phase AC power systems. Select from a wide variety of power-measurement
sensors to  t your needs. Attach them to your Asentria base unit to detect and
correct site power problems early, BEFORE they become major problems.
* Some accessory devices output signals are compatible only with certain
Asentria base-unit models. Also, some accessory devices require an
external power supply. Contact Sales for more details.
• AC Power Monitor (ESS-APAC) - Monitor up to 3-phases of
main power and backup power, measure overall power usage,
power quality.
• AC Current Monitor (ESS-TCAC, ESV-TCAC) -Monitor and measure
AC current  ow on single- or three-phase systems.
• DC Current Monitor (ESV-TCDC) - Monitor and measure DC current
 ow for entire site or components; calculate power usage
• AC Voltage Monitor (ESM-TVAC) - Monitor and measure AC
voltage levels
• AC Voltage Detector (ESV-SVAC) - Check presence of AC power
• AC Current Detector (ESC-SCAC) - Monitor component on/off status
via AC current  ow
AC/DC POWER MONITORING APPLICATIONS*
AC Monitoring example where the AC power Monitor is connected to the rectifi er
and the circuit box and is passing data to the SiteBoss unit. This data can take the
form of usage, on/off, etc.
AC POWER MONITOR
This AC power monitor provides accurate
three-phase AC measurements, as well as
comprehensive per phase information, including
Volts, Amps, Real Power, Reactive Power,
Apparent Power, Watt-hours, VAR-hours, VA-
hours, Power Factor, and Frequency. Works with
Asentria base units that have scripting capability.
Script to read RS485 protocol needed on base
unit. UL/CE listed.

CURRENT TRANSFORMERS
Current transformers scale high input AC currents into a
usable output range for AC monitors. Current transformers
differ in their output current, and must be matched to the
correct transducer. These mA-output current transformers
are optimized for use with the ESS-APAC1, ESS-APAC3
and ESS-TCAC1. There are two styles: solid-core and split-
core. The split-core style opens to clamp over a power wire without disconnecting
it from its source. Sensor wiring kit (/K25) sold separately.
