Battery only operation measuring current
and calculated kVA demand profiles
3Ø current recording
This simple method is often very adequate for
determining day/night consumptions patterns,
demand peaks, phase balance and calculating
kVAh totals. In this mode e-Tracker operates
totally from its battery only and has an adjustable
nominal voltage (default setting 415V).
e-Tracker will produce line current profiles and
derive kVA profiles.
Single phase recording
Single phase with the voltage reference derived
from a wall socket etc. Alternatively Tracker will
record current for up to 2 weeks on battery only.
In battery mode Tracker has an adjustable
nominal voltage (default setting 240v.)
Pulse count input (minimum integration period 1 min)
When using the optional pulse input interface,
Tracker can accept a volt free contact closure
from any suitable gas, water or electric metre.
Alternatively the Magpeye optical metre reader
may be connected. Normal analogue inputs are
usable at the same time as pulse input.
