Class 1S Accuracy Commercial Electric Meter MCB Single Phase Power
Meter
The CA168-E is a single phase keypad based STS prepaid meter with
extended cover and available with connection to MCB.It is intended
for a broad rang of prepaid applications, With an improved dynamic
current range allowing a basic current of 5 Amp while keeping a
maximum current of 80 Amp and extended functional features, CA168
is provided with a BS5685 standard housing and maintains the
anti-tamper features, allowing it to be installed in harsh
envrionments.
The meter is attached with a metal backplate that can tightly fix
the meter body agaisnt the mount surface to reduce the tamper and
sabtage. CA168 thus is a perfect solution for low voltage small home
consumers and are ideal for retrofit applications. The feature rich
device provides enhanced tamper protection, as well as settable
power limit and reverse energy measurement.
As tamper as the major cause of non-technical loss, Calin's prepaid
meters are all provided with anti-tamper features. The meter is
equipped with sensors and triggers. Any illegal intrusion will
trigger visual and audio alarm and the inside contactor will
consequently disconnect the power if the user not compromise within
preset time period. The tamper will be recorded as an event stamped
with time within meters' non-volatile memory as proof for future
data retrieval.
