INTRODUCTION

The A1100 is an electronic polyphase meter for domestic, commercial and light industrial CT or direct
connected applications.
Two main versions of the A1100 meter are available. The liquid crystal display version of the meter
can be supplied with one or two rates. The meter is available as import only or import and export.
The display has a customer defined display sequence that can include security information.
Chevrons and legends on the nameplate identify the data being displayed.
The stepper register version of the meter is available for kWh import one rate applications only.
Five LED's are used to identify the status of the meter/system.
Communication is provided via the IrDA (Infrared Data Association) port allowing the meter registers
and security data to be read electronically using a hand-held device. This greatly reduces the possibility
of manual meter reading errors. The meter can be configured at manufacture to provide the same
absolute serial data as the IrDA port via the meter auxiliary terminals.
As an alternative to serial data the auxiliary terminals can be configured at manufacture to give SO type
kWh consumption pulses.
Automatic Meter Reading (AMR) is facilitated by either the IrDA port, serial data stream or the pulsed
output. AMR allows the meter to be read remotely by either radio, mains signalling or over a telephone
line. Fast, accurate meter readings can be obtained for use in energy management systems.
Meters can be supplied to meet accuracy Class 1 or Class 2 requirements.
