New Style STS Split Din Rail Type Single Phase Prepaid energy Meter
With Keypad
The DDS5558 is a Din Rail mounting split type single-phase
prepayment meter operating with STS standard encryption algorithm.
It is available with option for SMPS sustaining power supply,
enabling the meter to work with stable performance even in
brownouts, making it a sound revenue controller suitable for
constantly unstable grid.
The meter operates in two parts: MCU, Metering Control Unit, and
CIU, Customer Interface Unit. The CIU is a tactile and audible
keypad with LCD display, normally installed under consumer's roof.
The MCU, or the main meter is usually installed in a secure, locked
enclosure-typically a pavement kiosk or pole-mounted equivalent. It
is outside the consumer's premises to faciliate easy inspection by
the utility at any time, thus reducing the possibility of
tampering.
Thanks to the slim-line size and DIN rail housing, mutiple
Power-Rail meters can be mounted in a small enclosure thereby
making installation cost effective. It is ideal for installation in
Granny Flats, Individual Rented Unit, Shops, Stores and sporting
Facilities.
Connection between the meter and CIU is via a pair of
communications wires. The MCU contains all critical metering,
encryption, decryption and load control functionality. It operates
independently of the customer interface unit and is immune to any
form of tampering on the customer interface.
