Acrel ADL400 Installation And Operation Instruction

ADL400
Installation and operation instruction V1.0
1 General
ADL400 is a smart meter designed for power supply system, industrial and mining
enterprises and utilities to calculate the electricity consumption and manage the electric
demand. It features the high precision, small size and simple installation. It integrates the
measurement of all electrical parameters with the comprehensive electricity metering and
management provides various data on previous 48 months, checks the 31st harmonic content
and the total harmonic content, realizes the remote communication and the remote control
with switching input and relay output and boasts the alarm output. It is fitted with RS485
communication port and adapted to MODBUS-RTU .ADL400 can be used in all kinds of
control systems, SCADA systems and energy management systems. The meter meet the
related technical requirements of electronic meter in the IEC62053-21standards.

6 Function description
6.1 Measurement
It can measure the electrical parameter,include U、I、P、Q、S、PF、F、1~31th
harmonic。 Such as:U = 220.1V，f = 49.98Hz, I = 1.99A，P = 0.439kW
6.2 Calculating
Can measure the active energy, reversing active energy, forward reactive energy,
reversing reactive energy
6.3 Demand
The default demand cycle is 15 minutes, slip time is 1 minute.
The meter can measure 4 kinds of maximum demand: forward active, reversing active,
inductance performance reactive, capacitance performance reactive maximum demand
and the occur time.
Demand
Maximum demand Slip time The maximum value of demand in a period of time.
