Q: What’s the difference of current input via direct connect or via CTs?
A: Normally, for 3-phase loads with rated current below 80A AC, we will use model of ADL400 whose current input is via direct connect. Specs of “Rated Current: 10(80)A AC” was aimed for this model of ADL400 (current input via direct connect). 10 means basic current is 10A AC, 80 means rated current input is 80A AC.
And for 3-phase loads with rated current over 80A AC, we will use model of ADL400 whose current input is via CTs (usually paired with -/5A CTs whose secondary current output is with 5A AC rated current output). Specs of “Rated Current: 1(6)A AC” was aimed for this model of ADL400 (current input via CTs). 1 means basic current is 1A AC, 6 means max current input is 6A AC.
Q: Do your company also have paired CTs for ADL400?
A: Usually, we will recommend our user to use split-core CTs called AKH-0.66/K K-φ Series or solid-core CTs called AKH-0.66/I Series to the paired with ADL400 (current input via CTs)
Q: How can I set the CT or PT ratio of ADL400?
A: Current ratio of ADL400 could be set by using the keypads on ADL400 and following the instruction of ADL400 manual. Also, setting need to be according to the CTs or PTs ratio which were paired with ADL400. For example, if the current input is via 250A/5A CTs, the CT ratio on ADL400 should be set to 250/5=50. And if the voltage input is via direct connect, PT ratio on ADL400 should be set to 1. When the problem hasn’t been solved, please contact us for help.
Q: Could ADL400 be used in IoT Energy Monitoring System for factory or building?
A: ADL400 has standard RS485 interface and MODBUS-RTU communication protocol which allow it to be integrate with our IoT Energy Monitor Solution that can enable our users to remotely check all the data collect by energy meters like ADL400 on their mobile phone or PC.

Q: What is Multi-rate/tariff function? How does it work?
A: First,multi-rate/tariff function was designed to be used for billing system. Second, the electricity price of different time duration in a day is different in some country.
Energy meter with this function can measure the kwh data and assign them to several time duration in a day and put a label of spike/peak/flat/valley kwh on them respectively. And if such energy meter was connected to the billing system by using a IoT gateway, it can send the kwh data of different time duration which was with the label of spike/peak/flat/valley kwh to the billing system for calculating the electricity bill of different time duration in a day.
For example, the electricity price of spike kwh is 5 USD/1 kwh, and time duration of from 9:00 am to 11:30 am was labeled as spike kwh.
Then, if energy meter record 3 kwh used in total during 9:00 am to 11:30 am, it will send the data of 3 kwh with the label of spike kwh to the billing system, and the system calculate the electricity cost of 3x5=15USD in total from 9:00 am to 11:30 am.
