FAQ
Q: Do your company also have paired CTs for APM meters?
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 AMC meters (current input via CTs)
Q: How can I set the CT or PT ratio of APM meters?
A: Current ratio of APM meters could be set by using the keypads on APM meters and following the instruction of APM meters manual. Also, setting need to be according to the CTs or PTs ratio which were paired with APM meters. For example, if the current input is via 250A/5A CTs, the CT ratio on APM meters should be set to 250/5=50. And if the voltage input is via direct connect, PT ratio on APM meters should be set to 1. When the problem hasn’t been solved, please contact us for help.
Q: Could APM series of meters be used in IoT Energy Monitoring System for factory or building?
A: Yes, APM series of meters have 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 APM meters on their mobile phone or PC. For more information, please Contact us or check in IoT Energy Monitoring Solution Introduction.
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.Other Question?
