| Functions and features | |||||||||||||||||
| Front board three fixed installation, up and down mounting holes center distance is 130-147 mm, users can choose any one by themselves. May select 6+1 digits display (999999.1kWh) or 5+2 digits display, it can be arbitrary set by users from far infrared or port of RS485 data communication. Standard configuration one port of pulse output passive (polarity), May select increase a distant port of pulse output passive (nonpolarity). And contact with all kind of AMR system conveniently, Complying with standard IEC 62053-31 and DIN 43864. There are a port of far infrared data communication and a port of RS485 data communication. Standard configuration communication agreement complying with standard DL/T645-1997, can also choose any other communication agreement. Three LED instructions power supply state, signal of energy impulse and communication state. Automatic detection the direction of the flow of load current. And instructions by individual LED. (Only yellow energy pulse signal when working, that is meaning the direction of the flow of load current reverse). Single direction single component measure single phase two wire active energy consumption. It is nothing with direction of the flow of load current. Complying with standard IEC 62053-21. Direct connect operation, there are two types wiring you may select. Standard configuration type 1A wiring, may select type 1B wiring (Product Configuration code is GF). Standard configuration extension terminals cover, in order to protect to use safety, may select short terminals cover. (Product Configuration code is BR). |
