| Functions and features | |||||||||||||||
| Front board three fixed installation. 5+1 digits display (99999.1kWh) by step motor type impulse register. 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. Standard configuration only one LED instructions signal of energy impulse (red), may select add instructions power supply state (green) and automatic detection the direction of the flow of load current and instructions by LED (when display yellow, that is meaning the direction of the flow of load current reverse). Please specified when ordering. Single direction single component measure single phase three wire active energy consumption. It is nothing with direction of the flow of load current. Complying with standard IEC 62053-21. Direct connect operation, type 2A wiring. Standard configuration extension terminals cover, in order to protect to use safety, may select short terminals cover. (Product Configuration code is TK). |
