| Functions and features |
It support repeat recharge and one-time recharge from IC programmer and PC machinery online at the same time. OR it can individual offline recharge. (Please specified when ordering).
The IC card use logic and encryption, with code and data against false
Standard configuration payment by kWh, may select payment by money. (Please specified when ordering).
Standard configuration of the prepayment management system use of single version, may select network version. (Please specified when ordering).
It has load control and function of automatic fault detection and instructions, standard configuration without function of open terminals cover and detection, may select open terminals cover and cut power. (Please specified when ordering).
Standard configuration 7 LCD digits display, 6+1 digits display (999999.1kWh), may select 5+1LED digits display. (Product Configuration code is PF).
A port of pulse output passive closed (polarity), complying with standard IEC 62053-31 and standard DIN 43864.
Three LED instructions power supply state (green), signal of energy impulse (red) and direction of the flow of load current (yellow).
Automatic detection the direction of the flow of load current. When the yellow LED display, 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 QE).
Front board three fixed installation, standard configuration extension terminals cover, in order to protect to use safety, may select short terminals cover. (Product Configuration code is QH). |
