Features:
- Energy measurement function:
- Three phase power supply, one phase or two phases power failure, the precision of measuring is not affected.
- Active and reactive energy measures separately.
- Optocoupler isolation with active and no power pulse output interface
- Loss of phase indicates function:
- DTSX227, DSSX227 electronic active and reactive integration energy meter use three luminotrons to indicate if it is lack of phase. Three luminotrons separately instead of ABC phase. If one of phase was lack, the relevant indicator will put out.
- Communication function: Infrared and RS485 communication
- Current reversal
- Earth load
- Advanced anti- fraud of IC card port attack,
- IC card contacts shorten by metal sheet
- Electrical spark (like motor starter)/ ESD attack on IC card contacts;
- AC/DC or high frequency signal injection on IC card contacts;
- 400Vac attack on IC card contacts
- Pre-alarm when out of credit, LCD flash display, Beeping (optional)
- High-reliable magnetic latching relay, ON/OFF 5000 times with Imax current;
- Cut-off user supply for overload protection, resume after 5 minutes (programmable)
- Highly security transaction upon encrypted data & password mechanism
