Brief introduction
DTSY999 single phase is new age intelligent instrument, combination advanced integrated solid technology and SMT crafts. The performance accords with International Standards IEC1036 They feature advanced principle, simple construction, high accuracy and sensitivity, long service life, strong overload and anti-power theft, alarming of remainder, storing data over 20 years, setting secret, etc.
Main Function
1. Pre-alarming: when the remainder is less than alarming limit, first the out relay will cut off load, when IC card is set inside the meter, which can re-work and the LED always lights to remind the user to purchase power timely, and the meter will cut off till remainder is over.
2. Load control: when the load is beyond the setting value, the relay inside the meter will cut off load automatically to remind the user. In this case, meter can re-work by reducing load and re-insetting the card
3. Self-checking breakdown: a meter can self-check IC card, LED display, relay, etc.
