- The SPI1021 monitors voltage and frequency in plants for own generation of electricity. It fulfills the requirements of CEI 0-21 (Italy) and DEWA-standard (Dubai) Interface Protection (IP) according to DEWA Distributed Rrnewable Resources Generation programme (DRRG19, September 01, 2016).
- When the device has been installed, a self-test starts automatically. The self-test can be repeated when required. All values of the test are stored and can be read out at the display.
+ Monitoring of under- and overvoltage 0/15-520 V
+ Measuring of 3 phase with or without neutral or single phase
+ Monitoring of over- and underfrequency 45-65 Hz
+ Monitoring of quality of voltage (10-minutes-average)
+ Monitoring of vector-shift (connectible)
+ Input IN2 for selection of frequency window
+ Input In3 for selection of mode transitory or definitive
+ Input Y0/Y1 for monitoring function of connected switch (automatic detection of nc/no)
+ Relay K2 picks up (on time <500ms) only at failure at switch connected to K1
+ 2 restarts at switch-on error of connected switch
+ Selftest with storing of values
+ Switching delays adjustable 0,05…130 s
+ Switching-back-delays adjustable 0…999 s
+ Different switching time according to type of alarm and selected mode
+ Switch-on delay 300 s
+ All parameters preset according to CEI 0-21
+ Alarm counter for 100 alarms with value, reason and elapsed time
+ Recording of added time of alarms
+ Input for standby (off time <50ms) with counter and recording of time
+ Simulation for testing
+ Sealing, all parameters can be read out while sealed
+ Easy installation and programming with 6 preset programs
+ Supply-voltage AC/DC 24-270 V
+ Housing for DIN-rail-mount, 105 mm wide, mounting height 70 mm
