UPS Leoton (OFF-Line) NOVA 2000

Products "Leoton» NOVA 2000 sets the system load protection against over-voltage in the network

Features Protection Module Surge:

* Protection module from exceeding the supply voltage (hereinafter - MZPSN. ) for disconnection from the power consumers with increasing voltage over the set values ​​(adjusted to 220 + 10%, i.e. 252 B).
* MZPSN provides off no later than 5 ms after exceeding the threshold. Threshold - 220 + 10 = 252% The
* Activation MZPSN provided in excess of any voltage half-waves
* Inclusion consumer grid is provided 2 minutes after the voltage decrease below the trip threshold
.. * the time delay is non-volatile, ie, off state is stored in MZPSN even when blackout, and de-energisation continues the countdown to turn

Unlike analogue (dignity):.

* fast response time (<3 ms plus the relay response time - 5..10 ms)
* reaction to the excess voltage at both half-waves (exclude the possibility of damage in the network equipment power surge of the same polarity)
* no initial delay inclusion:
* testing of the trip delay, even after the disappearance of the network (memory)
* protivoiskrovaya chain to protect the relay contacts from sticking arc when controlling inductive loads (motors, Transformer Ora).
