Block Emergency start Reserve "BAVR"

The BAVR unit is recommended to be installed in the immediate vicinity of the reserved UKZ. The inputs and outputs of the unit must be grounded with a lightning protection system.

Technical characteristics of the emergency start-up unit of the BAVR reserve:

- Two UKZ (main and backup) of any type with output parameters can be connected to the unit:

- output voltage range - from 2 to 100 V;
- maximum output current - 90 A;
- maximum power - no more than 9 kW.

- Through the block, power is supplied to the main and backup UKZ from an industrial two-phase network of 230 V.
- The unit commutes the output current of a working (operational) UKZ to the load
- The unit automatically switches the main UKZ to the backup in case of failure of the main UKZ (output voltage - less than 2 V)
- The unit disconnects the UKZ from the 230 V industrial network when the supply voltage goes beyond (160-260) V and, if it is in good condition, switches it to the second network
- Switching the UKZ from the primary to the backup and switching the network phases is carried out according to the formula “any healthy UKZ is automatically connected to any healthy phase of the network with priority - the main UKZ and the first phase of the network”. The voltage from the faulty UKZ is removed. In the event of a failure of the network phases or both of the UKZ, a restart of the unit is possible only in manual mode by switching the power-on circuit breaker after fixing the network fault or replacing the UKZ
- The voltage supply to the main UKZ takes place with a delay of 4 seconds, the main UKZ switches to backup - with a delay of 12 seconds, from the backup to the main UKZ - 6 sec
- All parameters of the unit (range of output voltages, minimum value of output voltage UKZ, switching delay times, etc.) are set programmatically and can be changed in each specific case of unit operating conditions
- The unit can withstand a voltage increase of up to 300 V
- The unit switches the reference electrode from the main UKZ to the backup one and vice versa, depending on which UKZ is currently on
- The unit carries out the output of auxiliary power at 230 V and a maximum power of 100 W from any of the properly functioning phases of the network
- Maximum power dissipation - no more than 15 W
- The mass of the block - no more than 8 kg
- Placement of the unit - rooms with uncontrolled climatic conditions, where temperature and humidity fluctuations do not significantly differ from outdoor vibrations, without direct exposure to solar radiation, precipitation, wind, sand and dust
- Ambient temperature - from minus 45 ° С to +50 ° С
- Relative humidity - up to 95% at a temperature of +25 ° С

- Dimensions - 390x332x100 mm
