Power 4-20 kVa
- Correction accuracy +/-1%
- Maintains overloads to 1000%
- Works with 10-fold starting currents
- System Bypass
- Works both from a network, and from the diesel - and the petrolgenerator
- Compliance to the state standard
- Multi-stage check in Quality Department
System of protection of loading:
Safety system:
Digital indication of parameters of a network:
Construction:
- shutdown of loading at accident of a network;
- shutdown of loading at tension deviation at the stabilizer exit out of limits, safe for loading, with the subsequent automatic inclusion at restoration of a network;
- protection of loading against the pulse retension caused by lightning discharges, transition processes in a network, the welding equipment, etc.;
- Lighting protection.
Safety system:
- shutdown of the stabilizer at an overload;
- shutdown of the stabilizer at short short circuit;
- control of temperature in the block; shutdown at an overheat;
- the analysis of parameters of a network and the test of system at start.
Digital indication of parameters of a network:
- indication of value of entrance and output tension;
- indication of current of loading;
- indication of input power;
- indication of a type of protective shutdown.
Construction:
- Voltage stabilizers of SNE-O represent floor blocks. Case elements are made of metal and painted by a wearproof polymeric covering. Color gray RAL 7035.
- Cases of all stabilizers from 4 to 20 kVA are unified. Dimensions (WхHхD): 295х510х330 mm. Models differ only in the power, range, weight and plugs of connection.
- The knot of electromecanics is built on the basis of the autotransformer of the German firm ThalhemTrafoWerke differing in high reliability and long service life. The autotransformer provides the high precision and smoothness of stabilization necessary for the exacting equipment.
- The card of control on the basis of the microprocessor provides control of parameters of a network of 3200 times a second, and instantly reacts to changes of entrance tension.
- The motor drive of Japanese brand of Mitsubisi provides high speed.
