Light stabilizer-dimmer ESDONI EN series

The ESDONI-EN high-performance dimmer-stabilisers can attain performance figures above 99% at full load. These figures are possible because of the use of power relays in the switching. The power autotransformer, with its 14 outputs directly provides the power required for operation (output, installation). Compared to semiconductors, the use of relays provides greater reliability in out-of-control actions and a high level of insulation between the ac mains and the electronic control circuits. Moreover, they also guarantee several hundreds of thousands of operations, resulting in dimmer-stabiliser equipment high operational reliability and long life. Each of the independent phases is overload protected by a magnetic-thermal breaker at the mains input, together with a thermal switch to protect against excessive interior temperature. In order to prevent the lighting installation from shutting down, it is necessary for static equipment to incorporate a bypass system with automatic reset that would operate under the following circumstances: * Control board problems. * Low output voltages. * Excessive equipment temperature.
