Construction

1. Unique design: The use of surface-mounted components reduces the overall dimensions of the control panel.

2. Plastic housing: Provides protection against damage such as collisions, careless opening, dust ingress, as well as contact with the external environment, providing additional durability and safety of the device.

3. Varistor: The inclusion of a varistor in the design protects the control system from sudden voltage surges in the electrical network, ensuring stable and safe operation of the control unit.

4. Built-in fuse: Provides additional protection for the internal relays of the control unit in the event of a short circuit at the outputs, such as valves, ignition transformer, motor and lock signal.

These security measures contribute to:

– Reliable and long-term operation of the control system.

– Stability in various operating conditions.
