The power supply of an automatic gate is a crucial aspect for its optimal and secure operation. Choosing the appropriate intensity is essential to avoid overloads and guarantee the longevity of the system. This article addresses the different aspects to consider to determine the minimum intensity required for an electric gate, taking into account the choice of motor, the necessary voltage as well as the normative precautions to follow.
Choice of motor and impact on electrical intensity
The choice of motor is essential in determining the electrical intensity required. Low energy consumption motors are generally favored to minimize the impact on the domestic electricity network. However, it is crucial to know the motor power expressed in watts (W), because it directly influences the intensity (amps, A) requested. Indeed, a more powerful motor will require higher current. It is recommended to evaluate the technical specifications of the selected motor to determine the electrical load it will introduce into the system.
Compliance with electrical standards and choice of circuit breaker
Standard C 15-100 regulates the electrical installation of automatic gates in France. This standard prescribes that the circuit powering the gate must include a 30 mA differential circuit breaker rated at 16A to protect against short circuits and overcurrents. This choice of circuit breaker helps prevent electrical risks and ensure the proper functioning of the gate. It is therefore essential to ensure that any installation complies with these regulations to avoid any electrical problems and guarantee safety.
Gate voltage and power supply methods
Electric gates can operate on different voltages, the most common being 24 V for low voltage and 230 V for domestic voltages. The operating voltage chosen will also affect the choice of intensity. For example, a 24 V system will typically consume fewer amps than a 230 V system for the same motor power. It is therefore important to consider the type of power supply (solar or grid) and whether a converter or adapter is required to adjust the output voltage.
Installation requirements and practical recommendations
It is recommended to provide a dedicated electrical line from the main panel to power the gate. The use of a U1000 R2V type cable is often recommended to ensure the safety and performance of the installation. If low voltage motors are used (12 or 24 V), the lines can be longer without significant loss, provided that the minimum cable section is respected to avoid any voltage drop.
Impact of electricity consumption on intensity
The total electrical consumption of an automated gate, including the motor and accessories (lighting, intercom, etc.), must be taken into account. A preliminary estimate of this consumption will make it possible to determine whether the available intensity is sufficient or whether adjustments to the electrical panel are necessary. Manufacturers often provide indications on the average consumption of systems to guide users in their choice.
