Cannabis – The miracle plant
Even in ancient times, Cannabis sativa (as the plant is known in Latin) was used as a medicinal plant. The two key active ingredients it contains are tetrahydrocannabinol (THC) and cannabidiol (CBD), which can be used to treat chronic pain, muscle spasms, and can improve a person’s mood. Cannabis offers benefits that other active ingredients cannot. Cannabis is not just an illegal narcotic, it is also a component of effective medicines that are being approved as prescription drugs in an increasing number of states and countries.
The cultivation of the plant for medical purposes is done in indoor grow rooms with special lighting. Growers have been moving to modern warm-tone LED lamps. With this type of lighting, the capacitive switching power supplies require no ballast and can reach currents of up to 100 times of the operation current once activated, which would result in the melting (or fusing) of the relay contacts after only a few switching cycles. These aspects must be considered when selecting appropriate switching components when planning new systems or modifying existing systems.
Comatreleco’s CHI series of high-inrush relays are made specifically for use in these lighting applications and will ensure operational safety, with several switching cycles per day. Due to the integrated zero-voltage switching and the additional tungsten prerun contacts, inrush currents of up to 800A and operating currents of 16A can be managed reliably.
- The devices are available in one- and three-phase designs
- Multi-phase devices are especially well suited for clustered control of various lighting groups.
- Switching of capacitive consumers with the CHI14 – Inrush current of approx. 3.5 A per ballast
