The Japanese manufacturer Diamond enjoys an excellent reputation not only for antennas and lightning protection systems, but also for power supplies. The range of products extends from the typical 30A power supply with transformer to various light switching power supplies with up to 60A. Diamond always pays attention to a reasonable selection of the type and number of connections. This way it is easy to quickly connect several loads to the power supply. The devices usually have an analog instrument that can be switched to either voltage or current.
