Power supply for automation devices in the WAGO range contains a large number of power supplies that can supply a voltage of 5 to 48V DC up to 40A. There are both single-phase and two-phase sources with wide input voltages, and are capable of working from a source of constant voltage. Most sources support the Top Boost feature, which allows the power source to maintain a high output current of 25ms to trigger the automatic switch at the output, and a number of sources also have Power Boost function, which allows the power to boost up to 4s at multiple outputs over nominal, higher voltages up to 4s. Most power supplies can be connected in parallel and gain more power.
