This compact 40 ampere modular power supply from the Sitop series is only 150mm wide. Its 20 ampere equivalent is only 70mm in width. Despite their small dimensions these standard rail power supplies for connection to 3-phase 400-500VAC networks, have a range input from 320 to 575VAC. They supply a reliable 24 volt supply even when there are large deviations in the voltage supply. The power unit from the 40 ampere power supply, now supplies 60 amperes for five seconds, so it can switch on terminal equipment with high starting currents. Its efficiency up to 93% reduces energy consumption and heat build-up in the control cabinet. These power supplies have rugged metal enclosures. They can provide three times the rated current to meet short-term peak power demands. The short-circuit response can be set with the options: latching shutdown or constant current with automatic reamp.
