For a non-isolated high-voltage output power supply, the output voltage can be 200V, 400V, 600V, 1000V, 1250V, 1500V, 2000V, 3000V, 5000V, -200V, -600V, -1250V, -1500V, -2000V,-3000V, etc. It should be confirmed that if the output voltage is adjustable and if the current and voltage are constant. Learn about specifications, safety requirements, and selection criteria. Based on a flexible architecture, 400V HVDC power can be implemented at a wide variety of telecom and data centers sites. Mouser offers inventory, pricing, & datasheets for 400 V Power Supplies. These power supplies are stabilized, short-circuit proof and can be set to 400 V DC output.
