    Product Profile

    The Apexto 1500 kVA (1.5 MVA) Three-Phase Pad-Mounted Transformer delivers reliable, continuous power for high-density compute infrastructure. Supporting up to ~1.2 MW of electrical throughput, it is the ideal capacity match for standard 20-foot hydro-cooled crypto mining containers and mission-critical data center facilities.

    Compatible with standard utility feeds like 13.8kV and 34.5kV, it steps down to dedicated 415Y/240V, 480Y/277V, or 600V outputs, with full custom voltage engineering available for any grid. Fully UL/cUL certified and DOE energy-efficient, it prevents thermal tripping under 24/7 full load, minimizes power losses, and guarantees hassle-free utility inspection approval on day one.

            FAQs

            How many amps does a 1500 kVA transformer provide at 480V?

            About 1,804A at full load on a three-phase 480V system.

            Is 1500 kVA enough for a 1.2 MW mining or data center load?

            Yes, in many cases. At 0.95 PF, 1.2 MW equals about 1,263 kVA, leaving useful capacity for operating margin and auxiliary loads.

            Can a 1500 kVA transformer feed a 2000A switchboard?
            Yes. A 1500 kVA, 480V transformer delivers about 1,804A, so a properly designed 2000A switchboard is a practical match.
            How much real power can a 1500 kVA transformer support?
            About 1,425 kW at 0.95 PF and up to 1,500 kW at unity power factor.
            What primary voltages can Apexto configure for a 1500 kVA transformer?

            Common options include 12.47kV, 13.2kV, 13.8kV, 24.94kV, and 34.5kV, with secondary voltage configured around the project.

            Should I choose loop feed or radial feed?

            Radial feed works well for a simple dedicated transformer. Loop feed is better for multi-transformer sites, future expansion, or more flexible medium-voltage distribution.

            Can Apexto build 13.8kV to 480Y/277V?

            Yes. 13.8kV to 480Y/277V is a common configuration for mining, data center, and industrial power distribution projects.

            Can a new 1500 kVA transformer fit my existing concrete pad?

            Often yes. Send us the existing nameplate, pad dimensions, cable-entry locations, and drawings so the enclosure layout can be checked before production.

            What information does Apexto need before quoting?

            Primary voltage, secondary voltage, total load, application, loop/radial feed, termination type, impedance/BIL requirements, and any existing utility or EPC specification.
