EA-PUB 11500-120 6U WC 60kW Bidirectional Programmable DC Power Supply with Regenerative Load

The EA-PUB 11500-120 6U WC is a high-power, water-cooled, bidirectional DC power supply and programmable DC power unit, also functioning as a regenerative DC load and energy recovery system. This versatile TPS programmable power supply offers both source and sink capabilities, making it an ideal two-quadrant DC source for demanding test applications such as battery pack cycling, power converter testing, and photovoltaic inverter evaluation. It delivers a wide output range up to 1500V DC power supply and 120A DC power supply, with a powerful 60kW constant power profile. With an exceptional 96.5% efficiency bidirectional power supply design, it minimizes energy consumption and heat dissipation. It operates from a standard 380-480V 3-phase AC input with active PFC 0.99 power factor to reduce grid impact. The unit features IP20 ingress protection and is designed for a 0-50°C operating temperature range. The integrated water-cooled DC power supply (WC) system ensures reliable, quiet operation at full power in high-density rack installations, making it a robust solution for high-power laboratory and production test environments.
