In AI workloads, instantaneous power surges demand uncompromised reliability, as any brief drop in power can undermine GPU computation. To address this demand, Chroma developed the 62450D-2000HL, a bidirectional DC power supply and regenerative electronic load purpose-engineered for high-voltage, high-power testing.
With the discontinuation of NH Research (NHR) 9300 systems, many labs are seeking a replacement that delivers higher flexibility, better performance, and modern integration. Chroma’s 62000D regenerative DC power systems offer a clear upgrade—combining compact modular design, advanced control, and industry certifications that ensure long-term dependability.
Chroma’s 62450D-2000HL Bidirectional DC Power Supply is designed with high power density, delivering up to 45kW output in a compact 4U chassis. With master-slave parallel configuration, it can deliver up to 360kW in a standard 41U 19-inch rack, and scale even further to MW-level output through cross-cabinet parallel connection.
Chroma’s Ultra-High Stability DC Power Supply is engineered for the stringent demands of synchrotron accelerators, delivering ultra-low ripple, high accuracy, and fast transient response to ensure beam stability and system integrity.
Chroma releases a high density 45kW Bidirectional DC Power Supply that can toggle between two output ranges to meet the evolving needs of various industries from electric vehicles to renewable
In an industry-first, the 62450D-2000HL enables one-key switching between two output ranges within a single unit, effectively providing the output range of two units in one. Users can easily switch between the high voltage (2000V/±60A/±45kW) and high current (650V/±180A/±45kW) range with a single touch, offering up to 8x wider output range capabilities to meet the testing needs of a diverse array of devices under test (DUT).
In the electric vehicle (EV) sector, our upgraded models now support charging current testing needs for 11kW bidirectional onboard charger (BOBC) systems, accommodating both 400V and 800V high-voltage platforms.
Chroma 62180D-1200 Bidirectional DC Power Supplies support paralleling up to 30 units for an output power of 540kW and an output current of 1200A. This meets the requirements of today’s fuel cell engine assemblies, enabling the instruments to function as a highly efficient fuel cell simulator with energy recycling functionality.
62000D models offer power ratings of 6kW, 12kW, 18kW, 36kW, and 45kW with parallel and series operation capabilities and voltage ranges spanning from 0 to 100V/600V/1200V/1800V. With its four times auto-ranging operation range, the 62000D can cover a wide range of low voltage/high current and high voltage/low current scenarios for devices under test. This consolidation of multiple DC power supplies into a single 62000D unit brings space and cost savings when integrated into standard ATE systems or laboratories.
Chroma ATE launches the 62000E series of 1U DC power supplies with 3-channel output. This brand new addition to Chroma’s line of power supplies adopts full digital circuit control and
