Chroma has launched a series of 3U AC power supplies for regenerative grid simulation with power ratings up to 15kVA.
Chroma 61809/61812/61815 models are four quadrant, fully regenerative AC Power Sources at 3U height with power ratings of 9kVA/12kVA/15kVA respectively. The 3U height form factor occupies less space and provides flexibility for users when configuring their system cabinet or test bench depending on their application, from grid simulation to a wide range of other power test applications.
The models support single phase and 3-phase output, 350 VLN wide output voltage range, 100 percent DC output, 200V~480V universal voltage input, and are completely regenerative which can save operational cost.
Users can also extend the output power by connecting up to three units in parallel, achieving a high power density configuration of 45kVA output power at only 9U height. Besides grid simulation for server power or electrical commercial products, the 61800 models can be applied to applications in green energy products including PV inverters, energy storage systems (ESS), power conditioning systems (PCS), micro grids, power hardware-in-the-loop (PHIL), electric vehicle power supply equipment (EVSE), on-board charger (OBC) and bidirectional on-board charger (BOBC).
The Chroma 61809/61812/61815 models are equipped with an intelligent touch screen providing users with an intuitive UI to quickly perform multiple settings and operations. Input from the touch screen and rotary knob make it easy to program and observe the input settings. The PLD advanced programming functions are greatly optimized, such as additional tap and swipe operations when programming in the LIST Mode as well as copying and pasting functions when setting sequences, giving users a more intuitive and convenient way of programming similar to operating a smartphone.
