CD15-040B — ActionPower Programmable Bidirectional DC Power Supply

The ActionPower CORTEX DC Series (Bidirectional) is a high-performance programmable bidirectional DC power supply combining DC source and regenerative electronic load functionality in a single 3U rack module. Operating from 0V to 2000Vdc at 15kW to 30kW per module, it scales to 3MW via parallel connection. Built on a unique topology, it achieves an ultra-fast response time of less than 500μs and voltage/current accuracy of 0.02% F.S.

As a bidirectional supply, the CORTEX DC Series can seamlessly switch between acting as a DC power source and a regenerative electronic load — absorbing energy from the DUT and feeding it back to the grid. The automatic 'source' and 'load' switching is smooth and ultra-fast with no overshoot or delay in state transitions. The auto-ranging function maintains rated output power over a wide voltage-current envelope.

Battery simulation supports LiMn2O4, LiCoO2, LiFePO4, NiMH, ternary lithium, LiTiO2 and PbO2 chemistries. PV simulation includes static curves, curve programming, static and dynamic MPPT, weather simulation and photovoltaic panel shading. Operation modes include CC, CV, CP and CR. Dynamic mode and programmable sequence modes are also available.

Scalability uses the DMPS (Digital Matrix Parallel System) with high-speed fibre optic communication between up to 100 units. Module redundancy automatically bypasses faulted slave units to maintain continuous operation. Cabinet configurations up to 42U with 19-inch rack are supported.

Interfaces include Type-B USB, Ethernet, CAN, RS232, RS485 and ModBus TCP. The front panel features an 8-inch FHD touch screen.
