30-Second Fit Check

Need to test multiple components in a single rack unit? Three independent, galvanically isolated channels in a 3U enclosure.
Each channel delivers 0-60V to 0-920V and 0-20A to 0-170A with 5kW autoranging power (15kW total device power).
Seamless two-quadrant source-sink operation per channel; regenerative energy recovery up to 96%.
High-speed control interfaces: EtherCAT, CAN FD, 1 Gbit Ethernet, USB; built-in function generator with PV/FC simulation.
Protection suite per channel: OVP, OCP, OPP, OT; parallel operation for up to 8 units (120kW) via Master-Aux bus and Share bus.

What It Is + Why It Matters

Industry's most compact 3-channel bidirectional DC power supply in 3U format, replacing three single-channel devices and saving over 50% rack space.
Three independent, fully isolated channels enable parallel testing of motors, inverters, and on-board chargers within the same test setup – accelerating development cycles in fast-moving industries.
Each channel is a complete two-quadrant device with autoranging output and regenerative energy recovery up to 96%, significantly reducing both operational and HVAC energy costs.
Integrated function generator with PV (EN 50530) and fuel cell simulation, plus arbitrary waveform generation for complex test sequences.
Built-in EtherCAT (1 ms cycle time), CAN FD, and 1 Gbit Ethernet ensure ultra-fast system integration and data acquisition for demanding automated test environments.

Note: All three channels are galvanically isolated from each other and from the AC input. The 208V AC version (optional) operates without power derating. In sink mode, energy is recovered to the grid; consult local utility regulations.

Must be installed in a closed 19" rack/cabinet with lockable doors; ensure adequate ventilation and grid compliance for energy recovery.

Best for / Not for

Best for: Multi-component automotive testing (motors, inverters, OBCs simultaneously), battery module/pack simulation, high-density automated test racks, renewable energy inverter validation, and any application requiring three independent, isolated bidirectional DC channels in minimal rack space.
Not for: Applications requiring a single channel with more than 5kW, series connection of channels (not supported), or environments without three-phase AC supply and proper rack cooling.

Selection Checklist + RFQ

Choose voltage/current rating matching your test requirements per channel (60V, 80V, 200V, 360V, 500V, or 920V).
Verify per-channel power demand ≤ 5kW (autoranging); total device power = 15kW across all three channels.
Confirm three-phase AC supply availability (208-480V AC); specify standard or 208V US version.
Select control interface: built-in EtherCAT, CAN FD, Ethernet, USB, plus Digital I/O.
For multi-unit parallel systems, specify total channels and total system power (up to 8 units / 120kW); all channels must share the same voltage rating.
Plan for energy recovery grid compliance and possible grid protection device installation.
