30-Second Fit Check

Need a scalable, high-power bidirectional source/sink without the cost of an integrated display? Models cover 60V to 2000V, with currents up to 1000A.
DC power: 30kW per unit (derated to 18kW at 208V AC) with fully autoranging and regenerative energy recovery up to 96.5%.
Designed as a power unit for master-slave systems; a single master (with display) can control multiple PUB units, reducing total system cost.
Status indication via LEDs; no TFT display – configuration and setpoints are managed by the master or via remote control.
Comprehensive protection: OVP, OCP, OPP, OT, MSP, SF; master-slave bus and Share bus for parallel connection of up to 64 units.

What It Is + Why It Matters

Cost-optimized bidirectional DC power unit in 4U 19" rack format, specifically designed as an auxiliary (slave) unit to extend the power of a master device (e.g., from the PSB 10000 or PSBE 10000 series).
The autoranging output stage allows maximum current at lower voltages or maximum voltage at lower currents, covering a wide range of test scenarios with a single model.
Energy consumed in sink mode is regenerated to the grid with up to 96.5% efficiency, significantly reducing cooling costs and electrical consumption compared to passive loads.
Multiple units can be combined via the built-in master-slave bus and Share bus to form a single, high-power system of up to 1920kW, with the master handling all setpoints and measurements.
For standalone or backup use, the device can be configured via the front USB port and a simple SCPI/ModBus command set; an optional function generator is available for dynamic testing.

Note: The PUB 10000 series does not include a TFT display; instead, it uses an LED status panel. In sink mode, ensure compliance with local grid regulations for energy feedback.

Integration & Installation

DC output via copper busbars (M10 or M6 bolts) on the rear panel; plastic covers and strain relief accessories included.
Three-phase AC mains via 5-pole connector (L1, L2, L3, N, PE); fixed connection required with external circuit breaker/contactor.
Master-slave bus connection via standard CAT5 patch cables; Share bus via BNC coaxial cables (50Ω).
Optional water cooling available for reduced ambient noise and better heat management in high-density cabinets.
Must be installed in a closed 19" rack/cabinet with lockable doors; ensure adequate ventilation or water supply for cooling, and consult grid regulations for energy recovery.

Best for / Not for

Best for: Building large-scale, cost-efficient master-slave systems (e.g., battery pack cycling, power supply burn-in, fuel cell testing, solar array simulation) where the master provides the interface and the PUB units supply raw bidirectional power.
Not for: Applications requiring a standalone unit with an integrated TFT display and full local controls; series connection of DC terminals (not supported); or operation without a compatible master unit for full functionality.

Selection Checklist + RFQ

Choose voltage/current model matching your test requirements (60V, 80V, 200V, 360V, 500V, 750V, 920V, 1000V, 1500V, or 2000V).
Confirm total sinking/sourcing power requirement ≤ 30kW per unit; note derating to 18kW at 208V AC input.
Verify three-phase AC supply (208-480V) and plan for external switching and grid compliance for energy recovery.
Select cooling option: standard forced air or optional water cooling (for reduced noise and heat emission).
For multi-unit systems, order the appropriate number of PUB units plus one compatible master unit (e.g., PSB 10000 4U or PSBE 10000 4U series) to complete the system.
If optional function generator or digital interfaces (Profibus, EtherCAT, etc.) are needed, specify the corresponding options/modules.
