30-Second Fit Check

Need a scalable, high-power DC source 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 output; efficiency up to 96.5%.
Designed as a power unit for master-slave systems; a single master can control multiple PU 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 programmable 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 PSI 10000 or PSB 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.
Multiple units can be combined via the built-in master-slave bus and Share bus to form a single, high-power source system of up to 1920kW, with the master handling all setpoints and measurements.
Equipped with analog (0-5/10V), USB, and Ethernet interfaces plus an optional plug-in slot for industrial protocols (CAN, Profibus, EtherCAT, etc.), ensuring seamless integration into automated environments.
An optional function generator (sine, square, ramp, arbitrary, PV/FC simulation) and optional water cooling further expand the capabilities for dynamic testing and high-density installations.

Note: The PU 10000 series is a unidirectional power source only; it cannot sink current. Ensure a compatible master unit with TFT display is available if full local control and monitoring is required.

Key Specs

AC input: 208-480V AC, 3-phase, active PFC, 45-65Hz; automatic derating to 18kW at 208V AC.

DC output power: 30kW autoranging; output efficiency up to 96.5% (model dependent).
Control panel: LED status indicators (Power, Remote, Error, On, Off) and DC on/off pushbutton; no TFT display.
Interfaces: 15-pin analog (0-5/10V), USB-B (rear), USB-A (front), Ethernet; optional slot for IF-AB digital modules (CAN, Profibus, etc.).
Master-slave bus (RS485 via RJ45) + Share bus (BNC) for up to 64 units (1920kW total).
Dimensions (WxHxD): 19" x 4U x 668mm; Weight: approx. 50 kg (air-cooled), 56 kg (water-cooled).

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.

Best for / Not for

Best for: Building large-scale, cost-efficient master-slave DC source systems (e.g., industrial DC bus supply, battery charging, electrolysis, motor testing) where the master provides the interface and the PU units supply raw source power.
Not for: Applications requiring a standalone unit with an integrated TFT display and full local controls; sink/load operation (this is a unidirectional source only); or operation without a compatible master unit for full functionality.

Selection Checklist + RFQ

Choose voltage/current model matching your load requirements (60V, 80V, 200V, 360V, 500V, 750V, 920V, 1000V, 1500V, or 2000V).
Confirm total source 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 circuit protection.
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 PU units plus one compatible master unit (e.g., PSI 10000 4U or PSB 10000 4U series) to complete the system.
If optional function generator or digital interfaces (Profibus, EtherCAT, etc.) are needed, specify the corresponding options/modules.
