30-Second Fit Check

Need a high-power DC source? All models deliver 30 kW with voltage ranges from 0-60 V up to 0-1000 V and currents up to 1000 A.
Four regulation modes: Constant Voltage (CV), Constant Current (CC), Constant Power (CP), Constant Resistance (CR) with adjustable internal resistance simulation.
Comprehensive protection: Overvoltage (OVP), Overcurrent (OCP), Overpower (OPP), Overtemperature (OT), and Safety OVP (60 V model only).
Built-in color TFT touchscreen HMI with two rotary knobs; optional water cooling for reduced audible noise and cooler exhaust.
Remote control via galvanically isolated analog (0-5/10 V), USB, Ethernet (SCPI/ModBus RTU), and optional industrial interfaces (CAN, Profibus, EtherCAT).

What It Is + Why It Matters

High-performance 30 kW programmable DC power supply series designed for industrial test systems, laboratory experiments, and automated production lines.
An integrated function generator (sine, triangle, square, trapezoid, ramp, DIN 40839, arbitrary) allows dynamic load profiling without external waveform generators.
Specialized PV (solar) simulation according to EN 50530 and fuel cell simulation enable inverter testing and renewable energy research.
True master-slave parallel operation supports up to 64 units for a total of 1920 kW, with automatic current sharing via the Share bus.

Note: The 60 V model incorporates reinforced insulation and a Safety OVP alarm that triggers at 60.6 V to maintain SELV compliance. Always use remote sensing to compensate for cable voltage drop (max. 5% U_Nom).

Key Specs

Integration & Installation

DC output via copper blade terminals with M10 (up to 200 V) or M6 (≥360 V) bolts; use ring lugs or copper bars for low inductance.
AC input via a 5-pole plug (3x L + PE, N optional); included strain relief and grounding point for additional PE connection.
USB stick slot (front) for data logging, profile save/load, and arbitrary waveform upload (FAT32, max 32 GB).
Voltage controller speed selectable (Slow/Normal/Fast) to minimize overshoot; SEMI F47 ride-through available (firmware KE 3.02+).

Best for / Not for

Best for: High-power battery charge/discharge testing, solar inverter MPPT validation, industrial DC motor testing, semiconductor burn-in, and large-scale laboratory DC power needs.
Not for: Direct connection to generators or UPS (must run on grid); series connection of models with DC+ potential exceeding 2000 V (e.g., 1000 V model); use without proper DC terminal cover when voltage presents a hazard.

Selection Checklist + RFQ

Choose model based on required voltage (60 V … 1000 V) and current (80 A … 1000 A) ratings.
Confirm AC supply: 400 V or 208 V (derated power 18 kW).
Select cooling: standard air cooling or optional water cooling (lower noise, no waste heat into room).
Specify needed interfaces (analog, Ethernet, USB) and optional fieldbus module (CAN, Profibus, EtherCAT, etc.).
Plan for rack depth and clearance (≥30 cm rear for air cooling) and DC cable cross-section per rated current.
