30-Second Fit Check

Need a high-current DC load for your test rack? Models cover 80V to 750V, sinking current up to 510A.
Power ratings range from 1200W to 7200W peak; steady-state power from 1200W to 4500W depending on model and ambient temperature.
Four regulation modes: Constant Voltage (CV), Constant Current (CC), Constant Power (CP), Constant Resistance (CR).
Built-in 4.3" TFT touch panel with two rotary knobs for intuitive manual setpoint adjustment.
Comprehensive protection suite: OVP, OCP, OPP, OT, PF; master-slave parallel connection for up to 16 units.

What It Is + Why It Matters

High-performance 3U 19" rack DC electronic loads designed for demanding test systems and industrial applications.
An integrated function generator (sine, triangle, square, trapezoid, ramp, DIN 40839, arbitrary, XY table) enables dynamic stress testing without extra equipment.
Specialized battery test mode with Ah/Wh/time counters and dedicated MPPT tracking for solar panel and inverter validation.
Flexible remote control: built-in analog interface (0-5/10V), USB, plus optional plug-in modules for CAN, CANopen, Profibus, ProfiNet, RS232, Ethernet, ModBus TCP, EtherCAT.
True master-slave parallel operation with active current sharing via Share bus, enabling up to 115kW total system power.

Note: The device is air-cooled with temperature-dependent derating; ensure adequate ventilation (min. 30cm rear clearance) and consider peak vs. steady-state power at your operating ambient temperature.

Key Specs

DC input voltage: 80V to 750V (model dependent); Current: 20A to 510A.
Power classes: 2400W / 4800W / 7200W peak; steady power derates with temperature (see datasheet).
AC supply: 90-264V AC, 45-65Hz; Consumption: max. 45W to 130W depending on power class.
Display: 4.3" colour TFT touchscreen (480pt x 272pt) with two rotary knobs.
Interfaces: 15-pin isolated analog (0-5/10V), USB-B (rear), USB-A (front), master-slave bus (RJ45), Share bus, slot for optional digital modules.
Remote sensing compensation: max. 5% UNom; voltage controller speed selectable (Slow/Fast).
Dimensions (WxHxD): 483 x 133 x 568mm (19" x 3U x 22.4"); Weight: 9-17 kg (model dependent).

Integration & Installation

DC input on rear panel with copper bus bars; plastic cover included for contact protection; suitable for ring lugs (M8 or M6 bolts depending on voltage class).
AC supply via standard IEC wall socket (mains cord included); AC consumption is low, so no special fusing usually required (recommend type C or K circuit breaker with 16 A rating).
Master-slave connection via standard CAT5 patch cables (RJ45 bus); DIP switches for bus termination; Share bus via supplied 2-pin plug for current balancing.
Optional interface modules are user-installable in the rear slot; ESD precautions apply.
Must be installed in a 19" rack/cabinet with adequate ventilation; ensure minimum 30cm rear clearance.

Best for / Not for

Best for: High-power DC source testing, battery discharge characterization, solar panel MPP profiling, automotive 12V/24V/48V system validation, fuel cell testing, power supply burn-in testing, and large-scale industrial test systems requiring scalable parallel loading.
Not for: AC load applications, series connection of DC inputs (not permitted), regenerative energy recovery (this series is conventional, air-cooled), or environments without adequate rack cooling.

Selection Checklist + RFQ

Choose voltage/current model matching your source specifications (80V, 200V, 360V, 500V, or 750V).
Verify peak and steady-state power requirements at your operating ambient temperature, accounting for temperature-dependent derating.
Confirm available AC mains (standard wall socket) and plan for external DC circuit protection if sources are not current-limited (e.g., batteries).
Select required interfaces: built-in analog/USB plus optional digital modules (Ethernet, CAN, Profibus, etc.).
For master-slave operation, specify total system power and number of units (max. 16); ensure all units are the same model.
