Description

30-Second Fit Check

Need a medium‑voltage DC load for power supply testing? Input is 0–200 V, rated 0–36 A.
Rated power: 1000 W peak, 900 W steady (autoranging U/I/P).
Operates in CV, CC, CP, CR modes with automatic crossover.
AC supply: 90–264 VAC, 45–65 Hz; consumption max. 40 W, fuse T 2 A.
Protection: configurable OVP (0–206 V), OCP (0–39.6 A), OPP (0–1100 W), plus OT and PF.
Dimensions: 276 × 103 × 355 mm; total depth 451 mm; weight approx. 7.5 kg; optional 2U rack‑mount kit.

What It Is + Why It Matters

High‑precision programmable DC electronic load for R&D, production testing, and medium‑voltage applications.
Autoranging (U/I/P) provides flexible voltage/current combinations—one unit handles diverse test conditions.
Integrated function generator (sine, triangle, rectangle, trapezoid, DIN 40839, arbitrary, ramp) and resistance simulation eliminate external waveform sources.
Battery discharge test (static/dynamic) with Ah/Wh counters and MPPT tracking (4 modes) for solar panel characterisation.
Galvanically isolated analog 0‑5/10 V interface plus USB and Ethernet (ModBus RTU/SCPI) ready for ATE integration.

Note: The peak power of 1000 W is available for a limited time; steady‑state power is 900 W at 25 °C. The internal temperature‑dependent derating reduces power gradually.

Integration & Installation

Desktop enclosure with carrying handle/tilt stand; can be installed in a 19″ rack using the optional 2U mounting frame (order nr. 10 400 111).
Front panel: DC input terminals (clamp & plug; 4 mm system plugs for max. 32 A, spade lugs for ≤36 A), USB‑A, remote sense, control panel.
Rear panel: AC inlet with fuse (T 2 A), USB‑B, Ethernet, 15‑pole Sub‑D analog interface.
Cooling: temperature‑controlled fans; leave ≥30 cm clearance behind the unit.
DC wiring: for 36 A, recommended cable cross section ≥10 mm² (AWG8) up to 5 m.

Best for / Not for

Best for: medium‑voltage power supply testing, DC‑DC converter validation, battery discharge profiling, solar panel MPPT characterisation, production ATE, and R&D laboratories.
Not for: sources exceeding 200 V / 36 A / 1000 W; series connection of loads not permitted.

Selection Checklist + RFQ

Confirm source voltage ≤ 200 V, current ≤ 36 A, sustained power ≤ 900 W (peak ≤1000 W).
Select regulation mode (CV/CC/CP/CR) and set OVP/OCP/OPP thresholds for source protection.
Choose remote interface: USB, Ethernet (ModBus/SCPI), or galvanically isolated analog (0‑5/10 V).
If rack mounting is required, order the optional 2U mounting frame (10 400 111).
For battery or MPPT testing, verify that the built‑in function parameters match your test profile.
Ensure adequate ventilation; the temperature‑dependent derating allows 1000 W peak before settling to 900 W steady.
