Special Feature

Resistance

30-Second Fit Check

Output: 0-200V, 0-50A, 3000W with true autoranging (U/I/P).

AC input: 110-127V / 208-240V ±10% (single phase or two-phase), 45-65Hz. On 110V input, output derates to 1500W.

Efficiency: ≤94.5% at full load and full output voltage.

Regulation: Load regulation CV ≤0.05% FS, line regulation ≤0.01% FS.

Ripple: 30mV rms / 300mV pp (CV mode, 300 kHz / 20 MHz BW).

Protections: Adjustable OVP, OCP, OPP, plus OT, PF.

What It Is + Why It Matters

Mid-voltage high-current programmable DC power supply for battery testing, DC motor drives, industrial automation, and R&D labs.

Autoranging output delivers full 3000W across wide voltage/current range – no manual range switching.

Built-in internal resistance simulation (0.1Ω – 250Ω adjustable) for battery and load emulation.

Master-Slave parallel operation – up to 64 units for 192kW total power; true current sharing via Share bus and digital MS bus.

High stability: temp coefficient CV ≤30ppm/°C after warm-up.

Note: Remote sensing compensates up to 5% of U_Nom. Always use DC terminal covers when hazardous voltages present.

Built-in analog interface (15-pin D-Sub): 0-5V / 0-10V selectable range for set/readback of U/I/P/R; includes remote on/off, alarm outputs (OT/OVP/OCP/OPP), and CV/CC status.

Optional plug-in modules (IF-AB series): Profibus, ProfiNet, CAN, CANopen, RS232, ModBus TCP, EtherCAT – installable without opening the device.

Web server on LAN port for network configuration and manual SCPI commands.

Remote sense for voltage drop compensation (max 5% of U_Nom).

Best for / Not for

Best for: Battery charging and cycling (Li-ion, lead-acid up to 200V), DC motor and servo drives, industrial power supplies, capacitor charging, and general R&D lab use requiring 200V/50A.

Not for: Applications requiring output above 200V or above 50A per single unit (use master-slave parallel to scale current); applications needing bidirectional energy recovery (consider PSB series).

Selection Checklist + Integration

Confirm AC supply: 208-240V recommended for full 3000W; on 110-127V derated to 1500W.

DC cable cross-section: For 50A / 5m length, use at least 16mm² (AWG6); for longer runs increase cross-section or use parallel cables.

Mounting: 19" rack, 2U height, allow >30cm rear clearance for airflow.

For master-slave parallel: Connect Share bus (BNC) and MS bus (RJ45 CAT5); configure termination (BIAS/TERM) per manual.

For remote sense: Use included sense plugs to compensate voltage drop at load terminals.

For internal resistance mode: Activate R mode in the quick menu to simulate battery internal resistance.

Firmware: KE/HMI 3.02+ recommended for SEMI F47 support.
