The DPS‑50 is a compact, dependable constant-current DC power supply engineered primarily for small to medium-sized electromagnets used in physics laboratories. Though originally designed for pairing with the EMU‑50 electromagnet, it can drive virtually any inductive coil with resistance up to 6 Ω. Its IC‑based current regulation and matched semiconductor transistors ensure stable output under varying loads, while built‑in protections guard against overload, short-circuit, and transient spikes typically caused by inductive loads .
✓ Current range: 0–4 A, smoothly adjustable
✓ Load regulation: ±0.1% across the full range
✓ Line regulation: ±0.1% for ±10% mains swings
✓ Digital readout: 3-digit 7‑segment LED display showing output current
✓ Power requirements: 220 V ±10%, 50 Hz
✓ Robust and portable: weight ~9 kg; dimensions ~ 335 × 305 × 155 mm
Ideal for electromagnets in physics teaching, precision coil excitation, and controlled current supply in educational or R&D environments.
