Leader 775-5D

The Leader 775-5D is a single-output DC power supply engineered for laboratory, educational, and production environments. It delivers 0–75 V DC at 0–5 A with automatic constant voltage/constant current crossover, adjustable current limiting, and remote sense terminals for lead-drop compensation. A 3½-digit LED display provides real-time voltage and current monitoring at ±0.5% rdg ±2 digits accuracy. The unit operates across switch-selectable input voltages (100 V, 120 V, 220 V, or 240 V ±10%, 250 V max) at 50/60 Hz and includes automatic overload recovery.
