Mean Well HDR-30-24 9-36V Input, 24V/1.25A Output

Ultra-Slim DIN Rail Design: Compact 35mm (2SU) wide housing mounts directly onto standard TS-35/7.5 or TS-35/15 DIN rails, saving critical space inside industrial control cabinets.

30W 24V Regulated Output: Efficiently converts low DC input voltage into a stable 24V DC output up to 1.25A (30W max) for industrial control equipment, PLCs, and automation systems.

Wide DC Input Compatibility: Accepts a flexible wide DC input voltage range of 9V–36V DC, ideal for solar power arrays, battery-backed installations, vehicle electronics, and low-voltage bus systems.

Fine-Tuning Voltage Trim: Onboard potentiometer (V_ADJ) allows fine calibration of the 24V output rail (21.6V–29V) to offset line resistance loss over longer cable runs.

Class II Insulation (No Ground Pin Required): Flame-retardant plastic enclosure engineered to Class II safety standards, eliminating the need for an Earth ground connection.

Comprehensive Multi-Protection Suite: Integrated circuit protection guards against output short circuits, continuous current overload, over-voltage spikes, and input reverse polarity.

Housing & Casing Style: Flame-retardant step-shaped plastic casing (UL94V-0) engineered for TS-35 DIN-rail mounting and natural convection airflow.

Contact & Terminal Style: Touch-safe screw terminal block connectors (DC Input: +Vin, -Vin; DC Output: -V, +V).

Technical Specifications:
