Mean Well HDR-30-12 DC Power Supply 12V 2A

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 valuable control cabinet space.

30W 12V Regulated Output: Delivers a reliable 12V DC output up to 2A (24W–30W max), engineered to supply clean power to industrial control systems and automation equipment.

Universal AC Input Range: Accepts a wide input voltage range of 85V–264V AC (47–63Hz) or 120V–370V DC, offering global versatility with low no-load power consumption (<0.9W).

Adjustable Output Voltage: Onboard potentiometer (V_ADJ) allows fine-tuning of the 12V output rail (10.8V–13.8V) to compensate for voltage drop across longer wiring runs.

Double Isolation (Class II Safety): Plastic isolated housing with no Earth ground (FG) pin required, meeting Class II isolation standards for safe indoor and cabinet deployments.

Comprehensive Protective Suite: Built-in automatic protection guards connected loads against short circuits, continuous current overloads, and over-voltage conditions.

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

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

Technical Specifications:

Model: HDR-30-12.

Input Voltage: AC 85V–264V (47–63Hz) / DC 120V-370V.

Output Voltage: DC 12V (Adjustable 10.8V–13.8V).

Output Current: 0A–2A Max.

Rated Power: 24W (2A continuous).
