HDR-30 Ultra-Slim Step-Shape DIN Rail Power Supply (12V/24V 30W)

Architectural Overview
The HDR-30 series delivers highly efficient, ultra-compact switch-mode power conversion engineered for modern industrial distribution boards and building automation systems. Supporting universal AC input voltages ranging from 85VAC to 264VAC (or 120VDC to 370VDC), this 30-watt power supply provides isolated, precision-regulated continuous DC output across both 12V and 24V configurations. Featuring an ultra-low no-load power consumption of under 0.3W and Class II double insulation design without requiring a protective ground terminal, the architecture maximizes electrical safety and energy savings in high-density automation arrays.

Material & Form-Factor Design
Constructed within an ultra-compact 35mm (2SU) step-shaped flame-retardant thermoplastic housing (UL 94V-0 certified), the unit seamlessly interfaces with standard TS-35/7.5 and TS-35/15 DIN rails. The heavy-duty captive screw terminal blocks accept wiring up to 12 AWG, guaranteeing vibration-proof conductor termination under high mechanical stress. The front panel incorporates an accessible DC output potentiometer for fine voltage trimming along with an integrated LED operational status indicator for rapid visual diagnostics within closed breaker panels.

Operational Endurance & Protection
Engineered for mission-critical reliability, the HDR-30 features comprehensive active safety mechanisms, including constant current limiting for over-current scenarios, over-voltage clamping, and auto-recovery short-circuit protection. Convection cooling maintains low internal thermal gradients across broad operational environments from -30°C to +70°C without requiring forced-air fans. With high MTBF ratings exceeding 900,000 hours per Telcordia SR-332 and safety compliance across EN61558-2-16, EN62368-1, and UL508, the unit guarantees sustained continuous uptime.

Integration & System Compatibility
Optimized for rapid integration within industrial IoT cabinets, programmable logic controller (PLC) topologies, distributed smart home systems, and low-voltage field instrument loops. Its standardized low-profile enclosure matches European distribution breaker form-factors, allowing direct mounting alongside miniature circuit breakers and industrial switching relays. This design delivers pure, filtered DC power with low ripple and noise to telemetry modules, edge gateways, access control hardware, and remote sensory nodes.
