DR-240-24 Industrial DIN-Rail Switching Power Supply (24V 10A 240W)

Architectural Overview
The DR-240-24 is a high-efficiency 240W industrial-grade DIN-rail switching power supply engineered to deliver a stabilized 24V DC output at up to 10A continuous current. Designed with advanced primary-side switching topologies and an integrated active Power Factor Correction stage (PF >0.98 at 115VAC, PF >0.95 at 230VAC), it provides clean, consistent DC rail energy with minimal harmonic distortion. The input stage accommodates broad operating ranges spanning 85-264VAC (47-63Hz) and 120-370VDC, ensuring dependable energy conversion across unstable grid environments while suppressing ripple and noise below 120mV with a tight ±1% output voltage accuracy.

Material & Engineering Design
Engineered inside a ruggedized, corrosion-resistant metallic enclosure, the unit integrates precision internal galvanic isolation rated at 3KVAC (I/P-O/P) and 1.5KVAC (I/P-FG). The mechanical footprint of 125.5 x 100 x 125.2 mm is optimized for high power density within control cabinets. Heavy-duty screw clamp terminals facilitate vibration-resistant terminations for high-gauge single-phase input and DC distribution wiring, ensuring minimal contact resistance and sustained industrial longevity under sustained heavy mechanical shock.

Operational Endurance & Thermal Dynamics
Built for harsh plant environments, the power supply sustains continuous operation across ambient temperatures from -10°C to +50°C and 20% to 90% non-condensing relative humidity. Integrated protection circuits safeguard against overloads (105% to 150% with automatic burp-mode recovery), output overvoltage (>135%), short circuits, and thermal runaway. A dedicated thermal sensor interrupts output delivery if chassis temperatures breach 85°C, recovering safely once standard thermal envelopes are restored after system cycling.

Fast and labor-saving installation, single-phase AC output, with short-circuit, overload, over-temperature, over-voltage protection

Compatibility & Installation Standards
Designed for fast, labor-saving snap-on deployment, the unit mounts directly onto standard TS-35/7.5 or TS-35/15 industrial DIN rails without specialized tooling. Its tight line and load adjustment metrics (±0.5% and ±1% respectively) make it fully compatible with sensitive programmable logic controllers (PLCs), distributed I/O blocks, industrial HMIs, DC motor drives, edge gateways, and secondary distribution enclosures.
