NEC ENT-10515-R AC

Technical Specifications: Input voltage ranges from 85–264 VAC, and input frequency ranges from 47–63 Hz. Output voltage is 24 VDC ±10%, output current is 5 A, and rated power is 120 W. Conversion efficiency reaches ≥95%. Operating temperature ranges from -20°C to +70°C, storage temperature ranges from -40°C to +85°C, and protection class is IP20. Dimensions are 120 mm × 90 mm × 34 mm (W × D × H), and weight is approximately 0.5 kg. It holds CE, UL, and CSA certifications.

Functional Features: Its wide input voltage range adapts to global power grid standards. High conversion efficiency reduces energy loss and heat generation. It has built-in overvoltage, overcurrent, and short-circuit protection. Its compact form factor saves installation space, and low ripple and noise output ensures stable power for sensitive devices.

Application Scenarios: It applies to industrial automation control cabinets, power supply for industrial Ethernet switches, power distribution for field sensors and actuators, building automation system power supply, and telecommunication and data communication equipment.

Performance Parameters: Load regulation is ±0.5%, and line regulation is ±0.2%. Output ripple is less than 100 mVpp. Hold-up time is minimum 20 ms at full load. Mean time between failures exceeds 200,000 hours.

Material Composition: The housing is a metal shielded enclosure with powder coating. Internal components adopt industrial-grade semiconductor devices and passive components. Heat dissipation structure uses aluminum alloy heat sink. Input/output connectors adopt industrial-grade terminal blocks.

Structural Features: It features a compact DIN-rail or panel mount design, front-facing power and status indicators, screw terminal connections for reliable wiring, and an integrated heat dissipation structure for natural cooling.

Working Principle: The power supply converts AC input voltage to DC through rectification and filtering circuits, then performs high-frequency DC-DC conversion through a switching power supply topology, and outputs stable 24 VDC voltage after output filtering and voltage regulation. The internal control circuit maintains output stability and triggers protection mechanisms in case of abnormal conditions.

Installation Requirements: Install the unit vertically with sufficient surrounding space for heat dissipation. Ensure input wiring complies with local electrical safety standards. Use appropriate wire gauge based on output current, and verify reliable grounding of the power supply and equipment.

Precautions for Use: Do not operate beyond the specified input voltage and output load range. Do not use in environments with conductive dust or corrosive gases. Disconnect power before wiring or maintenance operations. Do not open or modify internal circuits, and perform regular inspection of wiring connections and cooling conditions.
