DRL-48V480W1EN Delta Lyte II 48V 480W DIN Rail Power Supply

Product Overview

The DRL-48V480W1EN is a premium industrial DIN rail power supply from Delta's high-efficiency series. Engineered to deliver a stable 48V DC output at a 10A current rating, this 480W power supply features an ultra-slim form factor that maximizes cabinet space. With its robust build quality, it provides reliable, high-power density energy conversion for demanding industrial automation environments.

Key Advantages

• Reactive Load Handling: Equipped with a built-in constant current circuit that easily manages heavy inductive or capacitive reactive loads during startup surges.
• Slim Space-Saving Profile: The space-conscious 56mm width design permits tightly packed DIN rail mounting, significantly reducing overall enclosure sizing.
• Extreme Environment Operation: Engineered to withstand harsh plant floors, performing reliably across an ultra-wide temperature envelope from -40°C up to +70°C.
• Energy Efficiency & Compliance: Optimizes power usage with reduced no-load power consumption and meets strict SEMI F47 industrial voltage sag immunity standards at 200 Vac lines.

Technical Specifications

Quick Installation Tips

• Snap the unit vertically onto standard 35mm DIN rails, ensuring the input terminals face downward to promote natural cooling convention.
• Leave a minimum recommended ventilation clearance above and below the device when integrating it adjacent to other power components inside compact panels.
• Verify that the source AC line voltage falls within the flexible 90-264 Vac range prior to applying power to protect the internal regulatory circuitry.

Technical FAQs

Q1: How does the constant current circuit assist with reactive loads?

A1: When running motors, solenoids, or heavy capacitive filters, startup current spikes can trigger standard power supplies to shut down. The DRL-48V480W1EN stays operational by switching to constant current mode to sustain power delivery without entering a protection fault state.

Q2: What is the significance of the SEMI F47 compliance standard?

A2: SEMI F47 indicates that the power supply can ride through voltage sags on the utility grid without dropping its 48V DC output load, which is critical for preventing costly downtime in semiconductor and precise process automation lines.

Q3: Does the unit require an external cooling fan at +70°C?

A3: The unit is designed for natural convection cooling. While it can operate up to +70°C, typical industrial thermal management mandates output power derating above a certain temperature threshold (refer to the official manual's derating curves).
