Model: SE-450

SE-450 450W Single Output Switching Power Supply | SE-450

Overview

The 450W single output switching power supply (SE-450) is a constant-voltage LED driver designed for robust and reliable operation in various lighting applications. It delivers a stable power output of 450W, making it suitable for powering extensive linear LED installations or multiple fixtures. Featuring CE and UL certifications, this unit ensures compliance with international safety and performance standards. It is ideal for architectural linear lighting, commercial displays, and other B2B LED lighting projects requiring consistent power delivery.

Description

This 450W single output switching power supply features AC input inrush current limiting and switch-selectable input voltage for architectural lighting systems. Comprehensive multi-protection circuitry defends connected LED strip light installations against short circuits, overloads, overvoltage, and overtemperature conditions. A built-in DC fan provides forced air cooling alongside integrated remote sensing capabilities to maintain stable output during continuous operation. Manufactured for wholesale project supply, this robust single output power supply includes a 2-year warranty for demanding commercial lighting deployments.

Applications

  • Cove, wall-wash & perimeter lighting — Coves, recesses, wall-wash details and ceiling perimeters where a continuous, uniform line of light is required.
  • Showroom & hospitality display lighting — Shelving, display cases, reception desks and signage backlighting in shops, showrooms and hospitality spaces.
  • Kitchen & wardrobe under-cabinet lighting — Kitchen, wardrobe and furniture task lighting where the strip stays hidden and only the light is seen.

Frequently Asked Questions

What are the primary electrical specifications of the SE-450 power supply?

The SE-450 is a 450W single output switching power supply, providing a constant voltage output. Specific voltage options typically range from 12V to 48V DC, depending on the model variant. It is designed for efficient power conversion, ensuring stable operation for connected LED loads.

What certifications does the SE-450 possess, and why are they important for B2B applications?

The SE-450 power supply holds CE and UL certifications. These signify compliance with European safety, health, and environmental protection standards (CE) and North American safety standards (UL). For B2B applications, these certifications are crucial for market acceptance, regulatory compliance, and ensuring product safety and reliability in commercial installations.

Can this 450W single output switching power supply be used in outdoor or damp locations?

The standard SE-450 model typically features an IP20 rating, indicating suitability for dry indoor environments. For outdoor or damp location applications, a power supply with a higher IP rating (e.g., IP65 or IP67) is required to ensure protection against moisture and dust ingress. DENO offers various power supply options for different environmental conditions.

Is the SE-450 suitable for dimmable LED strip light installations?

The SE-450 is a non-dimmable constant voltage power supply. To achieve dimming for LED strip light installations, a separate dimming module or a dimmable power supply with integrated dimming capabilities (e.g., 0-10V, DALI, PWM) would be required. The SE-450 provides stable power, and dimming control would be implemented on the secondary side.
