Inission Power SLP420 - 420 W AC/DC Power Supply for LED Lighting and Industrial Applications
48 V Output at 94% Efficiency in a Compact Open Frame Package
LED lighting systems, entertainment lighting, industrial laser applications, and video wall displays share a common power supply requirement: a reliable, high-efficiency 48 V DC source that can sustain high output power continuously, operates across all global mains voltages, and fits within a compact open frame that integrates easily into the host system's mechanical design.
The Inission Power SLP420 has been developed specifically for these applications. Delivering 420 W with forced-air cooling and a sustained 330 W under natural convection, the SLP420 provides a regulated 48 V DC output in a 3.0" × 5.0" × 1.5" open frame package with 94% typical efficiency - meeting the demands of power-intensive lighting, industrial, and display applications within a minimal footprint.
Designed for LED Lighting, Industrial, and Display Applications
The SLP420 is suited for use across a range of applications where a high-power, high-efficiency 48 V supply is required, including:
- Entertainment lighting: LED moving heads, spots, and strobes
- Architectural and stage lighting systems
- Video wall displays and solid-state lighting (SSL)
- Industrial laser applications
- 3D printing equipment
- Automated teller machines (ATMs)
Technical Characteristics
The SLP420 combines high output power with a broad set of electrical and environmental characteristics suited to demanding system integration:

Convection and Forced-Air Operation from One Platform
A practical advantage of the SLP420 for system designers is its dual-mode thermal capability. At 330 W continuous output in natural convection, it covers a substantial proportion of typical LED driver and industrial load requirements without requiring any forced airflow - useful in sealed or low-airflow enclosures where fan noise or dust ingress is a concern. When forced air is available, the same unit delivers its full 420 W rated output, allowing system designers to specify a single power supply model across both fanless and ventilated configurations within a product family.
The adjustable output voltage trim from 48 V to 51 V DC provides flexibility for battery charging applications or systems requiring a slightly elevated DC bus voltage without additional external regulation components.
FORTEC Switzerland supports you in selecting the right SLP420 configuration for your application - from initial evaluation through to project-specific procurement and long-term series supply.
