COSEL FDA Series - 50 W to 200 W Enclosed AC/DC Power Supply with Wide Single-Phase Input
50 W to 200 W in a Compact Enclosed Package with Full-Range Single-Phase Input
Industrial, energy, and infrastructure systems operating across diverse global markets face a recurring power supply challenge: the AC input voltage available at the point of installation varies widely, from 200 V systems common in Asia and North America to 400 V European industrial supplies. Designing separate power supply variants for each voltage environment adds cost, complicates procurement, and fragments the spare parts inventory.
The COSEL FDA Series resolves this with a single-phase AC input range of 180-528 V AC - covering all standard global single-phase grid voltages in one platform. Available in four power levels from 50 W to 200 W, the series is engineered for industrial control, energy systems, and infrastructure applications where reliable, convection-cooled operation over a wide temperature range is required. FORTEC Switzerland offers the FDA Series as part of its COSEL power supply portfolio.
Designed for Industrial and Energy Applications
The FDA Series is suited for deployment in a range of industrial and energy applications, including:
- Industrial control and automation systems
- Energy infrastructure and renewable energy installations
- Process control equipment
- Factory automation and machinery
- Infrastructure installations operating across mixed-voltage environments
Technical Characteristics
The FDA Series provides a consistent set of electrical and environmental specifications across all four power levels, with full compliance to international safety and EMC standards:
- Single-phase AC input: 180-528 V AC covering all global grid voltages (50/75 W models also accept DC input 255-746 V; 150/200 W models accept 255-530 V DC)
- 24 V DC regulated output across the series with adjustable output range of 21.6-26.4 V
- Output power: 50 W (2.1 A), 75 W (3.2 A), 150 W (6.3 A), 200 W (8.4 A)
- Efficiency: 86-88% depending on model and input voltage
- Active Power Factor Correction on 150 W and 200 W models (power factor 0.98 at 200 V AC, full load)
- IEC 61000-3-2 Class A harmonic current compliance across the series

Optional Configurations
The FDA Series is available with several factory-configurable options that do not require custom design work: conformal coating for humidity and contamination protection, DIN rail mounting bracket for direct cabinet installation without additional hardware, and an operation LED indicator for visual power status monitoring.
Compact Enclosed Package for Easy Integration
The 50 W and 75 W models are housed in a 50 × 125 × 124 mm galvanised steel enclosure weighing up to 550 g. The 150 W and 200 W models use a 65 × 125 × 124 mm enclosure weighing up to 800 g. The enclosed construction protects internal components from the installation environment, and the adjustable output voltage potentiometer is accessible externally, allowing fine-tuning without disassembling the unit.
FORTEC Switzerland supports you in selecting the right FDA Series configuration for your application - from initial product evaluation through to project-specific procurement and long-term series supply.
