Finder Expands 78 Series with Industrial Power Supplies

Industrial automation, electrical distribution panels, and control systems require stable and efficient 24 V DC power supplies, and Finder expands its 78 Series with new switch mode power supplies designed to cover a broad range of power requirements and installation environments.

Finder has introduced new single-phase, dual-phase, and three-phase switch mode power supplies within its 78 Series, extending the portfolio to address applications from residential and commercial panels to high-power industrial automation systems.

Scalable Power Across Single-Phase Systems
The single-phase range includes four models with output power from 75 W to 480 W, all providing 24 V DC output adjustable between 24 and 28 V. Lower-power units (75 W and 120 W) are designed with compact form factors and low standby power consumption, making them suitable for space-constrained installations.

Higher-power variants (240 W and 480 W) incorporate a two-stage design with Power Factor Correction (PFC), improving energy efficiency and ensuring compliance with industrial power quality requirements.

Dual-Phase Models with Monitoring Capabilities
The dual-phase versions extend the same power range from 60 W to 480 W while supporting a wide input voltage range. These models include a volt-free “DC OK” contact, enabling remote monitoring of output status in control systems.

As with the single-phase range, higher-power models integrate PFC, supporting stable operation in industrial environments where load conditions may vary.

Three-Phase Power Supplies for High-Demand Applications
For applications requiring higher power levels, the three-phase range offers outputs up to 960 W. These models are designed for industrial systems with significant energy demands, such as machinery, process automation, and large control cabinets.

All three-phase units feature adjustable 24 V DC output and PFC, with the highest-power model supporting parallel operation through internal synchronization. This enables scalable power configurations for systems requiring redundancy or load sharing.

Design Considerations for Industrial Integration
Across the range, the adjustable output voltage allows adaptation to specific system requirements, while PFC-enabled designs improve efficiency and reduce harmonic distortion on the supply network.

The inclusion of monitoring contacts in dual- and three-phase models supports integration into automation systems where power status feedback is required for diagnostics and maintenance.

Positioning Within Power Supply Solutions
With the addition of these models, the 78 Series now covers a wide spectrum of applications, from low-power control panels to high-demand industrial systems. Compared with fixed-output or single-phase-only solutions, this expanded range provides greater flexibility in system design and deployment.

By offering multiple phase configurations and power levels within a unified product family, Finder enables engineers to standardize power supply selection across different project scales while maintaining consistent performance characteristics.
