Finder expands 78 Series industrial switching power supplies

Finder is expanding its range of 78 Series industrial switching power supplies, introducing innovative models in single-phase, two-phase, and three-phase configurations.

In the dynamic landscape of industrial automation and electrical panel design, Finder is expanding its range of Series 78 industrial switching power supplies, introducing innovative models in single-phase, two-phase, and three-phase configurations.

Single-Phase Power Supplies: Compactness and Energy Efficiency
The Series 78 single-phase switching power supplies have been engineered to deliver high efficiency within a compact form factor, while maintaining low stand-by consumption. All models provide a nominal output voltage of 24 V DC, precisely adjustable between 24 and 28 V, to meet specific load requirements.

The single-phase range is structured into four versions, optimized for various output power ratings:

- Type 78.J1.1.230.2402: 75 W unit, characterized by reduced dimensions.
- Type 78.W1.1.230.2402: 120 W model, balancing power and compactness.
- Type 78.X1.1.230.2412: 240 W solution, featuring a double stage with PFC (Power Factor Correction) to ensure high quality of absorbed energy.
- Type 78.Y1.1.230.2412: The flagship 480 W model, also featuring a double stage with PFC, ideal for more demanding loads.

The integration of PFC technology in the 240 W and 480 W units ensures regulatory compliance and optimization of electrical energy usage.

Two-Phase Power Supplies: Wide Input Voltage Range and Signaling Contact
The new two-phase offering introduces four types of power supplies, designed to ensure maximum operational flexibility. These devices stand out for their wide input voltage range, which facilitates integration in contexts with fluctuations or specific grid voltages.

A key feature of the two-phase version is the presence of a DC OK clean contact on all models, providing essential signaling regarding the correct operating status of the power supply. In this configuration, the output is also 24 V DC, adjustable between 24 and 28 V.

The available models are:

- Type 78.H2.1.440.2404: 60 W with clean contact: DC OK.
- Type 78.W2.1.440.2404: 120 W with clean contact: DC OK.
- Type 78.X2.1.440.2414: 240 W, with clean contact: DC OK and double stage with PFC.
- Type 78.Y2.1.440.2414: 480 W, with clean contact: DC OK and double stage with PFC.

Three-Phase Power Supplies: Maximum Power and Integrated Paralleling
For applications demanding maximum power and robustness, Finder proposes the three-phase version. These power supplies have been developed to operate with a wide input voltage range and also offer output regulation between 24 and 28 V, along with the DC OK clean contact.

The three-phase configuration includes three high-performance models, all equipped with a double stage with PFC:

- Type 78.X3.1.440.2414: 240 W.
- Type 78.Y3.1.440.2414: 480 W.
- Type 78.Z3.1.440.2414: The top-of-the-range 960 W unit. This model is distinguished by its capability to be directly parallelable with an internal clock, a crucial feature for systems requiring redundancy or higher aggregate power, ensuring stability and synchronization.
