Type 78.X1 and 78.Y1: Provide outputs of 240 W and 480 W, featuring active power factor correction (PFC) and high peak current capabilities.
Type 78.1A and 78.2A: Designed for high efficiency up to 94%, suitable for PLC power supply, and feature LLC topology.
Type 78.1B and 78.1D: Offer outputs of 120 W and 130 W, with fold-back overload characteristics and active PFC.
Type 78.2E: Provides a 240 W output with forward topology and active PFC.
Type 78.H2 and 78.W2: Designed for dual-phase wide input range, offering outputs of 60 W and 120 W, with auxiliary contact for DC OK.

Procedures: Instructions for resetting the power supply following thermal protection intervention by removing the supply voltage. Details on feedback contact switching mode for pre-alarm conditions.

Wiring Diagrams: Detailed wiring diagrams for various models, including basic connections, dual polarity connections, series connections, and parallel connections.

Components and Accessories: Lists components such as diodes and heat sinks required for certain models, and accessories like marker tags for labeling purposes.

Outline Drawings: Includes outline drawings for various models, showing the box clamp design for each type.

Key Recommendations: Ensure proper installation and connection as per the wiring diagrams to avoid operational issues. Regularly check LED indicators for any anomalies and reset the power supply as instructed in case of thermal protection activation.
