Product catalog summary

Introduction
BLOCK is a German company that specializes in high-quality power supply products, including switched mode power supplies, electronic circuit breakers, uninterruptible power supplies (UPS), and redundancy modules. The company focuses on energy efficiency and reliability, customizing products to meet specific application needs.

Switched Mode Power Supplies
BLOCK offers a variety of switched mode power supplies featuring BOOST technology, which provides up to 100 A for 50 ms to manage high inrush currents without over-dimensioning. The Power Vision line is recognized for its slim design, communication capabilities, and maximum power reserves, ensuring high system availability.

Electronic Circuit Breakers
These breakers allow up to 8 fused circuits to be controlled via a PLC, with digital inputs for monitoring operating and fault status, offering a cost-effective connection to higher-level control systems.

Uninterruptible Power Supplies (UPS)
BLOCK's UPS systems feature reliable battery management through continuous data exchange between the charger and controller, optimizing battery charging and signaling when replacement is needed.

Redundancy Modules
These modules ensure system reliability by providing backup power in case of primary power supply failure.

Product Lines

Power Vision: High performance with features like Top Boost and Power Boost for handling high inrush currents, integrated monitoring, and communication interfaces.
Power Compact: Basic power supplies with essential features for high system availability, suitable for average power requirements.
Power Mini: Efficient supplies in slim casings for lower power needs, with low standby loads and robust mounting options.
Power ECO LINE: Designed for distribution boards, offering vibration-resistant terminals and constant current limiting.
Power PRINT: Compact supplies for direct circuit board soldering, providing high efficiency and low standby losses.

Key Features and Technologies

BOOST Technology: Provides temporary increased power supply for reliable circuit breaker operation.
Monitoring Capabilities: Includes input/output voltage and current monitoring, fault visualization, and communication interfaces for system integration.
Installation and Connectivity: Features like push-in connection technology and robust support rail mounting facilitate easy installation.

Specifications
The document outlines the disconnection time for circuit breakers, which ranges from 4-12 milliseconds for short-circuits. It emphasizes the importance of maintaining continuous total resistance in the conductor loop for reliable operation. The maximum possible current is determined by the conductor cross-section, length, and contact resistance.

Protective Coating
For harsh environmental conditions, a protective coating is recommended to prevent short circuits caused by dirt and dust, and to avoid erosion of conductors and soldering joints. This coating does not alter the electrical properties of the power supply.

Electronic Circuit Breakers
Designed to work with switched mode power supplies and DC 24V loads, these breakers offer reliable disconnection even with high line impedances and allow for remote switch-on of disconnected channels. They distribute load current across several branches and monitor for overloads and short-circuits.

Advantages
Electronic circuit breakers can handle high line resistances, variable rated current per channel, and sequential power-up of channels to manage inrush current. They also offer communication with central control systems using minimal wiring.

Applications
These circuit breakers are suitable for applications where traditional thermomagnetic circuit breakers may not provide reliable protection, particularly in environments with high capacitive loads and limited space in switch cabinets.

Operational Procedures
The circuit breakers ensure reliable switching on of high-capacity loads and selective shutdown of defective circuits. They provide continuous monitoring of current and voltage, with visual indicators for operational status and faults. The Power Vision series supports communication via LEDs, display, signal outputs, and interface.

Uninterruptible Power Supplies (UPS)
Designed for reliable 24 VDC supply, even during power failures, these systems include battery management for optimal charging and longevity, with features like automatic recognition of battery modules and early warning signals for battery replacement. They support controlled shutdown and restart of industrial PCs.

Recommendations
For maximum system availability and process reliability, it is recommended to use the integrated monitoring and communication features of the Power Vision series. Regular monitoring and maintenance of battery modules are advised to ensure optimal performance and longevity.

Conclusion
BLOCK's power supply solutions are designed to meet diverse application needs with a focus on reliability, efficiency, and advanced monitoring capabilities. Their products are suitable for a wide range of industrial and automation technology applications.
