UPS buffer module 24~29V 40A DUPS40

UPS Buffer Module – Reliable Power Supply in DC Systems

The DUPS40 is a UPS module designed for DIN rail mounting, which, combined with a power supply and battery, creates an uninterruptible power supply (UPS) system. Its main task is to ensure the continuity of operation of devices in the event of a power failure. This module finds application in many areas, from data centers to monitoring and emergency lighting systems.

Functionality and application

DUPS40 is designed to operate at a voltage of 24~29V DC and can handle a current of up to 40A. This makes it ideal for protecting power circuits for various types of devices requiring stable and uninterrupted power. The built-in battery test function allows for regular monitoring of its condition, and reverse polarity protection protects the module from damage during incorrect connection.

This module works particularly well where even short power outages can cause serious problems – e.g., in alarm systems, access control or industrial automation. Thanks to its compact dimensions (63x125.2x113.5mm), it is easy to mount in a limited space.

Key features and benefits

• Automatic switchover to battery power: ensures continuous operation of devices without manual intervention.
• Built-in battery test function: enables regular monitoring of the battery condition and prevents failures caused by its discharge or damage.
• Reverse polarity protection: protects the module from damage during incorrect battery connection.
• LED signaling and relay connections: inform about the status of the DC power bus, failure and battery charge level, which facilitates diagnostics and maintenance of the system.
• Designed for DC bus: easy integration with existing power supply installations.
• Wide input voltage range (24~29V): ensures compatibility with different types of batteries and power supplies.
• Open-air convection cooling: ensures reliable operation even in harsh environmental conditions (operating temperature -30~+70°C).
• 3-year warranty: confirms the high quality of the product and provides peace of mind for the user.

Thanks to these features, DUPS40 is a reliable solution for anyone who needs to ensure continuous power to critical devices.
