DIN rail-mounted DC power supply buffer module AMBF4 series

Buffer modules ensure secure DC power supply: - **Electrical:** - Input signal 24V DC 900mA. - Buffer discharge signal: 24V DC 20A or 40A depending on the model. - **Output Contacts:** - 2 independent contacts to signal battery discharge. - **Physical:** - Metal housing, DIN rail mountable, 4-module width. - Connection via screw terminals. - **Secure Power Supply:** - The buffer module includes a rechargeable battery to temporarily maintain power in case of stabilized power supply failure. The duration depends on the battery capacity and the power drawn. - Multiple buffer modules can be connected in parallel to increase backup power duration. The module is equipped with contacts to alert when the battery is in use. - **Compliance:** - CE, RoHs, Reach. - **Applicable Standards:** - EN55032, EN61000-3-2, EN61000-6-2, EN61204-3. **Variants and Order Codes:** | Order Code | Primary Voltage | Output Voltage | Power | Stocked Product | |------------|-----------------|----------------|-------|-----------------| | AMBF4-20-24 | 24 V DC | 24 V DC | 20A | instock | | AMBF4-40-24 | 24 V DC | 24 V DC | 40A | instock | - **Technical Papers:** - Learn more about stabilized AC/DC power supplies at Lettel **Features / Technical Specifications:** - Input signal: 24V DC 900mA - Buffer discharge signal: 24V DC 20A or 40A depending on the model - 2 independent contacts to signal battery discharge - Metal housing, DIN rail mountable, 4-module width - Connection via screw terminals - Integrated rechargeable battery - Possibility of parallel connection of multiple modules - Compliance: CE, RoHs, Reach - Standards: EN55032, EN61000-3-2, EN61000-6-2, EN61204-3
