Buffer power supply 240W 24V 10A DRS-240-24

Buffered power supply for security and automation systems

This 240W buffered power supply, operating at 24V, is a reliable solution to ensure uninterrupted power supply in alarm systems, monitoring, emergency lighting and industrial automation. The device combines the functions of a stabilized power supply and a battery charger, offering comprehensive protection against power outages. Thanks to the ability to connect a battery, in the event of a mains failure, the power supply automatically switches to battery power, guaranteeing uninterrupted operation of connected devices.

Versatility and functionality

The power supply is characterized by a wide input voltage range (90-305VAC, 127-431VDC), which makes it compatible with various electrical installations. Adjustable charging current (in the range of 20-100% of the rated value) allows for optimal charging of batteries with different capacities (from 5 to 200Ah), and the ability to choose a 2- or 3-stage charging curve ensures a longer battery life. Additionally, CANBus versions allow programming of charging parameters using the external SPB-001 programmer and remote monitoring and diagnostics via the MODBus protocol.

Safety and reliability

The power supply design has been enriched with a number of protections: against short circuit (SCP), overload (OLP), overvoltage (OVP), undervoltage (UVP), overheating (OHP) and reverse battery polarity (RBP). Four relay outputs (AC OK, DC OK, CHARGER FAIL, BATTERY LOW) and LEDs indicate the operating status of the device and allow for quick identification of potential problems. Compliance with safety standards and high efficiency (up to 92%) guarantee long-term and trouble-free operation. DIN rail mounting simplifies installation and integration with existing systems.
