DC-DC Converter BCS BCS-SD15/12 48V DC to 12V DC

BCS-SD15/12 is a DC-DC converter that converts 48V DC input to a regulated 12V DC output. The module is intended to supply 12V devices from a 48V power infrastructure without changing the supply source type. It is suitable for applications where a stable low-voltage supply is required from a higher-voltage DC bus, including CCTV cameras, telecommunication equipment, control systems and various industrial electronics.

Advantages

The converter provides a stable 12V output with protection features appropriate for powering sensitive electronics. Its compact design allows integration into existing power racks or enclosures fed from a 48V distribution line. The unit minimizes the need for separate 12V power supplies and reduces cabling complexity when 48V infrastructure is already present. Designed for continuous operation, it supports reliable voltage conversion in systems with varying load conditions.

Suitable for

• Powering 12V CCTV cameras and recording equipment from 48V installations
• Supplying telecommunication modules and remote units that require 12V
• Integration into control panels and industrial automation systems
• Providing 12V power to sensors, relays and low-voltage electronic modules

Key specifications

• Input voltage: 48V DC
• Output voltage: 12V DC (regulated)
• Designed for continuous operation to supply low-voltage loads from a higher-voltage bus
• Compact form factor suitable for rack or enclosure mounting
• Intended for use in CCTV, telecom, control and industrial electronics environments

How to use

Connect the converter’s input terminals to the 48V DC supply according to the system wiring standards and polarity. Connect the 12V DC output to the load, observing correct polarity and ensuring that the combined load current does not exceed the converter’s rated output capability. Mount the unit in a location with adequate ventilation and away from direct heat sources. Follow standard safety procedures when making connections and power up the system while monitoring the output voltage to confirm proper operation.

Usage recommendations

For reliable operation, verify that the 48V supply is stable and within expected tolerance before connecting sensitive loads. Use appropriately sized wiring and fusing on both input and output circuits. Allow sufficient ventilation around the converter, and place it in an environment within the manufacturer's specified operating temperature and humidity ranges. When integrating into critical systems, consider adding surge protection and periodic inspection of terminals and mounting.
