Dehner Elektronik Sunpower SDS 036M-15 DC/DC Converter 36W 15V 2.4A Isolated

The SDS 036M-15 from Dehner Elektronik's Sunpower series stands out with its rugged industrial design and wide 9–36 V DC input range, making it suitable for demanding applications where input voltage fluctuates significantly. Unlike many commodity converters, it provides full galvanic isolation up to 1500 V DC, protecting sensitive loads from ground loops and transient spikes. With a compact 1" x 1" industry-standard footprint and through-hole mounting, it integrates easily into existing PCB designs while delivering a stable 15 V output at up to 2.4 A.

Highlights

• Wide 4:1 input range (9–36 V DC) for 12 V and 24 V battery systems
• Isolated output with 1500 V DC isolation voltage
• High efficiency up to 90% reduces heat and energy waste
• Continuous short-circuit and overcurrent protection
• Remote on/off control for power sequencing
• Operating temperature range from -40 °C to +85 °C
• RoHS and CE compliant

In daily use

This converter is ideal for industrial automation, transportation, telecommunications, and battery-powered equipment. Its wide input range handles cold-crank voltage dips in vehicles and brownouts in industrial plants. The isolated output eliminates noise coupling between input and output, ensuring clean power for sensitive analog circuits. The remote on/off pin allows the converter to be disabled by a logic signal, saving power in standby modes. With a mean time between failures (MTBF) exceeding 1 million hours, it offers long-term reliability in mission-critical installations.
