Key Specifications
The CQB150W8 series is a high-performance 8:1 ultra-wide input DC-DC converter that delivers 150W of regulated power in a compact quarter-brick size (2.28" x 1.45" / 57.8 x 36.8 mm). It is IEC/UL 62368-1 certified and features 3000Vac reinforced isolation (input to output), ensuring high reliability in demanding applications.
Available with single output voltages of 5, 12, 15, 24, 28, 48, and 54 VDC, this series offers advanced functionalities such as a trim function and remote on/off control. It also complies with EN 50155 (with external circuits), EN 61373 (shock & vibration), and EN 45545-2 (fire & smoke), making it ideal for railway applications.
Enhanced Flexibility & Design Optimization
Optional models include a BUS pin and external UVLO adjustment for greater flexibility:
- The BUS pin helps optimize system design by extending or maintaining holdup time, reducing inrush current, and minimizing capacitor size.
- External UVLO adjustment allows designers to fine-tune the under-voltage lockout point within a specified range.
Exceptional Performance
The CQB150W8 series supports an input voltage range of 9 to 75 VDC, covering key railway power system voltages. With high efficiency of up to 91%, it ensures reliable performance in extreme conditions, operating within a wide case temperature range of -40°C to +105°C. Additionally, it supports high-altitude operation up to 5000m and boasts an MTBF of up to 945k hours.
Comprehensive Protection & Compliance
This series incorporates robust safety features, including:
- Input UVLO (Under-Voltage Lockout)
- Output Over-Current/Over-Voltage Protection
- Over-Temperature Protection
- Continuous Short-Circuit Protection
With certifications such as IEC/UL 62368-1, EN 50155 (with external circuits), and EN 45545-2, the CQB150W8 series meets essential railway safety and performance standards. It also complies with voltage supply interruption Class S3 and voltage change-over Class C2 requirements based on Cincon-referenced circuitry.
