Introduction
MORNSUN URF1D_FB-400(H)WR3 series is a high-performance DC/DC converter specialized for railway applications. The product features 400W output power without minimum load requirement, a wide input voltage of 66-160VDC, and allowing operating temperature of up to 100℃.
It has input under-voltage, output over-current, over-voltage, short-circuit, and over-temperature protections, and the functions of remote On/Off control, remote sense compensation, and output voltage trim adjustment. This series is designed to meet IEC/EN/UL62368/EN50155 standards and adopt vacuum potting technology to improve the product’s reliability.
Advantages
1. Wide operating temperature range for harsh environment
The ambient temperature outside the vehicle usually ranges from -40℃ to +50℃, and the temperature of the internal PCB board can even reach -40℃ to +85℃. Power supplies with a wider operating temperature range are needed to meet the actual use requirements.
URF1D_FB-400(H)WR3 series has a wide operating temperature range from -40℃ to +100℃, with an excellent temperature derating curve, and low component heat, significantly improving product lifespan and reliability.
2. 3000VAC Reinforced insulation to meet high safety requirements
Railway EN50155 standard has high safety requirements, such as the maximum insulation input-output voltage of 1500VAC, and also strict requirements for EMC, shock and vibration, extreme temperature, high humidity, etc. The URF1D_FB-400(H)WR3 series has reinforced insulation with an input-output voltage of 3000VAC, input-case voltage of 2100VAC and output-case voltage of 1500VAC. The design complies with safety design requirements and meets the requirements of the railway industry power standard.
3. Vacuum Potting technology improves reliability
The vast majority of electronic devices are hung on the vehicle body or placed in the vehicle box, which must meet the requirements of vibration Class I Level B.
The URF1D_FB-400(H)WR3 series adopts vacuum potting technology, which can strengthen the immunity to external impact and vibration. On the other hand, the vacuum potting technology makes the components and wires avoid exposure to the air, improves the insulation, and further improves product reliability.
Applications
URF1D_FB-400(H)WR3 can be widely used in railway systems and related equipment, such as roadside signal light, environmental monitoring system, battery system and LED control system,etc.
