Technical Support

Selecting the right DC-DC converter requires evaluating several key parameters. First, determine your input voltage range and ensure the converter supports your system's voltage with appropriate margin. Next, calculate your output power requirements and select a converter with at least 20% headroom above your maximum load. Consider isolation requirements - medical and industrial applications typically need 3000V isolation or higher. Evaluate efficiency requirements, as higher efficiency reduces heat generation and improves system reliability. Finally, assess package size constraints and operating temperature range. ZLG Power offers comprehensive selection guides and our FAE team can provide personalized recommendations based on your specific application requirements.

Use our online selection tool or contact our FAE team with your input/output voltage, power requirements, and application details for personalized recommendations.

Standard ZLG Power products typically have lead times of 4-6 weeks for production quantities. Popular models like the E_UHB-1W and B_S-1W series are often available from stock with 1-2 week delivery. For high-volume orders or custom specifications, lead times may extend to 8-10 weeks depending on capacity and component availability. We maintain safety stock for commonly used models to support urgent requirements. For critical projects, we recommend placing blanket orders with scheduled releases to ensure continuous supply. Contact our sales team for current lead time information and to discuss scheduling options for your production needs.

Contact sales for current stock availability and lead times. Consider placing forecast orders for critical production schedules.

ZLG Power products purchased through BeiLuo carry a standard 3-year warranty covering manufacturing defects and material failures under normal operating conditions. The warranty covers repair or replacement of defective units at no charge. Extended warranty options are available for critical applications requiring longer coverage periods. Warranty claims require proper documentation of the failure mode and operating conditions. Our technical team assists with failure analysis to determine root cause and warranty eligibility. Products must be operated within specified parameters as outlined in the datasheet. Damage from misuse, overstress, or unauthorized modifications is not covered. Contact our customer service team to initiate warranty claims or inquire about extended coverage options.

Review warranty terms before purchase. Contact customer service for warranty claims or extended coverage inquiries.

Common DC-DC converter issues include output voltage instability, thermal shutdown, and EMI problems. For output issues, verify input voltage is within specified range and check load conditions aren't exceeding ratings. Ensure proper input and output capacitance as recommended in the datasheet. Thermal issues often result from inadequate heat sinking or high ambient temperatures - verify thermal design using the provided thermal models. For EMI problems, review layout guidelines and ensure proper grounding and filtering. Output ripple can often be reduced with additional output capacitance or LC filters. If protection circuits are triggering, investigate for short circuits or overload conditions. Our troubleshooting guides provide systematic diagnostic procedures, and our FAE team is available for complex issue resolution.

Refer to our troubleshooting guides first. Contact FAE support for persistent issues or complex system-level problems.

Yes, BeiLuo works with ZLG Power to develop custom power solutions for specific application requirements. Customization options include modified output voltages, special pin configurations, enhanced isolation ratings, and extended temperature ranges. We can develop fully custom designs for unique form factors or specialized electrical requirements. The customization process begins with a detailed requirements specification including electrical parameters, mechanical constraints, environmental conditions, and qualification standards. Our engineering team evaluates feasibility and develops proposals with timelines and costs. Custom products undergo full qualification testing including environmental, electrical, and reliability verification. Minimum order quantities apply for custom designs. Contact our business development team to discuss your custom power requirements.
