PRODUCT DETAILS & SHOWCASE
📋 Technical Application Notes
- Inductive Loads: For coils, magnetic valves, and motors, we recommend a power supply 3-5 times the rated power of the load.
- Safety First: Isolated products are the safest. They prevent high input voltage from passing directly to the output end, protecting precious equipment.
- Installation: Isolated products' negative poles (ground) cannot be shared; input and output negative poles must be used separately.
- Protection: Most buck-boost products include overcurrent, short-circuit, undervoltage, and overheating protection as standard.
- Customization: Isolated power supply production involves transformer remaking and circuit adjustment. Prototype delivery periods may be extended.
Frequently Asked Questions (FAQ)
What is the advantage of an isolated DC-DC converter?
Isolation provides an electrical barrier that protects the output load from input voltage spikes and noise, ensuring higher safety for sensitive electronic systems.
Can I share the negative pole between input and output?
No, for isolated products, the negative poles must remain separate. Sharing the ground will cause the isolation effect to be lost.
What should I consider for motor or inductive applications?
Inductive loads have high start-up currents. It is recommended to choose a converter with a rated power 3 to 5 times higher than the load's continuous power.
Are these converters waterproof?
Yes, models with hard gel encapsulation are waterproof and suitable for harsh outdoor environments. However, note that encapsulated models generally cannot be repaired.
What protection features are built-in?
Most of our isolated converters include output overcurrent, short-circuit protection, input undervoltage protection, and thermal shutdown.
Can the output voltage be customized?
Yes, we specialize in customization. We can adjust input/output voltage and current settings to meet your specific project needs.
