Technical Application Description
  1. All buck-boost and step-up/step-down products come standard with output overcurrent protection, output short-circuit protection, input undervoltage protection, and chip overheating protection (large power supplies feature over-temperature protection on the circuit board or casing, generally triggering around 90°C).
  2. Due to circuit structure limitations, step-up series products do not have output short-circuit protection or an automatic shutdown function under input undervoltage. When installing, add appropriate fuses at the input side to prevent high currents from damaging the power source during a short circuit.
  3. The gold-colored aluminum casing models feature high-temperature resistance and high reliability, making them suitable for outdoor and heavy-duty applications.
  4. All products with hard gel encapsulation cannot be repaired (except for the extra-large 500W aluminum shell models) and can only be treated with replacement. Verify usage parameters prior to ordering.
  5. To prevent short circuits from burning equipment, add external fuses; to prevent current backflow and reverse connection, add diodes; to prevent overvoltage direct-pass, add overvoltage protection circuits.
  6. For inductive loads (coils, magnetic valves, speakers) and motor applications, we recommend choosing a power supply with a rating 3 to 5 times the continuous power consumption of the load.
  7. When driving a single light bulb, a constant current power supply is recommended. For battery charging, select products featuring dedicated charging controllers. For motors, use motor-specific models. For parallel operations, choose units with active current sharing.
  8. The primary failure mode of a non-isolated buck power supply is that high input voltage can directly pass to the output end if the internal switch fails. This may destroy precious output loads. For critical devices, we strongly recommend isolated converters.
  9. The critical failure mode of a non-isolated boost converter is that a short circuit at the output side draws high input current directly, which can burn out wires. Adding a correctly rated fuse at the input prevents this. Isolated boost setups are generally not needed.
  10. A non-isolated buck-boost converter shares the failure risks of both buck and boost Topologies. When powering valuable loads, we highly recommend isolated buck-boost models.
  11. The negative pole (ground) of isolated converters cannot be commoned. The input negative and output negative must be kept separate; connecting them bypasses the isolation barrier.
  12. For setups where the input voltage is three times (or more) the output voltage, we strongly recommend isolated converters to improve overall system safety.
  13. Isolated power supplies generally support a narrower input voltage range and have a smaller output adjustment range compared to non-isolated power supplies.
  14. Isolated power supplies can support negative voltage input, with the output configured to be either positive or negative. For negative voltage inputs, connect the 0V line to the red wire, and the negative line to the black wire.
  15. Prototype and custom runs for isolated supplies require winding new transformers and adjusting circuit parameters. This differs from non-isolated designs which can be modified simply by scaling a voltage regulator. Plan for longer lead times on custom orders.
  16. Because isolated power supplies prevent high-voltage input lines from directly contacting the output side in the event of component failure, they are highly secure. More than 90% of global power conversion designs utilize isolated layouts.

Frequently Asked Questions (FAQ)
What is the advantage of using an isolated DC-DC converter over a non-isolated converter?
An isolated converter features complete electrical isolation between its input and output terminals. This configuration prevents input surges or high voltages from passing straight through to your output loads in the event of an internal failure. It also breaks ground loops and stops electrical noise from transferring between circuits.
Why does my step-up (boost) converter require an external fuse?
Due to the circuit design of step-up topologies, they lack short-circuit and undervoltage shutdown protection on the output side. An external input fuse is required to protect the input supply and wiring from excessive current draw in the event of an output short circuit.
How should I select a converter for inductive loads or motor applications?
For inductive loads such as solenoid coils, magnetic valves, speakers, or electric motors, choose a power supply rated at 3 to 5 times the continuous power of the load. This headroom handles high inductive startup currents without triggering overload protections.
Can I share the input and output ground (negative pole) in an isolated system?
No. The negative poles (grounds) of the input and output must remain completely separate. Connecting them together bridges the isolation barrier, nullifying the safety and noise-prevention benefits of the isolation transformer.
How do I wire an isolated converter for a negative voltage input?
Isolated converters support negative voltage input configurations. Connect your 0V reference line to the red wire (input positive) and connect the negative voltage source line to the black wire (input negative).
What safety protections are built into these converters?
All our standard buck-boost and step-up/step-down converters are equipped with output overcurrent protection, output short-circuit protection, input undervoltage protection, and chip thermal shutdown. Larger power converters also feature integrated temperature sensors on the PCB or casing that trigger safety shutdowns around 90°C.
