Frequently Asked Questions for 4.5A DC Power Supplies
Q: How does the 0-4.5A current limit protect connected test circuits?
These regulated power supplies allow precision multi-turn encoder or digital keypad current setting from 0A to 4.5A. If the load resistance drops or a short occurs, the unit instantly clamps into Constant Current (CC) mode, preventing thermal runaway or DUT destruction.
Q: Are high-current output terminals safe for continuous operation at 4.5A?
Yes. Models equipped with high output currents use heavy-duty solid brass or pure copper busbar terminal blocks engineered to handle continuous full-load currents with minimal temperature rise and contact resistance.
Q: How are shipping and warranty handled for these 4.5A units?
All units undergo 100% full-load burn-in in thermal aging chambers prior to dispatch. We ship worldwide via DDP door-to-door air express (approx. 10 business days to US/Europe) and back every unit with a 1-year hardware warranty.
