1.All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25℃ of ambient temperature. 2.Ripple & noise are measured at 20MHz of bandwidth by using a 12” twisted pair-wire terminated with a 0.1μ & 47μ parallel capacitor. 3.Each output can within current range. But total output power can’t exceed rated load. 4.The power supply is considered a component which will be installed into a final equipment. The final equipment must be re-confirmed that it still meets EMC directives. | ||||||||||||
Quad output design: Four channels meet diverse power needs, eliminating the need for multiple single-output power supplies and saving space.
High efficiency: Up to 80% efficiency reduces energy loss, making it more cost-effective than lower-efficiency alternatives.
Switchable AC input: Adapts to 88~132VAC or 176~264VAC via switch, suitable for global use without extra adapters.
Comprehensive protection: Shuts down output during overloading (105%~135%) or overvoltage (115%~135%), with recovery via re-powering, protecting connected devices better than unprotected models.
Rigorous testing: 100% full load burn-in test ensures the power supply works reliably under heavy use, giving users confidence in its performance.
Stable frequency: Fixed 25KHz switching frequency minimizes interference, crucial for sensitive electronics compared to variable-frequency power supplies.
Durable build: Withstands vibration (10~500Hz, 2G) and operates in -10℃~+60℃, ensuring longevity in tough environments.
Constructed with high-quality components, it maintains stable output with ripple & noise as low as 80mVp-p. The isolation resistance of 100M Ohms/500VDC and withstand voltage of 3KVAC (I/P-O/P) ensure safe operation, while the wide working temperature range guarantees performance in various conditions.

Q: What’s the maximum total power the Q-120 series can provide?
A: Q-120D has the highest rated power at 124W, but total output can’t exceed the rated load.
Q: Can all four outputs be used at their maximum current simultaneously?
A: Each output works within its current range, but total power must not exceed the rated load.
Q: How does the overvoltage protection work?
A: It shuts down the output when voltage reaches 115%~135% of CH1’s rated voltage, and recovers after re-powering.
