YY-CVP-250 Series

Date: 2022-09-15

The use of Cool MOSFETs significantly improves conversion efficiency and reduces the product's temperature.

Replacing Schottky diodes with MOSFETs leverages the low-resistance state of MOSFETs, greatly enhancing efficiency, reducing losses and heat generation, and extending the power supply's lifespan.

Intelligent temperature management enters hiccup mode when the temperature exceeds a set threshold.

It provides overcurrent protection, over-temperature protection, overvoltage protection, and short-circuit protection.

Packing List
YY-CVP-250

01 Advantageous

      It uses a well-known domestic low internal resistance Cool MOSFET, featuring low heat generation and excellent switching performance.

YY-CVP-250

YY-CVP-250

02 Advantageous

      It provides overvoltage protection, overcurrent protection, short-circuit protection, and overload protection. When any protection mechanism is triggered, the power supply automatically shuts down, and after the fault is resolved, the power supply resumes operation.

03 Advantageous

      All products undergo full-load aging test in a high-temperature aging machine, with the enviroment temperature set to 60°C.
