The adapter card adopts MOS tube to switch on and off to the effectiveness of the switch. The adapter card uses LEDs to display the working voltage of the power supply in real time. The adapter card adopts multi-layer PCB technology to that the PCB board will not be hot when the PCB is in high current. The power synchronization switch is added to realize the function of switching on and off synchronously with the main power supply. Suitable for common server power supplies are DPS-1200FB A, DPS-1200QB A, PS-2751-5Q, PS-2751-LF-1F, HSTSN-PL12, DPS-700LB D, PS-2112-5L, DPS-750RB A Colour: black Material: PCB Size: 92.5x95mm Package Contents: 1 * Breakout Board Only the above package content, other products are not included. Note: Light and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
