## **PS ON/OFF REMOTE CONTROL AND FAN CONTROL** 

The PS-ON remote control is provided in CN3 pin 4. The diagram and control function are shown as follow: Power ON: VPS-ON ≤ 2 V, IPS-ON ≥ 10 mA (PS-ON and GND short, IPS-ON = 10 mA typical) Power OFF: Open circuit, VPS-ON = 4V 

## **Figure 1** 

The fan control is provided in CN3 pin 3. The control function and diagram are shown as follow: Fan ON: VFAN-EN ≥ 1 V 

Fan OFF: Open circuit, VFAN-EN = 0 

## **Figure 2** 

When the PS-ON remote control function is not used,connect a short circuit between the pin PS-ON and FAN-EN. 

**Figure 3** 

Note:    Product is supplied with remote control and fan control disabled via a jumper between PS-ON and FAN-EN (see Figure 3). To use these functions remove jumper and refer to Figures 1 and 2.

## **PARALLEL CONTROL AND CURRENT SHARING** 

The optional PC pin may be used to connect multiple power supplies in parallel for current sharing (see Figure 4). For proper operation, only power supplies with the same output voltage should be connected in parallel[1] , the total output power should be limited to 90% of the total rated power[2] , and the remote sensing feature should not be utilized[3] . For reliable operation, it is also suggested that the remote on/off feature be used to synchronize the outputs during turn on and turn off. 

## **Figure 4 Connection diagram for parallel operation and current sharing** 

Notes:    1. Output voltage of all power supplies should be within 0.2 V of each other at no load. 

- ii  2. Total output power ≤ Po,rated x N x 0.9. 

- ii  3. Leave +Sense and -Sense pins open when current sharing. 

ii  4. It is recommended to use the PS-ON pin to enable/disable the power supplies output when current sharing. See Figure 4.
