Ripple noise are measured at 0MHz of bandwidth by using a " twisted pair-wire terminated with a 0.uf 47uf parallel capacitor.. Tolerance : includes set up tolerance, line regulation and load regulation. 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. For guidance on how to perform these EMC tests, please refer to EMI testing of component power supplies. (as available on 5. Derating may be needed under low input voltages. Please check the derating curve for more details. 6. Length of set up time is measured at first cold start. Turning ON/OFF the power supply may lead to increase of the set up time. 7. No load power consumption<0.8w when ( pin,4) 0 ~ 0.8V or short. 8. When the input voltage is less than 40VAC, the SPS may exhibit degradation of performance. The final product manufacturers must re-confirm this deviation that does not affect basic safety or essential performance.

4 Function Description of Pin No. Function Description AUXG Auxiliary voltage output ground. The signal return is isolated from the output terminals (+V -V). AUX Auxiliary voltage output, 4.75~5.5V, referenced to pin (AUXG). The maximum load current is 0.A. This output has the built-in oring diodes and is not controlled by the "remote ON/OFF control". 4 5 CS Turns the output on and off by electrical or dry contact between pin 4 (), Short: Power OFF, Open: Power ON. Remote control ground. Current sharing signal. When units are connected in parallel, the CS pins of the units should be connected to allow current balance between units. 6,8 GND This pin connects to the negative terminal(-v). Return for DC-OK signal output. 7 DC-OK DC-OK signal is a TTL level signal, referenced to pin8(dc-ok GND). High when PSU turns on. Positive sensing. The signal should be connected to the positive terminal of the load. The and leads should be twisted in pair to minimize noise pick-up effect. The maximum line drop compensation is 0.5V. 0 Negative sensing. The signal should be connected to the negative terminal of the load. The and leads should be twisted in pair to minimize noise pick-up effect. The maximum line drop compensation is 0.5V. Function Manual.Remote Sense The remote sensing compensates voltage drop on the load wiring up to 0.5V.

(,,CS and GND are connected mutually in parallel). ()Difference of output voltages among parallel units should be less than %. ()The total output current must not exceed the value determined by the following equation. (output current at parallel operation)=(rated current per unit) (Number of unit) 0. (4)In parallel operation 4 units is the maximum, please consult the manufacturer for applications of more connecting in parallel. (5)The power supplies should be paralleled using short and large diameter wiring and then connected to the load.
