RIPPLE & NOISE (max.) Note.2
VOLTAGE TOLERANCE Note.3
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 0.1uf & 47uf parallel capacitor.
3. 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. All the EMC tests are been executed by mounting the unit on
a mm* mm metal plate with 1mm of thickness. The final equipment must be re-confirmed that it still meets EMC directives.360 360 For guidance on how to
perform these EMC tests, please refer to EMI testing of component power supplies. (as available on http://www.meanwell.com)
5. Derating may be needed under low input voltages. Please check the derating curve for more details.
6. The ambient temperature derating of 3.5 /1000m with fanless models and of 5 /1000m with fan models for operating altitude higher than 2000m(6500ft).℃℃

DC-OK
Turns the output on and off by electrical or dry contact between pin 4 ( RC+) and pin 3 (RC-). 0~0.8V: Power ON, 4~10V: Power OFF.
DC-OK signal is a TTL level signal, referenced to pin6(DC-OK GND). High when PSU turns on.
Negative sensing. The -S signal should be connected to the negative terminal of the load. The -S and +S leads should be twisted in pair to
minimize noise pick-up effect. The maximum line drop compensation is 0.5V.
Current sharing signal. When units are connected in parallel, the CS pins of the units must be connected to allow current balance
between units.

4.Current Sharing with Remote Sensing (Optional for 24V & 48V)
USP-500 has the built-in active current sharing function and can be connected in parallel to provide higher output power :
(1)Parallel operation is available by connecting the units shown as below.
(2)Difference of output voltages among parallel units should be less than 2%.
(3)The total output current must not exceed the value determined by the following equation.
(4)In parallel operation 2 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.
(+S,-S,CS and GND are connected mutually in parallel).
