DIMENSION| 110125.2150mm (WHD)
PACKING| 2.47Kg ; 6pcs/15.8Kg/1.55CUFT
NOTE| 1. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25C of ambient temperature.
2. Ripple & noise are measured at 20MHz of bandwidth by using a 12″ twisted pair-ire 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. The final equipment must be re-confirmed that it still meets
EMC directives.
5. Installation clearances: 40mm on top, 20mm on the bottom, 5mm on the left and right side are recommended when loaded permanently with full power.
In case the adjacent device is a heat source, 15mm clearance is recommended.
5. 3 seconds peak power max. and the average output power should not exceed the rate power.
7. Derating may be needed under low input voltage. Please check the derating curve for more details.
3. Consult MEAN WELL for deployment of Radiation class B.
9. The ambient temperature derating of 3.5C/1000m with fanless models and of 5 C/1000m with fan models for operating altitude higher than 2000m(6500ft).

Function Manual

Current sharing
Parallel operation is available by connecting the units shown as below (P+,P- are connected mutually in parallel).
Difference of output voltages among parallel units should be less than 0.2V.
The total output current must not exceed the value determined by the following equation (Output current at parallel operation)=(The rated current per unit) x (Number of unit) x 0.9.
In parallel operation 4 units is the maximum, please consult the manufacture for other applications.
The power supplies should be paralleled using short and large diameter wiring and then connected to the load.
When in parallel operation, the minimum output load should be greater than 5% of total output load. (Min. load >5% rated current per unit x number of unit)
In parallel connection, maybe only one unit (master) operate if the total output load is less than 5% of rated load condition.
The other PSUs (slaves) may go into standby mode and their output LEDs & relays will not turn on.
Some minor noise may be heard at light load condition under parallel operation.
This is a normal phenomenon and the performance of the PSU will not be influenced.
