PACKING

1. All parameters NOT specially mentioned are measured at normal input (B:24Vdc , C:48Vdc , D:110Vdc ) , 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 0.1 f & 47 f parallel capacitor.μμ

3. Tolerance : includes set up tolerance, line regulation and load regulation.

4. Derating may be needed under low input voltage. Please check the derating curve for more details.

NOTE

5. 3 seconds max., please refer to peak loading curves.

6. The power supply is considered as an independent unit, but the final equipment still need to re-confirm that the whole system complies with
the EMC directives. 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)

Function Manual

1. Current sharing

(1) Parallel operation is available by connecting the units shown as below (P+,P- are connected mutually in parallel) :
(2) The voltage difference among each output should be minimized that less than 0.2V is required.
(3) 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.
(4) In parallel operation 4 units is the maximum, please consult the manufacture for other applications.
(5) When in parallel operation, the minimum output load should be greater than 3% of total output load.

(Min. load > 3% rated current per unit x number of unit)

Input Reverse Polarity Protection

There is a MOSFETconnected in series to the negative input line. If the input polarity is connected reversely, the MOSFET opens and

there will be no output to protect the unit.

Inrush Current

Inrush current is suppressed by a resistor during the initial start-up, and then the resistor is bypassed by a MOSFETto reduce power

consumption after accomplishing the start-up.
