| NOTE | 1. All parameters NOT specialy mentoned are measured at normal input (B:24Vdc, C:48VdC, D:110VGC), rated ioad 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 jef & 47 uf paralel capacitor. . lolerance: includes set up tolerance, line regulation and load regulaton. Derating may be needed under low input voltage. Please check the derating curve for more details. .3 seconds max., please reler to peak loading curves. . 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) 7.

- Current sharing
- Parallel operation is available by connecting the units shown as below (P+,P- are connected mutually in parallel) :
- The voltage difference among each output should be minimized that less than 0.2V is required.
- 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.
- 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)
- Remote ON-OFF Control
※ The power supply can be turned ON-OFF by using the “Remote ON-OFF” function.
| Remote ON-OFF (TB1 PIN2,4) | Output Status |
| Open or 4 ~ 10VDC | power supply ON |
| Short or 0 ~ 0.8VDC | power supply OFF |
Input face
There is one fuse connected in series to the positive input line, which is used to protect against abnormal surge. Fuse specifications of each
model are shown as below.
| Type | Fuse Type | Reference and Rating |
| B | Time-Lag | Conquer MST, 10A, 250V *2 |
| C | Time-Lag | Conquer MST, 6.3A, 250V *2 |
| D | Time-Lag | Conquer MST, 6.3A, 250V *1 |
Input Under-Voltage Protection
If input voltage drops below Vimin, the internal control IC shuts down and there is no output voltage. It recovers automatically when input
voltage reaches above Vimin,please refer to the cruve below.
Input Reverse Polarity Protection
There is a MOSFET connected 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 MOSFET to reduce power
consumption after accomplishing the start-up.
Hold-up Time
EN50155: 2007 version – B/C- type comply with S2 level (10ms)@ 70% load ; D-type comply with S2 level (10ms)@ full load, Please refer to the table and curves show below for the hold up time specification.
