**NOTE**| 1. All parameters NOT specially mentioned are measured at normal input (B:24Vdc, C:48Vdc, D:110Vdc ), rated load, and 25C 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. Derating may be needed under low input voltage. Please check the derating curve for more details.
5. 150% 5 seconds, please refer to peak loading curves.
6. The ambient temperature derating of 3.5 C/1000m with fanless models and of 5 C/100Om with fan models for operating altitude higher than2000m(6500ft).
7. The power supply is considered an independent unit, but the final equipment still needs 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

Current sharing

Parallel operation is available by connecting the units shown below (P+, and P- are connected mutually in parallel) :
The voltage difference among each output should be minimized so 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 units) x 0.9.
In parallel operation 4 units are the maximum, please consult the manufacturer for other applications.
When in parallel operation, the minimum output load should be greater than 3% of the 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 5.5 ~ 10VDC	power supply ON
Short or 0 ~ 0.8VDC	power supply OFF

Input Fuse

There is one fuse connected in series to the positive input line, which is used to protect against the abnormal surge. The fuse specifications of each model are shown below.

Type	Fuse Type	Reference and Rating
B	Time-Lag	Conquer MST, 10A, 250V *5
C	Time-Lag	Conquer MST, 8A, 250V *3
D	Time-Lag	Conquer MST, 6.3A, 250V *2

Input Under-Voltage Protection
If the input voltage drops below Vimin, the internal control IC shuts down and there is no output voltage. It recovers automatically when the input voltage reaches above Vimin, please refer to the curve below.

Input Reverse Polarity Protection
There are two MOSFETs connected in series to the negative input line. If the input polarity is connected reversely, the MOSFETs open 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 MOSFETs to reduce power consumption after accomplishing the start-up.

Hold-up Time

EN50155:2017 version- B/C/D type complies with S2 level (10ms) @ full load, please refer to the table and curves shown below for the hold-up time specification.
