NOTE

| 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 20M of bandwidth by using a 12 twisted pair-wire terminated with a 0.1μf & 47μf 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℃/1000m with fanless models and of 5℃/1000m with fan models for operating altitude higher than2000m(6500ft).

7. 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.

Function Manual

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 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
When in parallel operation, the minimum output load should be greater than 3% of total output (Min. load > 3% rated current per unit x number of unit)

1. 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 abnormal surge. Fuse specifications of each model are shown as 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 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 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 comply with S2 level (10ms) @ full load , please refer to the table and curves show below for the hold up time specification.
