How to choose our power supply?                                                                                                       

1. Single output

To determine the power after the output voltage is decided. The power range of our switching power supply is 10W to 1500W, output voltage from 3V to 220V DC. If the requirement is 24V, 1A, we can choose S-25-24, and within cost range, retain 10% -20% of the power allowance.

2. Multi-output

The multi-output power supply has the main and secondary circuit output. The character of main circuit output is better than the secondary.To ensure the load regulation and so on, every circuit has to be with a certain load. If just using the second circuit, the main circuit has to be matched with corresponding dummy load (more than 0.5A or larger)

3. Before placing an order, please kindly confirm us the details below: Input voltage, Output voltage, Output current, Power,waterproof or not, special size or not, and other special requests.

4. When purchasing the power supply, the customer should know the operation environment, for example, temperature, humidity, altitude, etc.

How to use our power supply?                                                                                                                       

1. Before using the power supply, make sure whether the input voltage specification is in accordance with the input voltage nominal value of the power supply to use. Generally, the switches are located at220V, please note that when using.

2. Wiring in strict accordance with the drawings.

3. Please note whether the input line and output could meet the power requirement.

4. Waterproof issue of switching power supply

In general, the base plate switch power supply is not waterproof. If the power supply is installed outdoors, please equip it with waterproof case.

How to installation our power supply?                                                                                                   

Please use the proper screw to fix the power supply in the applicable environment, the screw length should be less than 6mm, cannot reach to the circuit boards, to avoid touching the internal components and conductive dangerous.

There should be ventilation channels or exhaust devices in the power supply working space. In order to ensure the use security and avoid reduce the interference; please make sure that earth the ground wire well. The ground wire is large than AWG#.

After installation, please measure the insulation resistance of shell between input and output, to avoid electric shock.

Questions for our power supply?                                                                                                                

1. When using your power supply, find the shell with voltage, is that normal?

Answer: That is normal. According to the EMI request, the input port and the shell are connected by a capacitor, which causes the voltage on the shell. It’s specified in the IEC standard that the leakage current is less than 3.5mA. It’s safe and won't cause any damage to people.

2. When needing 24V voltage, but only 12V power supply at hand, can this work to connect 2 pieces 12W power supply in series?

Answer: It’s workable. We can cut down the cost through that way sometimes.

3. Can use S-50W power supply as the charging power supply?

 Answer: Yes. But in order to avoid battery feedback, please be advised use a series diode on the output, and pay attention to the diode heat dissipation.

4. Why the power supply fails to boot correctly?

 Answer: When the load is electric, light bulbs or capacitive load, the instantaneous electric current is excessive when booting, it can cause overload protection. In this case, please choose the appropriate power or contact the manufacture factory.
