Technical Parameters

Our engineer designed the high power supply 2000W, there are two models, one model is the open frame SMPS, another model is enclosed PSU with cooling fan. Both of the two models are very popular among the market.

Features:

1, High efficiency 2000W 48V switching power supply;

2, Built-in EMI filter and PFC function, low noise, high reliability;

3, 48V power supply with wide range of AC input voltage;

4, 2000W power supply with overload, short circuit, over-voltage and over temperature protection;

5, This power supply used in LED lighting and general electronic products.

FAQ:

Q1: When the AC is connected, the power supply start to work together with the cooling fan?

A1: YES, It is.

Q2: If i don't want the power supply cooling fan work together with the high power supply, how do you make it?

A2: We can control the cooling fan by the power supply temperature, when the PSU temperature is more than 45℃, the cooling fan will start to work.

Q3: When the AC is connected, the power supply start to work together with the cooling fan?

A3: YES, It is.

Q4: If i don't want the power supply cooling fan work together with the high power supply, how do you make it?

A4: We can control the cooling fan by the power supply temperature, when the PSU temperature is more than 45℃, the cooling fan will start to work.
