HSN-300 Series
300W Single Output Switching Power Supply
MEAN WELL HSN-300 Series is a 300W Single Output Switching Power Supply. The series features a ultra low profile (31mm height) and slim design (81mm width), making the power supply ideal for sign panel applications. Two input models are available, 90~132VAC and 180~264VAC. Output voltage provides either 4.2V or 5V. Allowing the HSN-300 series to be used with both old and new generations of sign panel driver ICs. The devices operate at -20ºC to +70ºC with free air convection cooling. Applications include indoor and outdoor LED electronic signage, LED moving signs, and LED TV walls.
Installation (HSN-300) :
1.Operate with additional aluminum plate :
In order to meet the“Derating Curve”and the “Static Characteristics” ,HSN-300 series must be installed onto an aluminum plate(or the cabinet of the same size) on the bottom.The size of the suggested aluminum plate is shown as below. And for optimizing thermal performance, the aluminum plate must have an even and smooth surface (or coated with thermal grease), and HSN series must be firmly mounted at the center of the aluminum plate.
2.For heat dissipation :
At least 5cm installation distance around the PSU should be kept.
Applications :
- Indoor and outdoor LED electronic signage
- moving signs (LED)
- TV walls (LED )
