1, switching power supply metal shell power supply shell is generally connected with the ground (FG), to be reliably grounded, to ensure safety, can not be mistakenly connected to the shell on the zero line;
2. Before the installation of switching power supply is completed and powered for trial use, please check and proofread the connection on the terminals again, and make sure that the input and output, AC and DC, single-phase and multi-phase, positive and negative, voltage and current values are correct, and can be powered on.
3, for high-power switching power supply, there are generally two or more than two “+” output terminals “-” “output terminals, in fact, they belong to an output electrode, just for the convenience of users wiring, and the multiple terminals respectively in the internal and connected together;4. In order to achieve full heat dissipation, the general switching power supply should be installed in the position of better air convection conditions, or installed on the chassis shell through the shell to transmit the heat outdoors;
5. Switching power supply is tested with resistive load before delivery. If it needs to be used in capacitive or inductive load, it should be explained in the order contract in advance.
6, for double switching power supply output symmetrical load, the preferred symmetric output power supply;

1. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25℃ 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. Line regulation is measured from low line to high line at rated load. 5. Load regulation is measured from 0% to 100% rated load. 6. The power supply is considered a component which will be installed into a final equipment. The final equipment must be re-confirmed that it still meets EMC directives. |
