Using the methods and precautions

1. Check before electrify: After switching the power supply is preceded checking storage and transport after transport if there is damage, such as loose screws, whether the abnormal appearance, before and after the power cord output terminals are falling and damp, etc., if the above situation promptly.

2. wiring: connect the ground wire and secure input and output power cord after confirming the connection is correct, only work after the joint firm.

3.no-load electricity: turn on the power switch, adjust the potentiometer constant pressure on the panel, then the voltmeter on the panel should be based on your adjusted and until you produce a corresponding change in the required voltage value.

4.adjust the output steady flow value: Ze press labeled panel connected between the output and the load connected to the wire, (note wire cross-sectional area should be large enough), and confirmed its constant after the load is connected firmly adjusted on the panel flow potentiometer to your desired steady flow value (note that only a small current circumstances it is possible to use this feature) General Keep constant potentiometer clockwise to maximum, otherwise it will cause the output power can not be loaded, because it makes in limiting state power.

5. the working environment: Do not use because Tun source load when work is people internally generated heat, if this time the outside temperature is too high will result in reduced efficiency of the power supply, and in severe ambient temperature higher than 39 degrees in the place even damaged or automatically shut down. (Recommended at room temperature)

6. Fan: fan of the power right then, please do not block the air inlet and outlet at work, you should leave enough space so that the heat of the fuselage. The machine fan with intelligent circuit control, only the internal chassis temperature exceeds 45 ° C fan will start their own, whereas less than 45 ° C will automatically stop.

7. Protection: input overvoltage, undervoltage, lightning, output overvoltage, overcurrent short circuit, overheating foregoing the opportunity to automatically turn on protection against equipment damage. In general protection status indicator will light green (note constant state of exception) will automatically cut off power serious.

8. Safety: non-professionals, do not open their own cover, or the internal circuit board, because there are high-voltage lines inside for a long time, so as not to inflict damage!
