demolition of short circuit conductor. Adjust the voltage to the desired voltage

value, connects the load to the output very eight straight, the negative 10 (pay

attention to the positive and negative polarity correctly), can be normal use,

steady flow indicator lights up 5 at this time. Work in steady flow state power,

i.e., constant current, voltage changes over load.

（5）Note: please do not load to start the power switch, otherwise easy to

damage the power supply box of load. Connect the load to the output terminals

"+" "-", pay attention to the positive and negative polarity is correct. When

requiring higher ripple coefficient, please ensure that the "+" "-" output

terminals must have a reliable grounding "GND", in order to reduce the ripple

四、Maintain

4-1 Insurance tube replacement

If there are any insurance tube burn out, you must find out the reason, the

native of insurance available capacity of the same failure tube replaced.

4-2 Maintain

The power supply before delivery by the precision calibration,

non-professional workers do not open the without authorization. If you have

internal damage, please contact with dealers, high pressure machine, please do

not repair yourself.

Thank you for purchasing use hard switching power supply series products.

In order to make you better use this product, please read the instructions

carefully before use, and properly kept.

一、Summarize

LW series power supply for high efficiency switching power supply, it has

the load capability is strong, continuous working failure rate is low, and had a

warm, overload, current limiting and various protective functions. Can be

regulated power supply using also can be used for current, voltage regulator,

steady flow can be automatic conversion. Is a research, colleges and

universities, the factory products such as the preferred power. Specific model

parameters are shown in table 1.
