the over-temperature protection may take effect, depending on the input voltage and output power. A brushless fan is used to cool the power supply by drawing cool air through the two sides and exhausting the heat through the fan outlet on the rear panel. Sufficient space must be left at the rear and two sides of the cabinet for air circulation when the power supply is installed. -
Page 14: Chapter 2 Initial Operation
Chapter 2 Initial Operation Initial Operation This chapter mainly focuses on three basic tests which should be performed before the operation of the power supply: the preliminary checkout, the power-on checkout, and the output checkout. The preliminary checkout is to check if the power supply could run correctly. -
Page 15: Fuse Replacement
Fuse Replacement 1 Replace the fuse Step 1: Remove the fuse-holder below AC power inlet. Step 2: Replace the fuse with what meets the requirements. Step 3: Put back the fuse holder. For 180V-265V AC operation, 10AT fuse is used. -
Page 16: Power-On Checkout
Power-On Checkout The power-on test includes an automatic self-test that checks the internal microprocessors and a system self-test after the power supply is turned on, and examines the information relate to self-test process shown on the front panel. You will observe the following sequence on the display: 1. -
Page 17: Output Checkout
Output Checkout The output checkout is to ensure that the power supply develops its rated outputs and properly responds to various operations. Specific steps are shown as followings: Voltage Output Checkout 1. Turn on the power supply. Press the “Power-on” button, and finish the power-on checkout. Usually the power supply will go into the power-on / reset state automatically. -
Page 18: Current Output Checkout
Current Output Checkout 1. Turn on the power supply. Press “Power-on” button and finish the power-on checkout. Usually the power supply will go into the power-on / reset state automatically and the “OFF” annunciator in the lower right corner of the LCD turns on. Both the voltage value and current value are 0. - Page 19 6. Ensure that the current can be adjusted from 0A to the maximum rated value. Adjust the current value to 0A and then gradually to the maximum rated value with the knobs or keys. If an error has been detected during the output checkout procedures, the ERROR annunciator will turn on.

resistance value (compared to RC), the output voltage is at the voltage setting, and the output current is less than the current setting. In this case the power supply is in the constant-voltage (CV) mode and the current setting acts as a current limit. When the load RL is less than RC, the output current will dominate since the voltage will be less than the set voltage. -

current flow multiplied by the impedance. To minimize this effect, the output terminal can be grounded at the output terminal. Alternately, any impedance to earth ground should have a complementary impedance to earth ground to cancel generated voltages. Connecting the Load Output Isolation The output of the power supply is isolated from earth ground and the power supply can be connected to the ground with the earth ground terminal when needed. -
Page 62: Inductive Load
with large capacitor may cause ringing in the power supply’s transient response. It is possible that certain combinations of load will result in output instability. And the problem may be solved by properly decreasing the total load capacitance. A large capacitor at the output terminals may cause the power supply to cross into CC or unregulated mode momentarily when the output is enabled. -

The lower the temperature of the components, the better the reliability. When the power supply is in operation, an internal fan installed in the rear of power supply can keep the temperature of components low. -
