Page 3: Introduction
Another feature of this instrument is its output ON/OFF key. a. For model PS-303DU/305DU, it is only the key to cut off or resume the output as other similar instrument. b. For model PS-2303/2305, it is not only the key to cut off or resume the output, but also be endowed with a new function which its kindred has not. -

5. OPERATION INSTRUCTIONS 5-1. Precaution 1) AC input AC input must be within the range of line voltage ±10%, 50/60Hz. WARNING. To avoid electrical shock, the power cord protective grounding conductor must be connected to ground. 2) Installation Avoid using the supply in a place where the ambient temperature exceeds 40℃. Allow enough space around the power supply for ventilation. -

to the load change. The intersection of constant voltage and constant current modes is called the crossover point. Fig.5-1 shows the relationship between this crossover point and the load. For example, if the load is such that the power supply is operating in the constant voltage mode, a regulated output voltage is provided. -
Page 13: Series Tracking Operation
INDEPENDENT operating mode. Adjust "Voltage" control and "Current" control to the desired output voltage and current. Turn off the power supply and the equipment to be powered during hook-up. Connect the positive polarity of the device being powered to the red (+) terminal of the power supply. Connect the negative polarity of the device being powered to the black (-) terminal of the power supply. -
Page 14: Parallel Tracking Operation
If "single supply" operation is desired, this allows the power supply to be used as twice the voltage and rating current simply by using the negative (black) terminal of the SLAVE supply and the positive (red) terminal of the MASTER supply, the configuration as shown in Fig.5-3. Fig.5-3 Single Supply If the chassis or common of the equipment being powered is separate from both positive and negative polarity power inputs. -
Page 15: Fixed 5V Power Supply Operation
Connect the negative polarity of the device being powered to the black (-) terminal of the MASTER power supply. The configuration is as shown in Fig.5-5. Fig.5-5 Parallel Tracking Operation 5-4-4. Fixed 5V Power Supply Operation The fixed 5V supply provides a 5V DC output with a 3 amp current capacity. The supply is ideal for use with TTL circuits. -
