Page 11: Operation Instructions
OPERATION INSTRUCTIONS Precaution AC input AC input should be within the range of line voltage 10% 50160Hz 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 ambient temperature exceeds 40°C. The heat sink located at the rear of the supply must have sufficient air space for radiation. - Page 12 Vo Max -Crossover Point Output Voltage Output Current Fig. 5-1 Constant VoltageIConstant Current Characteristic. A good example of this would be seen when charging a 12-volt battery. Initially, the open circuit voltage of the power supply may be preset for 13.8 volts. A low battery will place a heavy load on the supply and it will operate in the constant current mode, which may be adjusted for a 1 amp charging rate.

MAINTENANCE The following instructions.are for use by qualified personnel only. To avoid electrical shock, do not perform any servicing other than contained in the operating instructions unless you are qualified to do so. Fuse Replacement If the fuse blows, the C V or C C indicators will not light and the power supply will not operate. The fuse should not normally open unless a problem has developed in the unit. -
