POWER SUPPLY MODEL XP-800 TWO AC VARIABLE VOLTAGES; 0-120V and 0-40V @ 7A, PLUS 0-28VDC @ UP TO 10A Instruction Manual Elenco Electronics, Inc. Copyright © 1991 Elenco Electronics, Inc. Revised 2002 REV-I 753206 INTRODUCTION The XP-800 contains three output voltages: 0 to 28VDC, 0 to 40VAC and 0 to 120VAC. The maximum current from the 28VAC supply is 10 amps. At 10 amp load current, the maximum attainable voltage is 20VDC. The maximum current from the 40VAC supply is 7 amps. At 5 amp load current, the maximum voltage attainable is 38VAC. The maximum current from the 120VAC supply is 2 amps. A 10 amp circuit breaker on the back panel protects the 28VDC supply. A 3 amp circuit breaker on the back panel protects the 120VAC supply. This circuit breaker also protects the 40VAC supply by limiting the current to the power transformer. In addition, the XP-800 contains a 5 amp fuse on the AC input. This fuse is located on the back panel. All three supplies are controlled by the Voltage Adjust knob on the front panel. The unit contains two digital meters to simultaneously display the voltage and current of any supply. Which supply is displayed is controlled by a knob on the front panel. This knob selects only which output is displayed. All three supply voltages are present at all times. SAFETY PRECAUTIONS CAUTION: When removing cover, always disconnect the power cord from the AC socket. Service repair should be done by qualified personnel who are knowledgeable of electrical hazards. Certain safety precautions must be observed when this power supply is used with external circuits that are connected to AC power lines. There is always some danger when working with electrical equipment or circuits that operate at hazardous voltages. You should thoroughly familiarize yourself with the equipment before working on it. High voltages may appear at unexpected points in defective equipment. The XP-800 is equipped with a three wire line cord which grounds the chassis to the power line ground. DO NOT CUT OFF OR DISABLE THE GROUND PLUG. The 28VDC and 40VAC circuits are isolated from the AC input via the power transformer. When working with other equipment, this may not be the case. Always be familiar with the equipment rating. Keep in mind that defective equipment can have dangerous voltages at unexpected places.
