012-02816C 1/95 $1.00 Instruction Sheet for the PASCO Model SF-9582 12 VOLT AC/DC POWER SUPPLY Introduction scientific PASCO PASCO MODEL SF-9582 AC/DC POWER SUPPLY ON 6 7 8 5 4 9 3 10 2 11 1 OFF 12 VOLTAGE ADJUST AC OUTPUT DC OUTPUT 6 AMPS MAX ➤NOTE: Both AC and DC output circuits are protected with a thermally activated circuit breaker. If at any time the power supply fails to come on, or if it shuts down during operation because of a current overload, press the RESET button on the front panel. This will reset the circuit breaker. Of course, you may have to reduce the voltage or increase the resistance of the load in order to resume operation. RESET 6 AMPS MAX CAUTION RISK OF ELECTRIC SHOCK DO NOT OPEN The PASCO scientific Model SF-9582 12 Volt AC/DC Power Supply provides AC and DC power in 1 volt increments, from 1 to 12 volts, at up to 6 amps. Since the AC and DC power are delivered on separate output connectors, they can be utilized simultaneously. Both outputs are unregulated, and protected from current overload by a thermal circuit breaker. The DC output is full-wave rectified, but unfiltered. To Use the Power Supply: ➀ Plug the power cord into a well-grounded 107-128 VAC, 60 Hz or 198-242 VAC, 50 Hz outlet. (See label on rear of unit). CAUTION: TO PREVENT THE RISK OF ELECTRIC SHOCK, DO NOT REMOVE COVER ON UNIT. NO USER SERVICEABLE PARTS INSIDE. REFER SERVICING TO QUALIFIED SERVICE PERSONNEL. The lightning flash with arrowhead, within an equilateral triangle, is intended to alert the user of the presence of uninsulated “dangerous voltage” within the product’s enclosure that may be of sufficient magnitude to constitute a risk of electric shock to persons. ➁ Connect the appropriate output lines of the power supply to the circuit. (Connecting wires are not provided.) ➂ Set the VOLTAGE ADJUST knob to 1 volt. ➃ Flip the ON/OFF switch on the power supply to ON. The switch will light to show that the power supply is on. The exclamation point within an equilateral triangle is intended to alert the user of the presence of important operating and maintenance (servicing) instructions in the literature accompanying the appliance. ➄ Set the VOLTAGE ADJUST knob to the desired voltage setting (AC values are in RMS units). © 1989 PASCO scientific This instruction sheet edited by: Dave Griffith better 10101 Foothills Blvd. • P.O.

Should this product have to be returned to PASCO scientific, for whatever reason, notify PASCO scientific by letter or phone BEFORE returning the product. Upon notification, the return authorization and shipping instructions will be promptly issued (see reverse side for packing instructions). DC: 1 to 12 volts, unregulated, unfiltered, (full wave rectified), selectable in 1 volt increments; current up to 6 amps. AC and DC outputs are available simultaneously, and both are protected from current overload by a common 6 amp thermally activated circuit breaker. ➤NOTE: NO EQUIPMENT WILL BE ACCEPTED FOR RETURN WITHOUT AN AUTHORIZATION. Total maximum output current is limited to 6 amps. When returning equipment for repair, the units must be packed properly. Carriers will not accept responsibility for damage caused by improper packing. To be certain the unit will not be damaged in shipment, observe the following rules: ➤Caution: AC and DC outputs are not independently floating. Cross-connection could result in internal damage Other PASCO Power Supplies ➀ The carton must be strong enough for the item shipped. PASCO scientific offers a variety of rugged, reliable power supplies. From low-voltage, fixed-output supplies to a 6 KV DC supply, all PASCO power supplies are easy to use, ruggedly built, and short circuit protected for long life in the student lab. For information, check our catalog or call toll-free 1-800-772-8700. ➁ Make certain there are at least two inches of packing material between any point on the apparatus and the inside of the carton. ➂ Make certain that the packing material cannot shift in the carton, or become compressed, thus letting the instrument come in contact with the edge of the carton. Parts List*: Limited Warranty ➤Caution: If repairs are needed, they should be performed only by experienced personnel. REFERENCE PART MDA 3502 D1 4 AMP SLOW F1 THERM FUSE F2 TERMINAL Power 100R R1 R100 R2 NT 15050 T1 PASCO scientific warrants this product to be free from defects in materials and workmanship for a period of one year from the date of shipment to the customer. PASCO will repair or replace, at its option, any part of the product which is deemed to be defective in material or workmanship. This warranty does not cover damage to the product caused by abuse or improper use. Determination of whether a product failure is the result of a manufacturing defect or improper use by the customer shall be made solely by PASCO scientific. Responsibility for the return of equipment for warranty repair belongs to the customer. Equipment must be properly packed to prevent damage and shipped postage or freight prepaid. (Damage caused by improper packing of the equipment for return shipment will not be covered by the warranty.) Shipping costs for returning the equipment after repair will be paid by PASCO scientific. * When ordering parts, be sure to indicate the product number (SF-9582), the part number, and the part description 2 012-02816C 12 Volt AC/DC Power Supply Schematic: 3 12 Volt AC/DC Power Supply 012-02816C Technical Support Feed-Back Contacting Technical Support If you have any comments about this product or this manual please let us know. If you have any suggestions on alternate experiments or find a problem in the manual please tell us. PASCO appreciates any customer feedback. Your input helps us evaluate and improve our product. Before you call the PASCO Technical Support staff it would be helpful to prepare the following information: • If your problem is computer/software related, note: Title and Revision Date of software. Type of Computer (Make, Model, Speed). Type of external Cables/Peripherals. To Reach PASCO • If your problem is with the PASCO apparatus, note: For Technical Support call us at 1-800-772-8700 (tollfree within the U.S.) or (916) 786-3800. Title and Model number (usually listed on the label). Approximate age of apparatus. A detailed description of the problem/sequence of events. (In case you can't call PASCO right away, you won't lose valuable data.) If possible, have the apparatus within reach when calling. This makes descriptions of individual parts much easier. • If your problem relates to the instruction manual, note: Part number and Revision (listed by month and year on the front cover). Have the manual at hand to discuss your questions. 4
