SAFETY SUMMARY
This power source contains high voltage and current circuits which are potentially lethal.
Because of its size and weight, mechanical stability must be ensured. The following safety
guidelines must be followed when operating or servicing this equipment. These guidelines
are not a substitute for vigilance and common sense. California Instruments assumes no
liability for the customer's failure to comply with these requirements.
APPLYING POWER AND GROUNDING
Verify the correct voltage is applied to the unit (100 to 240 VAC Nominal). Verify that the input
power cord is plugged into a properly grounded utility outlet.
FUSES
Use only fuses of the specified current, voltage, and protection speed.
Do not short out the fuse holder or use a repaired fuse.
The 801P/1001P units use a North American ferrule type fuse rated at 15A and 250Volts. (Fast Acting)
The 1251P unit uses a North American ferrule type fuse rated at 20A and 250Volts. (Fast Acting)
DO NOT OPERATE IN A VOLATILE ATMOSPHERE
Do not operate the power source in the presence of flammable gases or fumes.
DO NOT TOUCH ENERGIZED CIRCUITS
Disconnect the power cable before servicing this equipment. Even with the power cable
disconnected, high voltage can still exist on some circuits. Discharge these voltages before
servicing. Only qualified service personnel may remove covers, replace components or make
adjustments.
DO NOT SERVICE ALONE
Do not remove covers, replace components, or make adjustments unless another person, who
can administer first aid, is present.
DO NOT EXCEED INPUT RATINGS
Do not exceed the rated input voltage or frequency. Additional hazards may be introduced
because of component failure or improper operation.
DO NOT MODIFY INSTRUMENT OR SUBSTITUTE PARTS
Do not modify this instrument or substitute parts. Additional hazards may be introduced
because of component failure or improper operation.
MOVING THE POWER SOURCE
When moving the power source, observe the following:
1. Remove all AC power to unit.
2. Use two people to prevent injury.
SURFACE STABILITY

user repair. Equipment repaired beyond the effective date of warranty or when abnormal usage
has occurred will be charged at applicable rates. CALIFORNIA INSTRUMENTS will submit an
estimate for such charges before commencing repair, if so requested.
PROCEDURE FOR SERVICE
If a fault develops, notify CALIFORNIA INSTRUMENTS or its local representative, giving full
details of the difficulty, including the model number and serial number. On receipt of this
information, service information or a Return Material Authorization (RMA) number will be given.
Add RMA number to shipping label. Pack instrument carefully to prevent transportation
damage, affix label to shipping container, and ship freight prepaid to the factory. CALIFORNIA
INSTRUMENTS shall not be responsible for repair of damage due to improper handling or
packing. Instruments returned without RMA No. or freight collect will be refused. Instruments
repaired under Warranty will be returned by prepaid surface freight. Instruments repaired

1. Introduction
This instruction manual contains information on the installation, operation, calibration and
maintenance of the P Series power sources with programmable controller.
1.1 General Description
The 801P/1001P/1251P AC source is a high efficiency, light weight 800VA, 1000VA or
1250VA programmable AC power source. The output has two voltage ranges of 0-135V or 0-
270V with a frequency range of 16 Hz to 500 Hz. The maximum output current is 9.2 amps at
135 volts range and 4.6 amps at 270 volts range for the 1250VA model. The maximum output
current is 7.4 amps at 135 volts and 3.7 amps at 270 volts range for the 1000VA model. The
maximum output current is 6.0 amps at 135 volts and 3.0 amps at 270 volts range for the
800VA model.
The universal nominal input can be from 100 volts to 240 volts at 50 Hz or 60 Hz line frequency.
Simple front panel controls enable the voltage and frequency to be changed. An optional
RS232C serial interface is available for applications that require remote control and
measurements.
