SAFETY SUMMARY
This power source contains high voltage and current circuits which are potentially lethal.
Because of its size and weight, electrical and 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 801RP/1251RP unit uses a North American ferrule type fuse rated at 15A 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. This product is
designed to operate in a controlled environment. Do no expose to rain or snow.
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
1. Operate the power source only on a level surface.

1. Introduction
This instruction manual contains information on the installation, operation, calibration and
maintenance of the RP Series AC power source.
1.1. General Description
The 801RP/1251RP AC source is a high efficiency, light weight 800VA 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 for the 1251RP is
9.2 amps on 135 volts range and 4.6 amps on 270 volts range.
The maximum output current for the 801RP is 6 amps on 135 volt range and 3 amps on 270
volts range.
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, current limit and frequency to be changed.
An optional RS232C and IEEE 488 interface is available for applications that require remote
control and measurements.
