WARNING !!
Complete Grounding of this unit is necessary for
the safe operation of this equipment. Disconnect
inputs before ungrounding this equipment

GENERAL SAFETY PRECAUTIONS
This equipment can produce POTENTIALLY LETHAL VOLTAGES!
Improper operation or test practices may result in injury or death to the
operator or surrounding personnel.
The operation of High Voltage test equipment should only be performed by
personnel familiar with HIGH VOLTAGE testing and safety procedures. The
operator of this equipment must be aware of all hazards associated with
High Voltage testing. The operator is responsible for himself and others in
close proximity of the testing area.
Some General Safety Practices for working with High Voltage Test
Equipment have been listed below for your reference.
•Become familiar with your instrument before performing an actual
test
•Know your work area, check that all circuits are de-energized and
locked out.
•Never work alone; always work with another qualified worker.
•Mark off entire work area with barriers and warning tape.
•Make all personnel aware of your testing activities.
•Be aware of dangerous conditions that may arise from energizing a
test specimen.
•Never modify test equipment, modifications to equipment could
introduce an unknown hazard or hinder a designed-in safety feature.
•DO NOT operate damaged equipment. Remove power, and do not
use the equipment until safe operation can be verified by service-
trained personnel.
Phenix Technologies, Inc. assumes no liability for unsafe or improper use of test
equipment.

SECTION 1: INTRODUCTION & SPECIFICATIONS
The Phenix Technologies VMS-3 Portable Power Supply is well equipped with the various features
listed on the specifications page to allow for the easy testing of the operational voltage/current of
electro-mechanical devices. The VMS-3 allows the user to dial in an output voltage or current to
determine the operational voltage or current levels of various electro-mechanical devices. Both the
voltage and current output levels can be simultaneously read and monitored with the highly
accurate, onboard meters. The VMS-3 is ideal for running small motors, energizing power circuits,
operating circuit breakers, powering substation relays or for unregulated charging of substation
batteries. The separate output terminals for both AC and DC voltage provide convenient hookup
configurations depending on the type of component being tested.

SECTION 2: CONTROL AND METERING DESCRIPTION
(Key numbers refer to Figure 1)
1. Input Power. Plug the included power cord into the unit and a 120VAC, 10A supply.
2. Main Power Indicator Lamp. Lights when main power circuit breaker is energized and in
the ON position.
3. Main Power Circuit Breaker. Serves dual function as main switch and provides overload
protection for all circuits in test set.
4. AC Digital Voltmeter. Provides continuous display of AC output voltage in Volts.
5. AC Digital Ammeter. Provides continuous display of AC output current in Amps.
6. DC Digital Voltmeter. Provides continuous display of DC output voltage in Volts.
7. DC Digital Ammeter. Provides continuous display of DC output current in Amps.
8. AC Overload Circuit Breaker. Circuit Breaker will open once AC output exceeds 10A.
Close switch to reset breaker.
9. Main Variac Knob. Adjusts voltage and current output levels.
10. DC Overload Fuse. Fuse will blow when DC output exceeds 5A. Replace fuse via panel
fuse holder when needed.
11. AC/DC Output Selector Switch. Toggle to select either AC or DC output.
12. AC Supply Binding Posts. Connect included output leads here to apply AC voltage to a
test object.

SECTION 3: OPERATION AND CALIBRATION
OPERATION
Setup
1. Connect input power supply to on board terminal block on the rear of the panel with
115VAC or 120VAC, 10A source.
2. Ensure Main Variac knob is dialed to its zeroed out position before connecting output
terminals.
3. If either of the two Overloads is tripped, close the switch to reset the AC output breaker or
replace the DC output fuse.
4. Verify power is off and then connect the output supply via the two sets of binding posts
depending on whether AC or DC will be used and hook up the component to be tested with
the leads provided.
Operation
5. Turn on main circuit breaker switch to power on unit. Note indicator light comes on.
6. Slowly raise the output voltage by turning the Main Variac clockwise until the desired output
voltage or current is reached for the intended application or test.
7. Upon completion of testing, turn off main power by switching off the main breaker before
disconnecting the output leads from the test component.
8. WARNING: For safety reasons, dial back the Main Variac knob to its zeroed-out position
before and after each use.

OPERATION AND CALIBRATION
CALIBRATION
Your VMS-3 portable power supply itself does not require any calibration for normal operation.
The onboard digital Voltmeters and Ammeters will also hold their normally calibrated settings
during the lifetime of your VMS-3 for all normal indoor operations. In the rare case that any meter
needs calibration adjustments, the procedure for doing so should be performed by qualified
technical personnel such as the Phenix Technologies Service Department during a scheduled
service appointment.
MAINTENANCE
During the lifetime of your portable power supply, certain items will need replacement. Common
replacement parts are listed on page 7-1 under “Recommended Spare Parts.”
