GENERAL SAFETY PRECAUTIONS
HIGH VOLTAGE
This equipment is capable of providing 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.

INTRODUCTION
The Phenix Technologies VMS-1 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-1
allows the user to carefully dial in an output voltage or current to determine the
operational voltage or current levels needed for the “switching state” 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 output terminals in the form of binding posts provide convenient hookup
configurations depending on the type of component being tested.

CONTROL AND METERING DESCRIPTION
(Key numbers refer to Figure 1)
1. Main Power In.
2. Main Power Circuit Breaker. Serves dual function as main switch and provides overload
protection for all circuits in test set.
3. Main Power Indicator Lamp. Lights when main power circuit breaker is energized and in
the ON position.
4. Coarse Adjust. Adjusts voltage and current output levels.
5. Fine Adjust. Adjusts voltage and current output with finer precision than coarse adjust
knob.
6. Digital Voltmeter. Provides continuous display of output voltage in Volts.
7. Digital Ammeter. Provides continuous display of output current in Amps.
8. Overload Circuit Breakers. Push button circuit breakers for each adjustment circuit.
Button will pop up when breaker is tripped, push down to reset breaker.
9. Output Binding Posts. Output connection terminals to hook up components to be tested
with the power supply.
10. Cable Storage Area. Onboard cable storage for input power cord and output clip lead
wires.

OPERATION AND CALIBRATION
OPERATION
Setup
1. Open unit and connect input power supply cord to the power inlet and a standard wall
outlet.
2. Ensure Coarse and Fine adjustment knobs are dialed to their zeroed out positions before
connecting output terminals.
3. If either of the two Overload circuit breakers are tripped, press the push button to reset the
breakers.
4. Connect the output supply via the binding posts and hook up the component to be tested
with the two leads that would “switch the state” of the component.
Operation
5. Turn on main circuit breaker switch to power on unit. Note indicator light comes on.
6. Using the component manufacturer’s current ratings as a guide, slowly dial the Coarse
adjust to within 5V of the desired level.
7. Once the output is dialed to within a ~5V margin below the desired level, slowly dial the
Fine adjust until the component activates.
8. Upon completion of testing, turn off main power by switching off the main breaker before
disconnecting the output leads from the test component.
9. Disconnect input power cord and output power cables and place back into the onboard
storage area after each use.
10. For safety reasons, dial back the Coarse and Fine adjust knobs to their zeroed out positions
before placing the unit back in storage.

CALIBRATION
Your VMS-1 portable power supply itself does not require any calibration for normal operation.
The onboard digital Voltmeter and Ammeter will also hold its normally calibrated settings during
the lifetime of your VMS-1 for all normal indoor operations. In the rare case that either 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.” With the exception
of the input and output cables, all other components that may need replacement require the
removal of the front panel from the Portable Power Supply enclosure case. This is done through
the removal of the mounting screws and washers along the perimeter of the front panel, and
pulling the panel with its attached components from the enclosure. After the needed components
are replaced, replace the front panel with the mounting screws and washers, carefully hand
tightening the screws into place. Using screwdrivers or over-tightening the screws may cause the
brass hardware to dislodge from the frame.
