IMPORTANT & SAFETY INSTRUCTIONS

SAVE THESE INSTRUCTIONS — This manual contains important safety and operating instructions for the converter.

ALL POWER SUPPLIES

1. WARNING – Unless the label specifically states that the power supply may be used for battery charging, it must NOT be used for that purpose.

2. Do not expose power supply to rain or snow.

3. Use of an attachment not recommended or sold by the power supply manufacturer may result in a risk of fire, electric shock, or injury to persons.

4. Do not disassemble power supply; take it to a qualified serviceman when service or repair is required. Incorrect reassembly may result in a risk of electric shock or fire.

5. To reduce risk of electric shock, disconnect power supply from AC supply before attempting any maintenance or cleaning. Turning off controls will not reduce this risk.

6. DC CONNECTION PRECAUTIONS i. Connect and disconnect DC output connections only after setting power supply switch to off position.

DANGER — Never alter the AC cord or plug provided. If it will not fit the outlet, have the proper cord installed by a qualified electrician. Improper connection can result in a risk of an electric shock. Your power supply should be grounded to reduce the risk of electric shock. The power supply is equipped with a grounding conductor and a grounding plug.

Analytic Systems does not recommend the use of the PWS120 Series Power Supplies in life support applications where failure or malfunction of this product can be reasonably expected to cause failure of the life support device or to significantly affect its safety or effectiveness.

Analytic Systems does not recommend the use of any of its products in direct patient care.

Examples of devices considered to be life support devices are neonatal oxygen analyzers, nerve stimulators (whether used for anesthesia, pain relief, or other purposes), autotransfusion devices, blood pumps, defibrillators, arrhythmia detectors and alarms, pacemakers, hemodialysis systems, peritoneal dialysis systems, neonatal ventilator incubators, ventilators for both adults and infants, anesthesia ventilators, and infusion pumps as well as any other devices designated as “critical” by the U.S. FDA.

Introduction

The PWS120 & PWS240 Power Supplies are MosFet based switchmode power supplies designed for high reliability, high efficiency and minimum size. Circuit innovations reduce output ripple to levels previously available only from bulky, inefficient linear power supplies.

Current limiting and safe operating area circuitry protect the transistors. A crowbar circuit protects any devices powered by the unit from excessive voltage in the unlikely event of a failure.

Applications include running 12Vdc equipment from 120Vac power including VHF radios, CB radios, sound equipment, GPS receivers, plotters, 12 Volt lighting systems and automotive & marine electronics displays.

Installation

MOUNTING

Mount the unit in a DRY location. Allow at least 1 inch of clearance around the unit for adequate cooling. Do not block the ventilation slots on the sides of the unit.

POWER CONNECTION

Ensure the switch is in the OFF position. Connect the power cord to the power supply then connect the power cord to the AC source. Connect the output of the power supply to the DC load. The RED terminal is the positive output and the BLACK or WHITE terminal is the negative output.

Operation

Turn the switch to the ON position. The neon indicator in the switch should illuminate. If the indicator fails to illuminate, recheck the connection, AC outlet and the fuse inside the power supply.

This unit may be converted from 110Vac input operation to 220Vac input operation.

For instructions on this conversion please call Analytic Systems at 800-668-3884.

The PWS120 is cooled by convection and has no over temperature shutdown. Ensure adequate ventilation for cooling.

The PWS240 is cooled by convection and forced air (via a fan). The fan operates when the transformer temperature exceeds 70 degrees Celsius. If for some reason the temperature should exceed 100 degrees Celsius the unit will shut down. After the unit has cooled down it will resume normal operation.

NOTE:

Place the unit in a well ventilated, open and cool area. Do not block the openings of the fan intake at the bottom of the unit or the exhaust openings at the side of the unit!

Troubleshooting

(General)

PROBLEM: ON/OFF switch does not illuminate when turned on.

Probable Cause Suggested Remedy

No AC power available.

AC input fuse is blown.

Check AC outlet for power.

Replace the fuse with a fuse of the correct rating.

PROBLEM: AC input fuse blows as soon as power is turned on

Probable Cause Suggested Remedy

Input voltage is low

The unit is in current limit due to a large reactive load or the output terminals are shorted together

Check input voltage

Check that the output terminals are not shorted together.

Remove the load and check the output voltage. If it is normal, then the load is too much for the power supply.

PROBLEM: The output voltage drops as soon as the load is applied.

Probable Cause Suggested Remedy

The unit is going into current limit.

Reduce the load current to less than the rated current limit.

Devices such as motors, compressors, relays and lamps can have high inrush or starting currents. Please ensure these currents do not exceed the current limit rating of the power supply.

The unit (PWS240) is shut down due to over temp Check that the fan has not failed or the vent openings are not blocked.

DEFECTS OR DAMAGE

If after checking all of the above and the problem persists, you may assume the unit is defective or damaged and it must be returned for repair.

WHEN USING THE POWER SUPPLY WITH RADIO TRANSCEIVERS

• This power supply generates, uses and can radiate RF energy as per limits laid down under class “B”, Part 15 of FCC rules. Position the radio, antenna and power supply to minimize any received spurious noise from the power supply and excess RF energy from the transmitter. Ideally, for a 100 watt HF installation, the antenna should be at least 40 to 50 feet from the power supply to eliminate the effects of transmitter energy on the power supply and induced noise from the power supply to the receiver.

• If the supply fails to turn on, check that the transceiver is off. The supply may turn on with a lower load (transceiver in the receive mode) but may not turn on if the

6

transceiver is in the transmit mode (high current consumption).

• The antenna being too close to the equipment may cause a slowly oscillating buzzing carrier heard in the receiver. A loose coaxial connector or a broken or missing ground may aggravate this problem. Normally, these noises will be below the background or

“band” noise. RF feedback from the transmitter may create instability in the power supply causing a poor sounding, raspy or unstable transmitted signal. A distance of 40 to 50 feet between the antenna and equipment is generally recommended for any 100 watt HF installation. Position the antenna as far and as high from the equipment as possible.

• The power supply may turn off due to excessive transmitter energy being coupled into the AC and the DC lines. Either your antenna is too close (less than 10 feet) or the antenna system is not radiating properly. First check the antenna system SWR. Then, if necessary, relocate either the antenna or the equipment further apart.
