Model PWS1000 Power Supply Installation & Operation Manual
INTRODUCTION All new Current Mode switching design offers increased power and reliability in a compact package. Extra input and output filtering reduce EMI to extremely low levels. Reliability features include an input fuse, thermal shutdown, current limiting and output short circuit shutdown with automatic recovery. The output voltage is easily adjusted 0.5 volts above or below the standard output voltage. The model PWS1000 Power Supply supplies either 12, 24 or 48 VDC from a 110 or 220 VAC power source.
IMPORTANT SAFETY INSTRUCTIONS 1) SAVE THESE INSTRUCTIONS — This manual contains important safety and operating instructions for power supply. 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.
INSTALLATION MOUNTING Mount the unit in a DRY location. Allow at least 4 inches of clearance around the heat sink fins for adequate cooling. POWER CONNECTION The unit is supplied with a 5 foot power cable. This should normally be adequate to connect to a source of power. If you must extend the power cable be sure to use a 3 conductor grounded type extension cable. For hard wiring to a source of power, cut off the plug, and strip the wires as necessary.
LOAD SHARE OPTION The units may be configured for load sharing if they are equiped with the optional output isolation diodes. To confirm that your unit has these diodes, use an ohmmeter to measure the resistance OUTPUT 1 OUTPUT 2 OUTPUT 1 OUTPUT 2 between the two positive output terminals. If the diodes are present the terminals will measure as not connected. If the diodes are NOT present, the terminals will measure as a short circuit.
TROUBLE SHOOTING This unit provides LED indicators and a buzzer to help diagnose any problems. The unit should sound the buzzer to alert you prior to shutting itself down. You should immediately check the indicators to determine the cause of the shutdown.
Dry Contact Relay To use your dry contact output fail relay you must connect a 9-pin D connector to the unit. You must use pins one and six as is indicated on page 7 in the remote connector diagram. The relay is factory preset to fail in the closed position when the low output LED and buzzer come on. If you wish to have the relay fail in the open position when the low output LED and buzzer come on, you must take the cover off the unit and move the jumper to the other position on J22.
REMOTE CONNECTOR This connector is located on the side of the unit.
