  • Page 2 TABLE OF CONTENTS Features and Specifications Controls and Panel Layout Precautions Operation Downloaded from Elcodis.com electronic components distributor...
  • Page 3 FEATURES / SPECIFICATIONS Input Voltage: 100~127VAC Maximum Output Voltage 145VAC (assumes 110VAC input) Maximum Output Current Voltage Meter Analog 0~150 Volt Current Meter Analog 0~10 Amp Overload Protection Included 8A fuse. May be replaced with lower value fuse to provide lower maximum current output.
  • Page 4 CONTROLS AND PANEL LAYOUT Line Fuse This fuse interrupts the power prior to the isolation transformer and should only be replaced with the same type of AGC, 10A fast blow type. Power-On Switch with Built-In Pilot Lamp Placed in the up position, the unit will be powered on and the indicator light will be illuminated. Variable Voltage Control This rotary control adjusts the output voltage from zero (counterclockwise) to full voltage (clockwise).
  • Page 5 PRECAUTIONS SAFETY AC power supplies are sources of high voltage. Improper or careless use could result in fatal electrical shock. Observe common sense safety precautions when using this and other electronic devices. INPUT POWER These instruments are intended for use with 120V, 60Hz line voltage. Do not operate with 50Hz line voltages, or 220~240VAC volt power systems.
  • Page 6 OPERATION PROCEEDURE Ensure that the Isolated Variable Power Supply is connected to the proper 120VAC, 60Hz power source. The wall outlet MUST be a three-wire grounded type, with a good earth ground. Turn off the AC power supply and set the OUTPUT VOLTAGE control to the minimum position (fully counterclockwise).
