  • Page 4: Introduction

    1． INTRODUCTION Your new SAMLEX VR-Series power inverter is one in a series of the most advanced DC to AC inverters available today. With proper care and appropriate usage, it will give you years of dependable service in your car, truck, RV or boat.

  • Page 5: Controls, Indicators And Connectors

    2． CONTROLS, INDICATORS AND CONNECTORS Figure 1 & 2 detail the front & back panel of the inverter. The front panel provides two LED indicators. A green LED shows proper operation when lit. The red LED shows inverter shutdown from overload, over voltage or over temperature.

  • Page 6: How Your Inverter Works

    (See Figure 4). The modified sine wave produced by the VR175/VR250/VR400 inverter has an RMS (root mean square) voltage of 230 volts, which is the same as standard household power.

  • Page 7: Installation/Environments

    Example: lf a load is rated at 100 watts AC, the power source must be able to deliver: 100 divided by 10=10 amperes CAUTION: The SI-A2-VR175/VR250/VR400 must be connected only to batteries with a nominal output voltage of 12 volts. The unit will not operate from a 6 volt battery, and will sustain permanent damage if connected to a 24 volt battery.
  • Page 8 If the inverter is to be used for extended periods at power levels above 175 watts, direct connection to the power source is required. Use the provided cables to connect the VR250/VR400 directly to the 12 volt power source using the following guidelines: 1.

  • Page 9: Connection To Load

    CONNECTION TO LOAD The inverter is equipped with a universal AC power receptacle. Plug the cord from the equipment you wish to operate into the AC receptacle. The green LED indicator lights to indicate that the inverter is functioning. Make sure the combined load requirement of your equipment does not exceed inverter’s output rating.

    5． OPERATING TIPS RATED VERSUS ACTUAL CURRENT DRAW OF EQUIPMENT Most electrical tools, appliances and audio/video equipment have labels that indicate the power consumption in amps or watts. Be sure that the power consumption of the item you wish to operate is rated at 175/250/400 watts or less.

  • Page 11: Protective Features Of The Inverter

    6. PROTECTIVE FEATURES OF THE INVERTER Your inverter monitors the following potentially hazardous conditions: OVER TEMPERATURE PROTECTION – If the temperature inside the inverter is too high, the unit will automatically shut down. Allow the unit to cool for at least 15 minutes before restarting after a heat-related shutdown.

  • Page 12: Common Problems

    7. COMMON PROBLEMS “BUZZING” SOUND IN AUDIO SYSTEMS: Some inexpensive stereo systems and “boom boxes” emit a buzzing sound from their speakers when operated from the power inverter. This occurs because the power supply in the electronic device does not adequately filter the modified sine wave produced by the inverter.

    8. TROUBLESHOOTING GUIDE TABLE 1 – INVERTER POWER SWITCH TURNED ON TROUBLE/ INDICATION POSSIBLE CAUSE SUGGESTED REMEDY No AC output; DC input below 10 volts Recharge or replace battery Red LED lit Green LED not lit Inverter Remove or reduce load, overheat thermal wait for inverter to cool.

  • Page 14: Fuse Replacement

    9． FUSE REPLACEMENT This inverter is protected by our integral electronic circuit and will automatically reset. More than that, this inverter is equipped with a fuse that is located inside the inverter. Normally, this fuse will not blow unless there is a serious problem occurs.
