  • The unit includes an RS232 communication option called UPSCOM which can monitor the output parameters and any abnormal conditions that have occurred in real time.


  • This will report all parameters including input and output voltages, currents, frequency, battery voltage, battery current, and many other functions.


  • Real time status, data, and historical events are displayed via the LCD display. The FC parameters, real-time clock, inverter, and buzzer can also be set through this LCD, which is backlit by LEDs for visual clarity.


LEDs representing all important operational information provide feedback to the user. LED descriptions are as follows:

  • INVERTER ON – FC is running normally.
  • SHORT CIRCUIT – output is in short circuit state.
  • FUSE / OVERTEMP SD – shut down due to either fuse open or over temperature.
  • INVERTER FAIL SHUTDOWN – shut down due to low inverter AC output voltage.
  • HIGH DC SHUTDOWN – shut down due to high DC bus.
  • OVERLOAD SHUTDOWN – shut down due to overload of the inverter for a period greater than the inverter can accept. The UPS will start after 7 seconds.
    70% LOAD – load connected to the output is over 70% of the Inverter rating.
    110% LOAD – load connected to the output is over 110% oh the Inverter rating.
    125% LOAD – load connected to the output is over 125% of the Inverter rating.
    150% LOAD – load connected to the output is over 150% of the Inverter rating.
  • RESERVE AC FAIL – reserve AC magnitude is out of range.
  • RESERVE FREQ FAIL – reserve frequency is out of range.
  • BATTERY LOW – DC bus (or battery) is lower than specified range, low battery shutdown will occur soon.
  • BATTERY LOW SHUTDOWN – inverter shutdown due to DC bus (or battery) lower than the acceptable DC voltage of the inverter.
  • HIGH DC – DC voltage over the acceptable DC voltage of the inverter.
  • EMERGENCY STOP – Inverter shut down activated by emergency stop switch.
  • DATA LINE – Blink when data is transmitted to or received from the communication port


When abnormal condition occurs, these LEDs will light to warn the user of the cause of the fault condition. These LEDs are:

  • RESERVE FAIL – Reserve AC input is abnormal either due to AC magnitude out of range or frequency out of range.
  • FUSE/TEMP – Either inverter fuse is open or over temperature has occurred.
  • OVERLOAD – Output is overloaded by over 110%, 125% or 150%
  • HIGH DC – This LED will light when DC input approaches high-line limit.
  • BAT LOW – This LED will light when the DC voltage is low.
  • BAT LOW STOP – This LED will light when the DC voltage is lower than specified range.
  • FAULT – The inverter is off due to abnormal conditions such as overload, short circuit, high DC, fuse over temperature, bypass breaker on emergency stop.


The audible alarm will beep under either one of the following conditions:

    > 110% beep once every 3 seconds
    > 125% beep once every second
    > 150% beep twice every second
  • INVERTER IS SHORT CIRCUITED – Beeps continuously
  • FUSE OPEN– Beeps continuously
  • HEAT SINK OVER TEMPERATURE – Beeps continuously
  • HIGH DC SHUTDOWN – Beeps continuously
  • BYPASS ON STOP – Beeps continuously
  • EMERGENCY ON STOP – Beeps continuously
    The buzzer will also beep once every time the inverter is switched on or off to acknowledge to the user that his key entry is valid and accepted.temperature, bypass breaker on emergency stop.


    • UPScan Remote Monitor Panel: This is a hand held remote display and control module with LCD and LED display that can monitor up to 99 FCs at a remote distance of up to 3,000 feet via RS-485.
    • RuggedizationRuggedization is highly recommended for harsh environment applications, and includes conformal coating of the FC’s PCBs to protect against humidity, condensation, and fungus growth. For military applications, we offer more structural ruggedization, as well as shock mounts, to comply with such standards as MIL-S-901, MIL-STD-810, and other demanding MIL-Specs. This option does not affect size or weight.
    • NETAGENT:  This provides capability to monitor the FC over the internet.  It includes the appropriate additional SNMP card and microprocessor.  The software required is provided by Megatec at additional cost.  When equipped with this option, the user can connect a CAT-5 cable for interface to the external LAN.
    • Complete Spare Parts Package: We offer a comprehensive spare parts package that includes one of each board, spare fuses, spare semiconductors, and spare fans.  These spare parts kits are priced lower when ordered with the initial order then if they are ordered later on.
    • Factory Turn-On Service: We offer a turn on service for a fee that will ensure the unit has been properly installed and the full warranty is in effect.  (Failures caused by incorrect installation are not covered by the warranty.)  If this option is selected, the customer will also automatically receive an additional 3 months added to the warranty at no additional charge.  This service is provided by factory engineers, not third party engineers. Pricing is dependent upon location, number of units, airfare rates, etc. Please contact us for more details if interested.
    • Customized EPO: This Emergency Power Off (EPO) Feature can be tailored to trip off current breakers or perform other inhibits per specific customer applications.
    • Shock and Vibration Mounts: A wide selection of mounts are available for compliance to MIL-S-901, MIL-STD-167, and other related standards.
