Full Product Description



Progressive Industries EMS-HW50C

  • Remote Display: 14 ft cable to remote display
  • Voltage Protection: Whenever source power falls below 104 Volts, or rises above 132 volts, the EMS automatically shuts down power to the RV.  Once the AC source rises above 104-volts, or below the 132-volt level, the time delay indicator flashes for the preset time and then automatically restores power to RV.
  • Time Delay for A/C Compressor: Whenever source power is interrupted by the source or the EMS due to a fault condition, the built in time delay is activated. There are two settings on the EMS; one is 136 seconds, and the other is 15 seconds.  Consult you Air Conditioner manual to see if it has a time delay built in. If yes, use the 15-second delay.  If no, use the 136-second delay.
  • Five (5)-Mode Surge Protection:  This feature provides full surge protection:  L-N, L-N, L-G, L-G, and N-G.  Total Joule rating is 3560, response time of <1 nano second.
  • Surge Indicator: If ever a power surge damages the surge protector circuit within the EMS L-N, or L-G, the digital display error code will read E-10.  This is your indication that it needs to be replaced.
  • Reverse Polarity Protection: If source power is a reverse polarity condition, the EMS will not allow power to the RV and the error code will read E1.
  • Open Neutral Protection: If the source has an open neutral condition the display will not appear, and will not allow power to the RV.
  • Open Ground Protection: If source power has an open ground condition, the EMS will read an error code of E2 and will not allow power to the RV.
  • AC Frequency Protection: If source power frequency deviates by (+/-) 9 hertz from 60 cycles per second, the EMS will shut down source power, and indicate an E7 or E8 error code on the digital display.
  • Accidental 220V Protection: If 220 volts is detected when plugging into source power the EMS will not allow power to the RV.  If this condition occurs while power is applied to the RV, the EMS shuts off power instantly.  The display will read the voltage and the appropriate error code.
  • Remote Display: Scrolls continuously through all of the power source information:  voltage, current, frequency, error codes, and previous errors.  Each reading is displayed for 2 seconds.
  • Previous Error Code: This feature tells the user why the EMS previously interrupted power to the RV.  This is only displayed if an error actually occurs, and resets when power is disconnected to the EMS.
  • Bypass Switch: Enclosed blue jumper wire allows the user to bypass the computer circuit in the EMS in the event of computer failure, thus allowing source power into the RV.  This does not disable the surge protection portion of the EMS.
  • Modular Design: Replacement parts are designed for simple plug and play, making repairs extremely user friendly.
  • Microprocessor Controlled: The computer is driven by state of the art microprocessors that are programmed with software to drive the entire EMS.
