Quantity in Stock: 7
Full Product Description



Progressive Industries EMS-PT50C

  • 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: If the AC power is interrupted, or the EMS detects a fault condition, the built-in time delay is activated.  There is 136-second (02:16) time delay.

  • Five (5)-Mode Surge Protection:  This feature provides full surge protection L-N, L-N, L-G, L-L and N-G.  Total Joule rating is 3,580, 88,000A surge current.  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 E-1.

  • 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 E-2 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 E-7 or E-8 error code on the digital display.

  • Accidental 220V Protection: If 240 volts is detected when plugging into AC 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 E-3 for the error.  (NEVER BYPASS THE EMS WHEN THIS OCCURS.)

  • Integrated Information Panel: 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.

  • Weather Resistant: Can be exposed to elements, but may not be submerged.

  • Microprocessor Controlled: The computer is driven by a state-of-the-art microprocessor that is programmed with software to drive the entire EMS.

  • Lock Bracket: Allows the user to secure the unit to power source to prevent theft.
