Most RV's contain thousands of dollars of sensitive electrical equipment, yet we routinely put them at risk by connecting them to unknown and untested power sources. Once you're plugged in, it's too late to tell if there is bad power, the damage has most likely been done. In the first two years when we were traveling in our RV without a Progressive system, I suffered from two blown video cameras, 1 blown PC and a blown credit card terminal ($1,500 worth of damage) before I realized what the problem was. Since installing my Progressive EMS, I've been protected on countless instances. Low voltage, high frequency, reverse polarity and faulty ground. Don't gamble with your power or your life. Install a Progressive Electrical Management System today.

The EMS-HW50C unit is the portable version of the hardwired HW50C and LCHW50 units. It's features are identical apart from the fact that it is rated for outdoor use and has the display built-in to the unit. The display shows the status of the power, and any error conditions. The unit also features a lock guard - simply insert a bicycle lock through the guard and secure around the pedestal - your unit is safe and secure. We normally recommend the portable EMS units for fifth wheels, trailers and C-Class motorhomes as these can harder to install the hardwired units.

The unit also features a theft-guard - simply insert the optional Progressive Portable Lock through the guard and secure around the pedestal - your unit is safe and secure.

Can be used with your regular 50-30 adaptor, just put the adaptor on the PT50 and plug into the 30 amp outlet.

  • High/Low Voltage Protection: Whenever AC power falls below 104 volts, or rises above 132 volts, the EMS automatically shuts down power to the RV. The EMS will monitor the power and once the AC power 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 the 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 are tow settings on the EMS: one is 136 seconds (02:16), and the other is 15 seconds. Consult your air conditioner manual to see if it has a time delay built in. If so, use the 15 second delay, if not; use the 136 second delay. The factory setting is 15 seconds.
  • 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: In the event of a power surge, and the surge protector circuit is damaged within the EMS, L-N or L-G, the digital display error code will read E-10. This indicates the EMS needs to be serviced.
  • Reverse Polarity Protection: If AC 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 AC power has an open neutral condition, the display will not light, and the EMS will not allow power to the RV.
  • Open Ground Protection: If AC power has an open ground condition, the EMS will read an error code of E-2 and power will not be allowed to the RV.
  • AC Frequency Protection: If AC power frequency deviates +/- 9 hertz from 60 cycles per second, the EMS will shut down power. An error code of E-7 will be displayed when the frequency is high; and an error code will be displayed when frequency is low.
  • Accidental 240V 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.)
  • Remote Display: Continuously scrolls all of the AC power information, including voltage, current, frequency, error codes and previous errors. Each reading is displayed for two (2) seconds.
  • Previous Error Code: This feature tells the user what the previous error was and why power was interrupted to the RV. To read a previous error code, put a "P" in front of the "E" code. This is only displayed if an actual error occurs. The error is deleted when power is disconnected from the EMS.
  • Bypass: This switch is located on the remote panel, and allows the user to bypass the computer circuit in the EMS in the event of computer failure, thus allowing AC power into the RV. This does not disable the surge protection portion of the EMS; however, all other features are disabled.
  • Modular Design: Replacement parts are designed for simple plug and play, making repairs extremely user friendly.
  • Microprocessor Controlled: The computer is driven by a state-of-the-art microprocessor that is programmed with software to drive the entire EMS.
  • Weather Resistant: Can be exposed to the elements, however, may not be submerged.
  • Built-In Lock Bracket: Allows the user to secure the EMS to power source to prevent theft (7/8" diameter hole).
  • Now with LIFETIME Warranty

Sales and service April 30, 2015
Reviewer: Mark Spoeneman from Largo, FL United States  
These folks are great, I ordered several items from them at a great price.  One was back ordered but they were kind enough to let me know.  After a short delay, I got my stuff. I ordered some more things; I spoke in person this time, very friendly and he took the time to go into the warehouse to make sure he had the products in stock, which they did. Buy with confidence!
