![]() Today’s RV’s come with a 12-Volt charger built in the power center but more often a stand-alone charger mounted behind the power center. In the mid 90’s manufacturers changed to a 12-Volt charger and eliminated the power converter as it was redundant (this also eliminated the pesky relay). That battery was charged by a separate 12-Volt charger often build into the power center. When you unplugged from 120-Volt a relay would switch the system to the 12-Volt battery. Power converter is a transformer that converts 120-volt to 12-volt. In the 70’s up until the mid 1990’s the low voltage system used a power converter that powered the low voltage system when an RV was plugged into shore power (120-volt). High voltage 120-volt system powers the 120-volt plugs, microwave, air conditioner and entertainment center. The low voltage 12-volt powers lights, water pump, stereo, furnace fan, and fridge controls. Motorized products are a separate discussion.Ī towable RV has a low voltage system and a high voltage system. ![]() Motorized RV’s have some similarities but typically are more complicated having a chassis and coach systems. In this post I will cover the power system of a towable RV’s. Over the years I have seen many changes in the RV power system. Today we are referred to as RV Technician. I was the 35th to be certified in Alberta as a RV Mechanic. In Alberta in 1985 “Recreational Vehicle Mechanic” became a compulsory certification trade. IOTA’s Dual State Charging, tight Line/Load Control and Switch-Mode design make the DLS-55 Converter/Charger a powerful, efficient, and compact battery charging and power conversion solution for almost any application.I started as a technician in the RV Industry. The IOTA DLS-55 is also an ideal component for photo-voltaic systems, taking AC input from the system's inverter or line power from grid-tie systems and converting it to DC voltage for maintaining auxiliary battery banks. Over time, as the battery nears its full capacity, the DLS-55 will automatically drop the current, providing a float-charge to the battery to prevent self-discharge of the cells. This helps to ensure the longest possible life of the battery. The voltage is set to deliver its maximum current for the necessary period of time to minimize undue stress to the battery caused by heating of its cells. As a power supply, the unit's tightly controlled regulation allows the user to operate a nominal 12VDC load up to 55 amps.Īs a battery charger, the DLS-55 will maintain the battery, delivering its full-rated current when the battery capacity falls sufficiently low. The DLS-55 Converter/Charger converts nominal 108-132 AC voltage to 13.4 DC voltage for both DC load operation and 12V battery charging. Additionally, features such as the IQ Smart Charge Controller option allows the DLS-55 to maintain batteries while the RV is not in use. In most cases we can! Call us at 1-80 or e-mail us at IOTA DLS-55 Converter/Charger was designed with the RV user in mind.providing clean output for the operation of DC equipment, virtually silent fan operation, and the built-in protection features that guard the unit against low transient AC voltage from pedestal supplies. If you find a lower advertised price on any IOTA Engineering product, give us a chance to match or beat it.
