    Victron Energy Autotransformer 1. Safety • These instructions are for use by qualified personnel only. Do not perform any servicing or installation other than that specified in the operating instructions unless you are qualified to do so. Incorrect installation or servicing may result in a risk of electric shock, fire, or other safety hazards.

  • Page 4: Introduction

    The Victron Energy Autotransformer has the ability to use a ground/earth relay to create a Neutral to Ground bond in the AT itself, if coupled with a Victron Energy MultiPlus or Quattro and the relay terminals are interconnected.

  • Page 6: Stepping Up Voltage

    Victron Energy Autotransformer 2.3.2. Stepping Up Voltage Alternative to Stacked Inverters. Loads such as deep well water pumps and air conditioning units sometimes require Split-Phase 120/240Vac power. When the available AC power source is not what is needed in the installation, the autotransformer can create the needed voltage by doubling the incoming voltage.

  • Page 7: Stepping Down Voltage

    Victron Energy Autotransformer 2.3.3. Stepping Down Voltage Flexibility in Using Split-Phase for Single-Phase Inverters One case for using the autotransformer to step down voltage could be in installations that use a Split-Phase generator and a Single-Phase inverter, the autotransformer makes it possible to use all available power from both legs of the generator to power loads and to charge batteries.

  • Page 9: Ground Relay

    Victron Energy Autotransformer 2.4. Ground Relay In most energy systems for residential or mobile use a TT configuration is used, which means the Neutral of the AC system is grounded. This is to ensure the GFCI breaker will trip in case there is an earth failure (The connection N/PE will ensure a current will flow in the secondary circuitry which is detected by the GFCI).

  • Page 10: Over Current Protection

    Victron Energy Autotransformer 2.6. Over Current Protection In case of over current the MCB will switch off. Disconnect some of the load. The MCB is for Over Current and Temperature Protection and switching the unit ON/OFF. 2.7. Sizing Limitations The Autotransformer comes in two models, a 32A model and a 100A model. This value is defined in the amount of current there can be in pass through, so in other words the current which is forwarded without being converted.

    Victron Energy Autotransformer 3. Installation 3.1. Installation Considerations Ensure that the Autotransformer is used under the correct operating conditions. Never operate it in a wet or dusty environment. The AT is rated to IP21. Ensure that there is always sufficient free space around the product for ventilation (10cm or 4 inches), and that ventilation openings are not blocked.
