Camping & Caravan If you require an Inverter for your camper or caravan recreational use you should be aware of the following. Microwave ovens If your microwave is labelled as 600W, this relates to cooking power. The actual power required from the batteries is approximately twice as much, i.e. (1200W). You also need to consider that the actual cooking time will depends on the peak voltage of that your Inverter can supply. Safety Latronics Inverters do not have any connection between AC and DC. The 240v AC is NOT connected to any DC component in the inverter. Hence we can claim isolation between DC input and AC output of 3500V via our toroidal transformer. Most other manufacturers feed the 240V AC output back onto a circuit board and the AC-DC isolation is achieved by a couple of resistors or other low voltage electronic components. Options A number of options are available for vehicular applications, including; Mounting Brackets, Vibration proofing (ruggedisation), Conformal Coating and other Customer specific modifications. Some vehicles have the battery positive connected to the chassis (earth). Latronics Inverters can be used in such vehicles due to their inherent (3,500 Volt) DC to AC isolation. Can I fit an inverter with a RCD to a vehicle? Latronics® inverters can be fitted with an earth leakage device or RCD, however in order for these devices to operate the earth and neutral must be bonded at the input of the RCD. In domestic wiring this scenario does not present any problems due to the large earth plane that can be created. However, in vehicles the inverter case which is connected to earth, would need to be connected with the vehicle chassis to provide an earth plane. This connection results in earth, neutral and battery negative being bonded together, which results in the loss of the isolation between AC and DC. Note: When using an RCD an earth plane must be created for a fault path back to earth in order for the device to trip. |
