700W 230V/115V Mains Backup Systems

With High Surge Capability

Temporary Picture

 

GENERAL DESCRIPTION:  These static inverters convert battery power into 230V AC RMS 50 Hz  or 115V AC RMS 50/60 Hz (depending on model).  The supply is suitable for operating domestic appliances, small power tools, etc.  They are particularly suitable for small refrigerators and microwave ovens because of their high surge capability.  They can be permanently connected to 230V AC (115V AC) mains and will automatically change over to battery operation when the mains fails.  The normal continuous power rating into a resistive load is 700 watts, with intermittent operation at 800 watts.

When the mains input socket is connected to functioning mains, it supplies the connected appliance.  The battery function may be switched off by the switch on the front face, disabling automatic change-over.

Dual outlet sockets are fitted to the unit in a variety of configurations. The input is isolated from chassis (floating). The output is isolated via a safety barrier from the input.

The output is a stepped odd function wave AC output of nominally 230V/115V RMS, with a peak voltage appropriate to UK (US) mains, corresponding to a quasi sine wave. This output, suitable for switched mode supplies, is required for machines employing a mains transformer, making it suitable for almost all equipment.

The battery input is via internal 5mm stud terminals. The unit may be turned off and on remotely, by a low current control input to a 6.35mm spade terminal. An earth stud is fitted on the outside of the box for chassis connection.

BATTERY SELECTION:  Only heavy duty (high discharge rate) batteries are suitable as a power source. Fully sealed types should be used in enclosed spaces (especially inside the home). Ordinary car batteries are only suitable in well ventilated areas.  Batteries are not supplied with the unit, the customer must use their battery / battery banks.

Careful selection of the customers battery bank size will determine the hold time of the load in the event of mains failure.  For example let us take a 90 watt fridge.  Using a 12V battery system the current taken from the battery will be 1A for every 10W of load (see table below), therefore 9A, 90/10=9.  If a 55Ah battery is used it will provide 6 hours of hold up time, 9X6=54.  Remember to bear in mind it is not a good idea to heavily discharge a battery as it will shorten it's life span, a 50% discharge level is generally recommended in order to maximise battery life time.  The customer can select further hold up time by selecting a larger battery or by placing several in parallel.

CAUTION:  This adapter is supplied on the basis of the user determining the suitability for the purpose for which it is to be used. Not for life dependent use. Total Live to Neutral load capacitance must not exceed 2.0uF.
