Soft Start Power Inverters 24 v /12 v DC to 230 volt AC
600 W / 300 W Maximum Continuous Output Power
These devices are designed to produce mains power (230 V, AC) from a low voltage DC power source, i.e. a 24 v or 12 V battery.
They are supplied with 60 cm battery leads for temporary connection using crocodile clips. (The 300 W also has a cigar lighter adaptor for in-car use.)
The Inverters will provide up to 600 W /300 W continuous Power and up to 1000 W /600 W surge Power via a British Standard Socket BS1363.
The AC output is in the form of a 3-level modified sine wave with THD ≈ 25%.
Output regulation is achieved by using pulse width modulation (PWM), maintaining the output power to be equivalent to that of 230 V rms sine wave, within ± 5%.
The Output Frequency is maintained at 50 Hz ± 0.4% by an internal stable R-C oscillator.
Soft start circuitry is included to enable the device to cope with switch on current surges, for example with inductive or capacitive loads.
These inverters also incorporates micro-controller protection against: input over-voltage/ under- voltage, output overload/short circuit.
They are cooled by a micro–controlled cooling fan which operates progressively as the power increases.
The controller will automatically shut down the inverter at 65 °C and only re-start it again when the temperature has fallen to below 50°C.
An audible alarm sounds to indicate overload, over-temperature or low input voltage.
The input is reverse polarity protected by a 35 A fuse in the DC positive input.
The blade type fuse holder is available externally at the rear of the instrument for the 300 W type, and internally for the 600 W version.
This Inverters are Class I devices, housed in a metal case with an external protective Earth terminal.
They are internally bonded for safety, DC Negative to Case to AC Earth Socket.
We recommend that they be used with an external earth connection.
For additional protection against cable faults or moisture ingress, they should be used with a Type “A” portable residual current circuit breaker (commonly known as an RCCB or RCD).
These devices are ideal to power a caravan or small house low energy lighting system, or low current appliances such as a TV, Radio or Laptop Computer.
IMPORTANT SAFETY NOTE FOR SOLAR COLLECT INVERTERS
THESE INVERTERS ARE DESIGNED FOR INDEPENDENT USE ONLY. THEY SHOULD NOT NORMALLY BE CONNECTED TO DOMESTIC HOUSEHOLD WIRING, WHETHER OR NOT THE BUILDING IS GRID CONNECTED AT THE TIME.
FOR SUCH PURPOSES A GRID–TIE INVERTER IS USUALLY EMPLOYED.
SHOULD THE INVERTER BE USED AS PART OF A PERMANENT INSTALLATION, SUCH AS A STANDBY SUPPLY POWERED BY A SEPARATELY CHARGED BATTERY, THEN THE OUTPUT MUST BE PRESENTED ON AN INDEPENDENT SOCKET.
A FREE LEAD WITH A PLUG MUST BE CONNECTED TO THE CIRCUIT OR EQUIPMENT TO BE POWERED.
THE CHANGE OVER FROM THE MAINS OR GENERATOR TO THE INVERTER MUST BE ACCOMPLISHED BY SWAPPING THE PLUG OVER FROM THE MAINS TO INVERTER MANUALLY.
IF POWERED FROM A VEHICLE BATTERY, THEY CAN BE USED WITH NEGATIVELY EARTHED VEHICLES / SYSTEMS ONLY.
