IMS150/300/600/1000/1500/2500 (12/24V) Modified Sine Wave Inverter User Manual IMPORTANT NOTICE: This product is not intended to be use by children or persons in poor health without supervision. Please read this manual thoroughly before use. CAUTION: Each model is design to work up to its maximum rated power load. Please check carefully to ensure applications used are within the rated power range.
INTRODUTION: Thank you for choosing this Modified Sine Wave Inverter. This inverter is capable of converting DC power input to AC power output that has similar output signal wave as normal domestic mains. Unlike pure sine wave inverters, modified sine wave inverter is not recommended for powering voltage sensitive or inductive equipment.
FRONT PANEL: - ON/OFF SWITCH – rocker switch to switch unit on and off - POWER INDICATOR – solid green LED indicates unit has been switched on - FAULT INDICATOR – solid on or flashing red LED indicates fault has occurred, refer to fault code for interpretation - USB POWER SOCKET – 5V 1.
Mounting – The unit should be mounted horizontally, we do not recommend mounting the unit vertically. Connection: - Please ensure the ON/OFF switch on the inverter is in the OFF position and the voltage of power source matches the required inverter input voltage, if the power source is from a DC power supply please ensure it is switched off also - Connect the invert to battery / DC power source. Using provided black cable; connect the black negative terminal to the negative output of the power source.
For running the inverter on a DC power supply, it is important the check the current from power source is sufficient to run the inverter at full load. The required current to allow the inverter to operate at full load can be estimated from the continuous output power of the inverter and input power voltage.
24V OUTPUT – SERIES CONNECTION (voltage increase current remain) 24V OUTPUT – SERIES/PARALLEL CONNECTION (both voltage and current increase) SAFETY INSTRUCTION: Please note the following instructions should be carefully followed as any incorrect installation or misuse of the inverter may cause harm to user and damage apparatus.
when in use, please discontinue use immediately and contact technician or retailer - This inverter is design to be maintenance free, but requires occasional attention as dust may build up after period of time. To clean dust off, please switch off power from inverter and unplug AC plug. Carefully clean unit with a dry cloth.
TROUBLESHOOTING REFERENCE SYMPTOM ON/OFF switch is switched on, LED does not light, buzzer is off, no AC output. POSSIBLE CAUSE There is no DC power from the input terminals Polarity of the DC input has been reverse connected Buzzer sounded once only when switch on, power LED on, no AC output. Buzzer sounds 2 times and red light flashes 2 times every 8 seconds Buzzer sounds 3 times and red light flashes 3 times every 8 seconds 1. Loose AC output connections. 2. Short circuit on AC output load.
INTERFERENCE: It is not suggested to use modified sine wave inverter to power acoustic equipment. As the modified sine wave power signal will induce distortion signal to the sound signal within equipment if circuitry is not well isolated. This will cause a continuous “hum” or “buzz” background noise. Also inverter may cause interference to TV signals. The interference can be minimising by adding an inline aerial filter between the TV and TV antenna.
