Emergency power source 300W with sinusoidal waveform and charging function 12V 230V Emergency power source KEMOT PROsinus-300 is an inverter with pure sinusoidal waveform and charging function is designed to supply AC voltage to consumers with a rated voltage of 230 VAC and power up to 300W: - central heating pumps - induction pumps - pumps in fireplace installations - installation automation devices using heat convectors - other devices with power supply up to 300W (500W at peak) Due to the CLEAN SINUSOIDAL waveform of the output voltage (supplying power to loads) the device ensures stable operation of loads and no effect of overheating inductive loads such as pumps or fans. Together with a 12V battery it is a complete 230 VAC guaranteed power supply unit. The unit is equipped with a battery protection system against overload, short circuit, overvoltage, too high or too low voltage and overheating. Selected parameters: - power 300W - output voltage: 230 VAC - frequency (output): 50/60Hz - output voltage shape: sinusoidal - output voltage stabilization - switching time: =85% (DC to AC) - cooperates with 12 VDC batteries - battery charging current: max. 10A - protections: against overload, short-circuit, overvoltage, too high or too low voltage and overheating - battery charge indicator - load indicator - power indicator - input voltage indicator - output voltage and frequency indicator - Permissible operating temperature: 0-40C - dimensions 145 x 180 x 240 mm - weight 4.3 kg The device can operate in three modes: 1. as an emergency power source with charging function - converts 12 VDC DC voltage supplied from an external battery to 230 VAC and recharges the external battery. 2. as a rectifier - recharges the external battery (the device must be connected to the 230 VAC mains supply). 3. as a converter - converts 12 VDC DC voltage fed from the external battery to 230 VAC alternating voltage The device is equipped with a clear and easy to read LED display with indicators of the current status The battery is not included in the set. The battery should be purchased separately selecting the capacity according to individual needs.
