Ozoniser module kills germs, ready for consumer apps

Murata has recently debut its ultra-compact ozoniser module, the MHM500. The company's latest offering is constructed on a low temperature co-fired ceramic (LTCC) element. Using a discharge electrode and a dielectric electrode within the LTCC board, the ozoniser creates a stable supply of ozone. The device's electrodes are also fabricated within the LTC element, providing a long life characteristic.

Comprising both the LTCC element and a power supply module, the MHM500 can be used to generate ozone in a broad range of consumer, industrial and automotive accessory applications. Bacteria can proliferate in many appliances such as refrigerators and dish washers resulting in mildew, odors and creating potential health risks. Previously, ozone-creating units have been too large and expensive to incorporate into consumer appliances, but now, the compact MHM500 module makes this possible. The ozone element measures 14.2x31.5x17 mm, and the power supply module 36x50x24mm.

The module operates from a + 12 VDC input voltage and has a low power consumption of approximately 1 W. Ozone generation performance is 2.5 mg/h maximum. A remote signal input controls the operation of the unit without the need to turn ON/OFF the input supply. The high voltage output of the power supply module incorporates an over-current and output protection circuit that can isolate the element supply in case of a fault condition.
