MHM403 series data sheet Ionizer module 1. Key Features Generates negative 20 million Ions typ. (pcs per cc) MHM403 generates minimal ozone, less than 0.1mg per hour Compact design with three ion element wire length options Integrated high voltage power supply, perfectly matched with the ionizer 2. Description The MHM403 Series is effective for applications such as static elimination by generating a large amount of negative ions and positive ions with minimal ozone. The MHM403 features an integrated high voltage power supply with negative high voltage and positive high voltage. All these features are packaged in an elegant and compact form factor, able to fit most application environments. MHM403 does not have needle terminal. 3. Circuit & dimension 3.1 Typical Application Circuit No needle terminal. Only output wires. 3.2 Mechnical dimension - Please see Fig.1 of the structure of Ionizer module 4. Rating 4.1 Operating Temperature ( Ambient ) - High Voltage Power Supply (HVPS) : -10+50 4.2 Operating Humidity - 20%RH80%RH ( no dew deposit ) The value of the ion amount and Ozone amount will decrease at low temperature and high humidity. Therefore, the value of the current will be specified at 252 and 5010%RH. 4.3 Part number (Ordering Guide) : MHM403 series Series name Partes number Length of wire between power supply and Ion element MHM403-00 100mm MHM403 series 1.

Using MHM001 ion unit. (Note 2) Measurement conditions as per Fig.1a. Reference Section 4.4 for Pin Function. The input voltage E(100Vac) applied between red wire and black wire. Under this condition, ion amount is measured using an Ion counter : NKMH-103, Hokuto electronics. (Note 3) MHM403 series connected as per Fig.1b, with fan and Teflon tube for air sampling using an ozone dosimeter in (approx. 6.7L). The input voltage E (100Vac) will be loaded between red wire and black wire. Under this condition, ozone density will be measure by the instrument after 3min. generation.
