The transistor is normally off when AC is healthy. See fig. 5. Inhibit The inhibit high pin should be pulled below 0.4 V to switch V1 & V Aux (V2) off. Open circuit or 2-8 V maximum to switch the output on. See fig. 6. Current Share Connecting pin 9 (-01 models) of like voltage units (3 maximum) will force the current to share between the outputs. Units share current within 10% of each other at full load. See fig. 7. I2C The I2C compatible interface can be added to the CMH250 and is used for monitoring the unit output voltage, current, internal temperature and other data points. Adjustment of the output voltage and current limit set point and identification of the unit model number and serial number are also possible. Contact sales for details.

Temperature should be monitored using K type thermocouples placed on the hottest part of the component (out of direct air flow). See below for component locations. Temperature Measurements (At Ambient 50 °C) Component Max Temperature °C PFC1 Coil 120 ° C T1 Coil 120 ° C C5 105 ° C C3 105 ° C Service Life The estimated service life of the CMH250 Series is determined by the cooling arrangements and load conditions experienced in the end application. Due to the uncertain nature of the end application this estimated service life is based on the actual measured temperature of a key capacitors with in the product when installed by the end application. The worst case of the two figures should be taken as the indicative service life in 24/7 operation.
